Abstract : The aim of the current study was to investigate changes in the reproductive parameters during stress and the impact of thymoquinone during the period. The effects of stress were measured through immobilisation stress on mice. Group I was administered normal saline daily via intraperitoneal injection while Groups II and III were subjected to 2 and 6 hours of immobilisation stress respectively. Groups IV and V were subjected to stress for 2 and 6 hours respectively followed by intraperitoneal injection of 10 mg/kg thymoquinone which was continued on alternate days. The level of significance was set at p<0.05 and statistical analysis showed significant difference in testicular weight of mice in groups II and III compared to the controls but no significant difference was obtained for sperm count between all groups. Sperm motility, however, was significantly different among the groups under stress for 2 and 6 hours and that of 6 hours with the treatment of thymoquinone when compared to the controls. The histology of the testes also indicated a few alterations in comparison to the controls in the germinal epithelium and spermatogenic pattern in groups III and V.

Abstract : In order to assess soil health of Kharkhoda and Gohana blocks of Sonipat district (a part of western Yamuna canal irrigated region), important parameters namely pH, electrical conductivity (EC), texture, bulk density (BD), saturated hydraulic conductivity (HC), soil organic carbon (OC), available water retension capacity (AWRC) and non capillary pores (NCP) were measured by collecting undisturbed soil samples in nearly 66 villages. Soil physical rating index (PI) method was used to compute PI which was an indicator of soil physical health of that region. Results revealed that in Gohana and Kharkhoda blocks, nearly 90% area had pH <8.0 and EC>4 dS m-1, which indicated that soils were saline. Prediction maps of soil BD showed that 75% of the total area in 15-30 cm soil layer had BD above >1.6 mg m-3, which indicated the presence of hard pan in subsurface. HC data of subsurface layer also showed that 60% of the area had values<0.5 cm hr-1 which reconfirmed the presence of hard pan. For both surface as well as subsurface soil layers, mostly AWC was >10% which indicated adequate water retention capacity of these soils. However 85% of subsurface had poor soil aeration capacity as indicated NCP range < 10 %. Prediction map of PI for subsurface layer showed that majority of area had PI<0.4 which indicated that expected yield of the crop cannot be more than 70% of the potential yield even under normal or higher levels of fertilizer and water inputs.

Abstract : Soil is recognized as one of the most valuable natural resource whose soil pH property used to describe the degree of acidity or basicity which affect nutrient availability and ultimately plant growth. Fifty soil samples were collected and their pH was determined by using digital image processing technique. Soil colour is visual perceptual property corresponding in humans to the categories i.e red, green, blue and others. Soil colours are the parts of visual perceptual property where digital values of red, green and blue (RGB) provide a clue for spectral signature capture of different pH in soil. For the capturing images, digital camera was used. Transformation of the multispectral image was carried out through TNT Mips spatial software. On the basis of RGB grey values, pixels properties and their digital correlations, results showed that there was a clear cut gap in grey values of colours in the images 1, 2, 3, 4,10,11,14 and 16. Ranges of soil pH and pH index values were 7.30-7.50 and 0.0070-0.0261, respectively in deep brown colour. Similarly, soil pH range varies from 6.80-7.04 and 5.58-6.58 in light yellowish and greenish colour respectively while their corresponding pH index values were 0.0071-0.0451 and 0.0084-0.0239. Thus soil pH range varies from 7.30-7.50, 6.80-7.04 and 5.58-6.58 in deep brown colour, light yellowish colour and greenish colour respectively.

Abstract : Surface modified nano-zeolite (SMNZ) was used as carrier to develop nano-zeolite based nano-sulphur fertilizer. A laboratory study on sulphur nano-fertilizer and conventional sulphur fertilizer were studied with percolation reactor system to evaluate the slow release of sulphur from both fertilizers in ambient temperature. SMNZ and sulphur nano-fertilizer were characterized using Fourier Transform Infrared Spectroscopy (FT-IR), Zeta Analyzer, Raman Spectroscopy, XRD and Scanning Electron Microscope (SEM). Raman spectroscopy confirmed the sulphur attachment at 480 cm-1 in the SMNZ. The FTIR spectra at 1030 cm-1 confirmed the sulphate attachments in the SMNZ spectrum. Zeta analyzer showed the surface charge of sulphur nano-fertilizer had (-) 52.6 mV. SEM imaged the sulphur loaded SMNZ in irregular flake like structure. A comparative study of the release of sulphate (SO4 2-) from fertilizer-loaded SMNZ and (NH4)2 SO4 fertilizers were performed using the percolation reactor. The results showed that the SO42- supply from fertilizer-loaded SMNZ was available even after 912 h of continuous percolation, whereas SO42- from (NH4)2 SO4 was exhausted within 384 h. These properties suggest that SMNZ has a great potential as the fertilizer carrier for slow release of SO42-.

Abstract : Silkworm Bombyx mori L. is prone to be attacked by pathogen and more notably Beauveria bassiana L. Bed disinfectant Kavach was inoculated in different dosages (0.2%-1.6%) to IV and V instar silkworms of both bivoltine and cross breeds. Potency of disinfectant was assessed for the parameters such as survivability, larval duration, physiological, chemo and bio-assay tests. It was revealed that, bivoltine (NB4D2) silkworms were highly susceptible to diseases compared to cross breeds (PMxNB4D2). In bivoltine silkworms, survivability was found to be 61.15% at 1.6% of Kavach, when dusted twice during IV and V instar and crossbreed silkworms exhibited better resistance of 63.10% with the same treatments. Kavach treated silkworms showed decreased larval duration compared to control worms. Crossbreed silkworms were capable of maintaining high level of soluble proteins in spite of infection on 3rd day (17.40%), 4th day (20.50%) and 5th day (21.55%) whereas in bivoltine silkworms soluble protein level was brought down on 3rd day (19.30%), 4th day (22.40%) and 5th day (23.40%). Total soluble sugars varied from third day till fifth day in both the races. Kavach dusted twice at 1% proved to be very useful in the improvement of various commercial cocoons characters.

Abstract : The present investigation was aimed to assess the effect of different concentrations of elicitors viz., salicylic acid (SA) and benzothiadiazole (BTH) on physiomorphological and biochemical parameters of Brassica juncea and B. napus cultivars. The field experiment was conducted during 2012-13 at Punjab Agricultural University, Ludhiana, India. Four different treatments of elicitors and a fungicide treatment were given to 10 week old plants up to four consecutive weeks. Content of total soluble protein, free amino acids, total sugars and reducing sugars of leaves of both B. juncea and B. napus were evaluated after each spray. The content of total soluble protein increased, whereas the contents of free amino acids, total sugars and reducing sugars decreased in all the treatments after each spray. Among all the treatments, the combinations of elicitors, i.e., BTH (3 ppm) + SA (33 ppm) and BTH (7 ppm) + SA (17 ppm) exhibited maximum contents of total soluble protein, free amino acids, total sugars and reducing sugars than control in both the cultivars. These treatments were more pronounced in increasing plant height, internodal distance and number of pods per plant in both the cultivars. Our results suggest that the combinations of elicitors act synergistically to promote growth and metabolic activities in B. juncea and B. napus cultivars leading to the induction and regulation of disease resistance.

Abstract : Biosorption processes have the potential to decrease environmental hazards through their factors such as initial metal ion concentration, temperature, pH and biomass concentration in the solution. In the present study biosorption process was performed using the strains of Bacillus spp. PPS 03 (KF710041) and Bacillus subtilis PPS 04 (KF710042) isolated from sediment core of Paper mill effluent (PME) for the removal of Zn2+and Pb2+ in an indigenously designed Bench-top Bioreactor. The temperature, initial pH, biomass and incubation period of PME for Zn2+ and Pb2+ reduction was standardized. The strains exhibited significant reduction in Zn2+ and Pb2+ of PME to the extent of 73.29% and 85.64% with PPS 03 and 78.15% and 87.57% respectively with PPS 04 after 120 hrs of aerobic treatment. The reduction in the metals occurred from first day of the treatment, but the maximum reduction in these metals was observed after 120 hrs. at pH (7.0±0.2), temperature (35±1.0°C) and biomass (5% v/ v) of the bacterial strains. The removal of metals with strain PPS 04 was more in comparison to the strain PPS 03. The Freundlich isotherms on the data showed that it was linearly fitted for Zn2+and Pb2+. The values of correlation coefficient (R2) of Freundlich isotherms were greater than 0.812 for Pb2+ and Zn2+. The kinetic study for the rate of removal of Pb2+ and Zn2+ by both species was found to best fit a Pseudo first order reaction. The rate constant was found to be inversely proportional to the concentration of parameters. Thus, the microbial strains were found efficient for the biosorption/removal of Pb2+ and Zn2+.

Abstract : In the present experiment, an attempt was made to assess the genetic risk of low dose radiations in mammals. For this purpose female Sprague Dawley rats, 11-12 weeks old, were irradiated with whole body Co 60 gamma rays in three fractionated doses of 0.10 Gy (cumulative dose 0.30 Gy) given at an interval of one month at two different dose-rates (0.00368 Gy/min. and 0.0589 Gy/min.). Ovaries were studied for quantitative evaluation of follicles at 1, 4, 12, 28 and 52 weeks after last fractionated exposure. Quantitation revealed lower number of ovarian follicles in irradiated animals than in controls. The follicular number decreased with the advancement of time after last exposure (i.e. 2 months) and reached a peak level on 28 weeks. After that the recovery was evident but the number remained below 25% of total follicles even at 52 weeks autopsy interval, which indicated an irreversible damage in ovarian tissue. Primary follicles were found to be the most radiosensitive among the various types of follicles. The highest loss in these follicles was noted at 12 weeks after exposure with the high dose-rate, where only 10.61% of them were scored. Dose-rate exhibited an inverse relationship with the number of surviving follicles. At the higher dose-rate (0.0589 Gy / min.), depletion in the total follicular number was significantly higher than at the low dose-rate (0.00368 Gy/min.) used.

Abstract : Field trials were conducted to evaluate the acaricidal potential of entomopathogenic fungus, Beauveria bassiana and aqueous extracts of Withania somnifera and Glyccirrhyza glabra against the mobile stages of Tetranychus urticae Koch on cucumber. The treatments responded in a concentration dependent manner. Highest reduction in T. urticae population was achieved with Omite (0.05%) followed by Nimbecidine (5ml/l), B. bassiana (1010 spores ml-1), W. somnifera (7.5%), B. bassiana (108 spores ml-1), G.Glabra (7.5%), G. Glabra (5%), G. Glabra (2.5%), W. somnifera (5%) and W. somnifera (2.5%). Higher yield was recorded in all the treatments as compared to control. In terms of percent increase in yield, Omite caused highest increase (23.65% over control) followed by Nimbecidine, B. bassiana (1010 spores/ ml), W. somnifera (7.5%), B. bassiana (108 spores/ ml), G. Glabra (7.5%), W. somnifera (5%), G. Glabra (5%), G. Glabra (2.5%), and W. somnifera (2.5%) showing 13.97, 11.82, 10.75, 8.67, 8.67, 8.6, 6.76, 6.48 and 6.45 percent increase over control, respectively. These data suggest that the tested biorationals at higher concentrations have the potential to be employed in pest management programs designed for T. urticae control.

Abstract : The studies to manage the honey bee bacterial European foul brood ( EFB) disease caused by Melisococcus plutonius and ectoparasitic brood mite disease caused by Varroa destructor in the colonies of Apis mellifera (L.) at different locations of Uttarakhand were conducted during 2012- 2013 by applying eco-friendly formulations i.e. spraying of cow urine (desi cow breed), plant decoctions prepared in cow urine, cow dung cake and cow dung ash powders , ajwain seed powder and compared to an antibiotic, terramycin sugar syrup and synthetic chemicals, sulphur and thymol powder with two applications in a month. The data revealed that the cow urine sprays @ 50, 75 and 100% reduced the disease infection to below detectable limit in 10 to 14 days, respectively, as terramycin treated infected colonies where only 50-55% recovery was seen in EFB infection with highest sealed worker brood areas ( SWBA) in cow urine treated honeybee colonies in comparison to terramycin and untreated colonies. Similarly, on the other hand, cow urine (100%) significantly reduced brood mite infestation (72.10%) with highest mean mite fall (48.73) and highest (SWBA) (854.00 cm2) followed by ajwain powder with reduction in brood mi te infestation(65.84%) with mite fall (46.39) and SWBA (749.00 cm2), cow dung powder with reduction in brood mite infestation (71.35%) ,mite fall ( 42.87), SWBA (682.33 cm2), , followed by cow dung ash powder, cow urine @ 25%, in comparison to plant decoctions prepared in cow urine, synthetic chemicals i.e. thymol and sulphur powder after 4 weeks of treatments. Thus, the animal origin products and ajwain powder can serve as a potential eco- friendly measure for management of honeybee diseases in A. mellifera colonies at different locations of Uttarakhand as they significantly increased sealed worker brood area without affecting the activities of workers, queen bee and bee brood in comparison to chemicals and plant decoctions.

Abstract : Dairying at the household level is largely the domain of women. They are contributing for more than 90% of household activities. In livestock management activities, males are contributing only about 10% in form of fodder arrangement, livestock management such as, vaccinations, artificial insemination and selling milk. Considering women’ participation in dairy production system, their different needs and widening gaps the need was felt to have a study on this aspect. The paper describes rationale and importance of the participatory rural appraisal (PRA) approach. The methodology involves the following sequential components: site selection, site description and categorization, planning for PRA, diffusion of results. In this paper, the planning and implantation of integrated interventions have been made to assess women empowerment in dairy production system and improve dairy productivity. The Neeli ravi breed of buffalo was giving higher yield of milk (average 8 liters per day) over the indigenous breed (average 6-7 liters per day). Among the cow the cross bred was giving an average milk yield of 10 lt/day which was more than the 5-6 lt/day given by the indigenous breed. The occurrence of diseases was mainly June to September and the management practices were carried before their onset in May-June only. But, it should be carried out throughout the year for various diseases. The matrix ranking of technology adoptions for buffalo breeds were found to be 34 points against the 26 points for the indigenous breeds.

Abstract : Edible seeds of forest tree crop may be unavailable in sufficient quantity for tree planting projects and so there is need for storage. The germination response of Treculia africana seeds to storage method, duration and moisture content was investigated. Three storage methods were used namely; open basket, jute bag and air-right bottle. Moisture content over time under the storage regimes was investigated for five weeks while the storage aspect was monitored for 20 weeks. The experimental layout was completely Randomized design with three treatments and three replications. Data was analysed using one way ANOVA at 5% level of significance. Fresh seeds had 100% germination. After first week of storage, this valued decreased to 73.3% and 83.3%, and drastically reduced to 3.3% and 13.3% for seeds stored in the open basket and jute bag respectively. The air-tight bottle maintained values of between 93.3-100% throughout the investigation period. There was statistical difference between storage method and duration. The moisture content of freshly extracted seeds was 36.95% and air-tight bottle maintained steady values were between 35.95 – 35.98%; the values for the open basket and jute bag dropped to 18.97 and 20.13% respectively within five weeks and the critical moisture content of < 24.16% was attained in three weeks after which there was no further germination. It is recommended that fresh seeds of T. africana be sown and where long term storage is needed, the air-tight bottle should be used, but resource poor farmers may employ the jute bag to store the seeds for only two weeks if seeds are meant for sowing. Further research is needed in getting appropriate storage devices for large scale storage of seeds for this important crop.

Abstract : Present investigation was carried out to test the effect of time of application on efficacy of Trichoderma harzianum and Pseudomonas fluorescens formulations against bacterial leaf blight of rice, under field condition. Foliar sprays with bioagent(s) in three time sequences i.e. 7 days before, simultaneously and 7 days after inoculation of Xanthomonas oryzae pv. oryzae inoculation significantly reduced disease severity over check during Kharif 2006 and 2007. Maximum reduction in bacterial leaf blight disease was obtained with the application of T. harzianum on 7 days before inoculation of pathogen during Kharif 2006 and 2007 and maximum increase in grain yield was obtained with the application of PBA-2 seven days before inoculation of pathogen. It was revealed that prophylactic spray of bioagents one week prior to pathogen inoculation was significantly (106 cfu/g) effective in reducing disease severity of bacterial leaf blight of rice as compared to chemical treatment.

Abstract : The glands associated with the sting apparatus of worker honey bee Apis florea produce Venom which is known to be composed of a wide spectrum of biomolecules ranging from biogenic amines to peptides and proteins. The Venom apparatus showed the presence of two important associated exocrine glands i.e. Venom gland and Dufors gland. The secretions of both glands are apocrine and are released into the lumen to be stored in the venom sac. The presence of some exocrine cells in the distal part of venom sac which is otherwise known to only store the component of Venom gland led to the present study. The present study that there were considerable differences in the biochemical composition of Venom gland and Venom sac secretions of Apis species The concentration of lipids (Sting gland =1.423±0.0001 and Reservoir = 1.21±0.0067), proteins (Sting gland=0.440±0.0226, Reservoir = 0.390± 0.032), activity of acid phosphatase (Sting gland=112.09±21.100, Reservoir=22.63±1.467) and hexokinase (Sting gland=20.7±4.016, Reservoir=10.66±2.465) was found to be more in case of Venom gland while cholesterol(Sting gland=0.138±0.0161 reservoir=0.324±0.00323), glucose (Sting gland=189±1.31, Reservoir=321±7.19), free amino acids, and activity of alkaline phosphatase (Sting gland=21.03±0.195 Reservoir=22.4±0.685) was more in Venom sac. Glycogen was absent in both Venom gland and Venom sac of Apis species as confirmed by the absence of glucose-6-phosphatase activity. It is established from the present study that Venom sac also secretes various biochemicals and enzymes which are added to the total Venom.

Abstract : The results on the effect of three decade long term application of chemical fertilizers and amendments on the yield of continuous maize-wheat crop rotation in an acid alfisol at Palampur revealed that continuous omission of essential nutrients in a maize-wheat sequence resulted in an appreciable decline in the grain yield of maize and wheat crops. A remarkable reduction in crop yield was noticed in plots where nitrogen was applied alone. Use of recommended level of N alone through urea had deleterious effect on crop productivity. The continuous exhaustion of native pools of K in 100% NP treated plots appreciably reduced percent grain yield. Application of farmyard manure (FYM) and lime along with NPK fertilizers increased the crop yield. The integrated use of optimal dose of NPK and FYM give better and more sustainable yields.

Abstract : The objective of this study was to investigate the osmotic dehydration of Oyster mushrooms in salt-sugar solution at different solution concentrations, immersion times, temperatures and solution to fruit ratio to analyze the water loss, solute gain and weight reduction. Salt-sugar uptake and water transfer were quantitatively investigated during osmotic dehydration of Oyster mushrooms using response surface methodology. Experiments were conducted in a thermostatically controlled agitating incubator. With respect to water loss, solute gain and weight reduction both linear and quadratic effects of four process variables were found to be significant. For each response, second order polynomial models were developed using multiple linear regression analysis. ANOVA was performed to check the adequacy and accuracy of the fitted models. The response surfaces and contour maps showing the interaction of process variables were constructed. Applying desirability function method, the optimum operating conditions were found to be: solution temperature – 42.3°C, immersion time – 44.21 min, salt-sugar concentration – 15 %: 52.57° B and solution to fruit ratio 4.99:1. At these optimum values, water loss, solute gain and weight reduction was 41, 2.15 and 38.6 (g/100 g initial mass) respectively.

Abstract : The present study was undertaken to investigate the kinetics of transformation process of applied and native Zn as influenced by soil moisture regime, available moisture and organic matter additions in Aridisols of western Rajasthan. The incubation experiment was conducted with exact amount of the soil samples (250 g), put in a number of small containers, made of corning glass. Three levels of moisture regimes i.e. field capacity (W0), continuous submergence (W1), alternate submergence and saturation (W2) and two levels of organic matter as starch at 0 per cent (M1) and 0.5 per cent (M2) of the soil weight; and two levels of zinc i.e. native (N) and applied (A) (Zn @ 5 mg kg-1 soil as ZnSO4.7 H2O). The soils then incubated for 30, 60 and 90 days. Destructive sampling was done after each incubation period, and then different fractions of Zn were sequentially extracted by different extracting solutions and determined with the help of atomic absorption spectrophotometer. Based on the results, it can be concluded that the transformation of Zn is largely controlled by organic matter, moisture regimes and Zn application due to considerable changes in the chemical and electrochemical properties of soil and thereby influence the transformation of zinc. Organic matter application significantly increased Zn fractions due to the retention of Zn on exchange complex owing to producing organic acid by decomposition of organic matter in soil. Further, the results showed that if such condition was maintained in the field, and it increased the availability of Zn for different crops in Aridisols.

Abstract : The sorption of diesel, lubricant and castor oils onto different parts (root, stem and leaf) of the dry biomass water hyacinth was studied at the laboratory scale. The parts of the aquapyte water hyacinth (Eichhornia Crassipes) were characterized by physico-chemical methods and the characteristics were used to elucidate the oil sorption process. Hydrophobicity, wettability (capillarity), buoyancy and sorption capacity of oils in the presence/ absence of water were studied to evaluate the suitability of the sorbent for application. In all the three sorbents, the oil sorption capacity increases with the increase of oil film thickness. However of the three parts, the stem has a greater sorption capacity of 9.3, 7.8 and 11.08 g/g for the three oils such as diesel, lubricant and castor oils respectively, even though the root of water hyacinth showed a higher hydrophobicity and surface area. These sorption capacities are comparable with widely used commercial oil sorbent such as nonwoven polypropylene which has a sorption capacity in the range of 10-16 g/g.

Abstract : Watersheds are natural integrators of hydrological, biological, and geological processes and as such require an integrated approach to data analysis and modeling, which usually starts delineating accurately a polygon vector layer of watershed boundaries as input. In that way, Garrah sub-watershed in Shahjahanpur district of U.P., India, had been isolated with the objective of evaluate the accuracy of sub-watershed boundaries derived from three different sources: One was delineated by 2.6 m resolution CARTOSAT-1 DEM (IRS-P5) and other two were derived from a 30 m ASTER DEM and a 90 m SRTM DEM, using the Soil and Water Assessment Tool (SWAT) model. In this analysis we found that the accuracy of CARTOSAT-1 DEM is so best for accurate delineation of a sub -watershed in the management of the watershed, and the coarse spatial resolution SRTM DEM (90 m) performed much better and significantly than the high spatial resolution ASTER DEM (30 m) it’s cause of the errors in the ASTER DEM, map algebra was used to define where the “Fill” tool had filled the sinks finding that the errors in the stream network occurred where some especially large fills had occurred. Not only the visual interpretation of the produces figures indicate the SRTM DEM delineated sub-watershed as relatively more accurate from ASTER DEM delineated sub-watershed boundaries, also statistics for the SRTM DEM elevation turned in significantly higher than that of the ASTER DEM. Overall SRTM DEMs offer more precise elevations while, ASTER DEMs offer more details. Therefore, the accuracy of the sub-watershed delineation depends on the first place on the accuracy of the DEM.

Abstract : Field trials were conducted to assess the damage potential of two-spotted spider mite (Tetranychus urticae Koch) on cucumber (Cucumis sativus Linnaeus). Young cucumber plants were artificially infested with different densities of T. urticae (5, 10, 15 and 20 mites/ grown up leaf) while uninfested plants acted as control. Post infestation, the plants differed in their support to mite density in accordance with initial infestation density and observation period. Grown up leaves were found to be the most susceptible to mite infestation (5.86 mites/ sq. cm leaf). The number of feeding (chlorotic) patches on cucumber leaves significantly increased from 1.38/sq cm at a pre -count of 5 mites per grown up leaf to 1.71/sq cm leaf at a pre-count of 20 mites as compared to no patch recorded in control. Highly significant negative correlation was recorded between mite population and photosynthetic pigments. Total chlorophyll, chlorophyll-a, chlorophyll-b and carotenoids decreased to a maximum of 40, 43.63, 45.45 and 47.27 percent at the highest infestation density as compared to control. Results revealed differences among various treatments in terms of yield attributes of cucumber. The percent reductions from 6.15 to 12.42 in number of fruits, 0.59 to 1.56 in fruit length and 0.93 to 3.28 in fruit width at different inoculums of T. urticae were recorded over uninfested plants. The cumulative effect led to the ultimate reduction in average fruit weight in the range of 10.16 to 17.19 per cent in the infested plants.

Abstract : Long term fertility experiment (LTFE) under double rice cropping system was investigated in Tamil Nadu Rice Research Institute, Aduthurai, India with two varieties (ADT 43 and ADT 45) in two seasons (Kharif and Rabi) under six fertilizer treatments to study the heavy metal accumulation in soil and its impact on paddy. There was a significant variation in physico-chemical properties of soil due to different fertilizer treatments. The surface soil (0-15cm soil depth) in all the treatments showed relatively higher heavy metal accumulation than subsurface. In the long run, there was a build up in the total heavy metal content in soil and it was found to be relatively high in phosphatic fertilizer applied treatments than others. Total Cd and Pb was found high, but the availability was below detectable limit indicated that Cd and Pb were found in unavailable forms, while Cu and Zn were slightly in mobile forms which had been translocated into grain and straw of paddy. The DTPA (Diphenyl Triamine Penta Aceticacid) extractable Cd and Pb in the soil was low, but there was heavy increase in Cu and Zn comparing with initial period. The rate of increase in Cd and Pb content was lower in N alone and control plots. This might be due to the long term application of phosphotic and zinc sulphate fertilizers. Cd and Pb were evenly distributed at low concentrations in grain and straw under various treatments. In case of Cu and Zn, it was relatively higher in grains and paddy straw among various fertilizer treatments. There was no significant difference among the varietal (seasons) treatments for the accumulation of heavy metals in grain and straw.

Abstract : The present investigation was conducted for mass multiplication of Jatropha curcas L. through axillary bud culture. For this nodal segment from 3-5 months old nursery grown plants were used as explants for axillary bud culture. The sterilization treatment involving dipping explants in 0.1 per cent HgCl2 solution for 5 minutes resulted in minimum contamination and maximum establishment of nodal explants. The treatment MS medium supplemented with 1.0 mg/L BAP and 1.0 mg/L IAA was the best for culture establishment, shoot proliferation and multiplication of the axillary buds which exhibited highest value in each parameter like establishment (76.1%), number of days taken for shoot initiation (3.1 days), length of longest shoot (6.8 cm), number of leaves on main shoot (7.1) and number of shoots per explant (6.3). Among different treatments for root initiation, half MS media fortified with 1 mg/L IBA, 3 mg/ L NAA and 0.25 g AC gave best result in maximum number of rooting percentage (60) with minimum time taken for root initiation (13.3 days), produced maximum number of roots per shoots (5.1) and length of longest root (4.9 cm) when established shoots were treated with it. Such produced plantlets showed nearly cent per cent survival after hardening and acclimatization. It showed that explants surface sterilized with 0.1 per cent HgCl2 solution for 5 minutes inoculated in MS medium supplemented with 1.0 mg/L BAP and 1.0 mg/L IAA and half MS media fortified with 1 mg/L IBA, 3 mg/L NAA and 0.25 g AC were best in shoot establishment and root development respectively for mass multiplication of J. curcas L. through axillary bud culture.

Abstract : This research aims to study the communication behaviour of the agricultural input users or farmers in order to find the deficiencies in this field with expectation to highlight the sources of information preferred and extent of extension agency contacts in the areas. Based on this, a strategy can be worked out to disseminate effective agricultural information to the farmers. The communication behavior in this study includes four variables i.e. mass media exposure, extension contacts, source of information and information satisfaction, covering both overt and covert behavioural components. This study was conducted at Udham Singh Nagar district of Uttarakhand state, where two villages namely; Chhinki and Deoria were selected randomly and from these villages, the data were collected with the help of semi structured interview schedule from randomly selected 160 respondents. The findings revealed that the most preferred (61.25%) personal localite communication sources for seeking information regarding agricultural practices were their neighbours or family members followed by local agricultural inputs sellers (13.75%). From personal cosmopolite sources, 51.87 % respondents were preferred to the representatives of the private companies followed by the agricultural university staffs (40%). The majority of respondents (83.75 %) were not associated with any membership in their social system followed by membership (16.25%). It has been reported that even after the sixty six years of independence farmers are still traditionalists, hardliners, shy and ignorant about the agricultural and overall development of the country.

Abstract : This study evaluates the potentiality of an herbal plant Tephrosia purpurea (Linn.) Pers. in the treatment of Letrozole induced polycystic ovary syndrome (PCOS) using female Albino wistar rats. Seed powder of T. purpurea at concentration of 200 mg/kg body weight with milk as a carrier vehicle 3ml/kg body weight, given for at least 3 consecutive estrous cycles. Vaginal smear, FSH, LH, Testosterone, and Estrogen were analyzed to determine the fluctuations in sex steroid level in PCOS induced rats. The plasma testosterone and estrogen level were found to be significantly increased in rats with PCOS whereas Follicle stimulating hormone and Leutinizing hormone did not show any changes. When compared with control the PCOS induced rats showed characteristic ovary with high incidence of ovarian cyst. All the parameters assessed were significantly improved after the treatment with T. purpurea and achieved level close to 80% normalcy. Effect of T. purpurea significantly reduced histopathological changes in ovary and endocrinological and biochemical changes induced by hyperandrogenism. Further to check ovulation and fertility female rats were mated and pregnancy was confirmed. Thus potential of T. purpurea in the treatment of PCOS using an animal model suggested being a good alternative therapy in the treatment of PCOS.

Abstract : A study was carried out to analyze the rainfall data for storage and irrigation planning under humid south-eastern region of Rajasthan using a time series record for 32-year (1980-2011) periods. It was observed that most of the years under observation were having adequate rainfall for all round the year crop production provided the water were collected during the rainy season. The area received 921.5 mm annual rainfall out of which 92% occurred during southwest monsoon (June-September) season. Of the total study period of 32 years, 19% were drought years, 66% were normal years and the remaining 15% were the abnormal years. The annual rainfall during the period showed negative trend (-6.955 mm/year). It showed decreasing trend (-7.782 mm/year) during the month of August and positive trends with 0.864, 3.909 and 1.192 mm/year, respectively, during month of June, July and September. The analysis generally showed that water deficit appeared during the period of November up till May and rain water was excess during the period of June up till September. During these months, rain water can be stored with the help of rainfall harvesting system. If only 50% of total rain water is collected, it forms approximately 44.16 lacs litres of water on a unit hectare basis of land. This rainfall water will be adequate for all rounds the year crop production with conservation of rain water and judicious use of rain water resources.

Abstract : The study was carried out to develop retail cuts, evaluate the effect of the method of pelage (removal/ scalding) on the yield and organoleptic quality of smoked grasscutter (Tryonomys swinderianus). Sixteen grass cutters were purchased from Abico bush meat market in Benin City, Nigeria. The pelages were removed by water and fire scalding. Some were brined in 15% salt solution for 3 hrs while others were not. The carcasses were cut into seven retail cuts. All samples were smoke-dried for 6 hrs. Sensory evaluation was done by a 12-man panel using a 5-point hedonic scale. The results showed that there were significant differences (P<0.05) in the yield of fresh salted and non-salted grass cutter samples. There was also significant difference (P<0.05) in the smoked yield of salted smoked grasscutter with WSS giving the highest yield of 1.03 kg. The method of pelage removal did not have any significant effect (P>0.05) but there was significant effects in the smoked yields. Sensory evaluation showed significant differences (P<0.05) in the colour, tenderness, juiciness, flavor and overall acceptability. Salted samples had the highest scores all organoleptic properties. It was recommended that further studies be carried out to evaluate the effects of salting and smoking on economic and sensory parameters of other sources of bush meat in Nigeria.

Abstract : A total of 80 diverse germplasm accessions of common bean (Phaseolus vulgaris L.) were collected from 31 different locations known for marginal and risk prone farming systems in remote and hilly areas of North-Western Indian Himalayan state of Jammu and Kashmir. The variability was observed in seed color, shape, size and 100- seed weight. Thirteen colors of bean seeds were represented in these 80 accessions with high predominance of red colored seeds. Cuboid, kidney and oval seed shapes observed were represented respectively in 61.25%, 25% and 13.75% of the accessions. There were significant variations in seed length, width and 100-seed weight being highly significant in the later case. All the three seed size classes (small, medium and large according to CIAT categorization) were represented in the collected accessions. 22.5% accessions have 100-seed weight less than 25g, 53.75% accessions have 100-seed weight between 25-40g while 100-seed weight of more than 40g was recorded in 23.75% of the accessions. Highly positive correlations were found between 100-seed weight and seed length and width and between seed length and seed width. The 80 accessions were grouped in three clusters at a coefficient level of 0.3 with largest cluster of 59 accessions followed by a medium cluster with 20 accessions and the least with a single accession. Grid maps generated through DIVA-GIS software indicated that diverse accessions of common bean in terms of seed size and weight can be sourced from the areas falling in Budgam, Shopian and Kulgam districts of the state. Conservation of this remarkable genetic diversity is recommended for future propagation, breeding and the investigation of the genetic relationships.

Abstract : Recent increases in population growth has created an additional demand for meat in developing countries. Nigeria has the largest population in sub-Saharan Africa, with about 47% of the population residing in the urban areas where the population growth rate is estimated at three times that in rural areas. This suggests a shift in increased food demand from the rural to the urban areas and explains the need to know the demand for meat (which is an important source of nutrient) from different animal sources. This study focused on demand analysis for chicken meat, beef and fish among urban households in Edo and Delta States. The complete demand functions of the various meat types were estimated. The primary data used in this analysis were obtained from a cross-sectional survey of urban chicken meat, beef and fish consuming households in Edo and Delta States. A multi-stage sampling technique was used to select 300 respondents for this study. The Linear Approximate Almost Ideal Demand System was used in analyzing the demand functions of chicken meat, beef and fish. Findings showed that the demand for chicken meat, beef and fish in the study area was so much a matter of own-price, cross-prices and income. The results of the LA/AIDS showed that for the entire sample, chicken had an expenditure coefficient of -0.0007 (p ˂ 0.01). With respect to Edo State, chicken had a budget share of -0.2253, cross price effect of 0.1938 with beef and expenditure coefficient of -0.0006 (p ˂ 0.01, p ˂ 0.05 and p ˂ 0.01 respectively). With regards to Delta State, chicken had a budget share of 0.1939. Chicken had a cross price effect of -0.2790 with beef (p ˂ 0.10), while beef had a budget share of 0.5694, cross price effect of -0.2790 with chicken and expenditure coefficient of 0.1170 (p ˂ 0.01, p ˂ 0.10 and p ˂ 0.05 respectively). It is recommended that production of chicken meat and the other selected meat types should be increased to meet the present demand. Prices of these commodities should be regulated to avoid the erratic price fluctuations and efforts should be geared towards improving the income earning capacity of households so as to enable them demand for these commodities effectively.

Abstract : The data on activity pattern and time budget of Swamp deer (Rucervus duvauceli duvauceli) were collected through instantaneous scan sampling from Dudhwa National Park, Uttar Pradesh, India Diurnal activity pattern of Swamp deer showed marked reduction in resting in winter as compared to summer. In winter resting in adult males showed polymodal pattern with peaks occurring at different hours of the day and continued throughout the day without any break. Feeding of adult females in winter and summer seasons showed a polymodal pattern with peaks occurring at different hours of the day without break. In yearling males feeding and resting was observed to occur throughout the day during winter season with peaks occurring between 11:00 to 12:00 hours. Yearling females showed continuous feeding throughout the day with peaks in different times in both the seasons. The seasonal distribution of activity patterns of the fawns showed that feeding was slightly more in summer as compared to winter. In time budget, of the expenditure on different activities, resting accounted for 63.77% and feeding 24.70%. In both the seasons resting was the major portion of their activity. Analysis showed that in all age and sex categories of Swamp deer in the Dudhwa NP, resting dominated on all other activities. The observation on endangered Swamp deer indicates synchronization in activity only in the feeding in the morning and evening hours and resting throughout the day.

Abstract : Present study was carried out to observe the effect of fungal and bacterial bioagents on total phenolic content in rice leaves pre-inoculated with Xanthomonas oryzaepv. oryzae and on disease severity of bacterial leaf blight of rice. Two commercial formulations of Trichoderma harzianum (PBA-1) and Pseudomonas fluorescens (PBA -2) and four formulations of fluorescent pseudomonads and Trichoderma spp. viz, P. fluorescens (Pf 83, rice leaf isolate), fluorescent pseudomonad (FLP 88, rice leaf isolate), T. harzianum (rice leaf isolate), Trichoderma spp. (isolate 40, isolated from rice field soil) were evaluated. Significantly higher mean value of total phenolic content of rice leaves was observed with the application of bioagent formulations as compared to check (pre-inoculated with X. oryzae pv. oryzae), chemical treatment and healthy plant. Maximum mean total phenolic content (342.22 μl/g) in rice leaves was observed with Pf 83, which was followed by PBA-2 (334.44 μl/g) and T. harzianum (330.00 μl/g). Decrease in disease severity of bacterial leaf blight was observed with the increase of total phenolic content in rice leaves which resulted in increased grain yield and 1000 grain weight.

Abstract : The minor carp, Aspidoparia morar is a benthopelagic fish belonging to the sub-family Danioninae under the family Cyprinidae. It has emerged as the single most dominant species in the river Brahmaputra in Assam. In the present study, 240 specimens were collected from Guwahati and Tezpur in the Brahmaputra River and Silchar in the Barak River to investigate the morphometric and meristic variation among the populations. For this a total of 20 morphometric traits and 11 meristic traits were studied. The mean lengths for most of the morphometric traits were higher for the Barak River except eye diameter, inter orbital length and anal fin length which were significantly higher on the Brahmaputra River, while the post orbital length and pelvic fin length were found to be almost equal. The regressions of standard length with all the morphometric traits except pelvic fin length, pelvic fin base, pectoral fin length, dorsal fin length, anal fin length, pre orbital length, post orbital length, inter orbital length and eye diameter showed significant variation between the rivers. Two meristic traits viz. branched rays in anal fin and gill rakers on the first gill arch also showed significant variation in the samples of the rivers.

Abstract : A study was performed under natural environment to compare heavy metal accumulation in soil and Vigna unguiculata L. (Cowpea) irrigated with five rates of SME viz. 10, 25, 50, 75 and 100% concentrations and DAP treatment (applied @100Kg/ha i.e. 0.7g / per 5 Kg) and control (Bore well water) separately in both the rainy (Kharif) and summer (Zaid) seasons for 90 days. Results revealed that among various concentration of SME and DAP treatment, irrigation with 100% SME concentration significantly (P<0.001) increased Zn (323.07-341.02 %), Cu (371.23-389.04%), Ni (3666.66-4133.33%), Cd (525.00-725.00%), Cr (1444.4-1477.77%) and Fe (224.08-244.89%) in the soil. In case of V. unguiculata irrigated with different SME concentrations, maximum range of heavy metals such as Zn (2.43-2.98 mg Kg-1), Cu (2.39-2.73 mg Kg-1), Ni (0.55-0.91 mg Kg-1), Cr (1.01-1.21 mg Kg-1), Cd (0.13- 0.17 mg Kg-1), and Fe (5.54-6.18) were observed at 100% concentration of SME than that of DAP treatment in both the cultivated seasons. However, the concentration of all the metals Zn, Cu, Ni, Cd, Cr and Fe in soil and plant were lower than toxicity threshold i.e. within the permissible limit. Enrichment factor (Ef) for soil/V. unguiculata was recorded maximum with Ni (37.66-42.33) / (24-30.33) and minimum with Fe (3.24-3.44) / (2.28-2.52) after 90 days of SME irrigation than DAP in both the cropping seasons of Kharif and Zaid. The minimum accumulation of Fe in both soil and crop showed that metals with completely filled d orbitals (d8, Fe) were least incorporated into the V. unguiculata crop.

Abstract : A field experiment was conducted during 2011-12 in an agrisilvicultural system consisting of two silvicultural species viz. Acacia mangium (mangium) and Gmelina arborea (gamhar) planted in 2000 at a spacing of 8m x 2m and four agricultural crops viz. Ananas comosus (pineapple), Aloe vera (aloevera), Andrographis paniculata(kalmegh) and Curcuma amada (mangoginger) were raised in the 1st week of July, 2011.The maximum volume increment were achieved by mangium with pineapple (16.53 m3/ha). Pineapple also registered the maximum fruit yield of 9981Kgha-1 under mangium and minimum under gamhar (9106 Kgha-1). The fresh leave yield of aloevera (8635Kg ha-1) was maximum under mangium which is statistically at par with gamhar. However, kalmegh recorded maximum dry plant yield of 1239 Kgha-1 under open condition followed by 1072 Kgha-1 under gamhar and 823 Kgha-1 under mangium. Similarly, mangoginger exhibited maximum rhizome yield of 3300 Kgha-1 under open condition followed by 1979 Kgha-1 under gamhar and 1597 Kgha-1 under mangium. The trend of crop yield under both the trees and open condition was: Pineapple >Aloevera>Mangoginger>Kalmegh. A. mangium with pineapple based agrisilvicultural system recorded the highest gross return, net return and BCR as compared to other agrisilvicultural systems and sole crops.

Abstract : The present investigation observed the effect of current density (CD), operating time (OT), inter electrode distance (IED), electrode area (EA), initial pH and settling time (ST) using Al-Al electrode combination on the removal of color, total suspended solids (TSS), hardness (HR) and alkalinity (ALK) from biologically treated municipal wastewater (BTMW) of Sewage Treatment Plant (STP), Jagjeetpur, Haridwar, India. The maximum removal of color (99.86%), TSS (98.7%), HR (78.9%) and ALK (43.69 %) from BTMW was found with the optimum operating conditions of CD (2.65 A/m2), OT (40 mins.), IED (0.5 cm), EA (160 cm2), initial pH (7.5) and ST (60 min.). However, the maximum removal of ALK was found with the optimum operating conditions of CD (1.68 A/m2), OT (40 mins.), IED (1.0 cm), EA (80 cm2), initial pH (7.5) and ST (90 min.) The electrolytic treatment ( ET) brought down the concentration of HR and ALK to the desirable limit of the BIS standards of drinking water. There was no need of pH adjustment of the BTMW during ET as the optimal removal efficiency was close to the pH of 7.5. Under optimal operating conditions, the operating cost was found to be 1.01 $/m3 in terms of the electrode consumption (23.71x 10-5 kg Al/m3) and energy consumption (101.76 Kwh/m3). The study revealed that BTMW can be effectively treated with the Al-Al electrode combination for color, TSS, HR and ALK removal.

Abstract : Arbuscular mycorrhizal fungi are soil fungi distributed worldwide, forming symbiosis with most of the vascular plants for their growth and survival, which is used for sustainable agriculture and ecosystem management. This study investigated the establishment of monoxenic cultures of Glomus intraradices in association with transformed carrot hairy root. The G.intraradices spores were isolated from sugarcane rhizosphere by wet sieving and decanting technique and propagated in open pot culture. Transformation into carrot hairy root was done using Agrobacterium rhizogenes. Surface sterilization of G.intraradices spores co-cultured with transformed carrot hairy root in Modified Strulla and Romand (MSR) medium was found the host root growth as well as for germination AM spores. After three months of incubation in dark condition, significant production of extensive hyphal growth on MSR medium and an average of 8500-9000 spores per petri dish was observed. The in vitro inoculum exhibited higher potential of root colonization due to numerous intraradices mycelium with extensive spore load. The produced monoxenic inoculum can be used in place of traditional system where it has an advantage of producing contaminant free propagulas. Thus the monoxenic culture system, a powerful tool, of AM sporulation, can be used for the mass production of monoxenic inoculum of AM fungi besides studying its biology.

Abstract : The present study was carried out to investigate the comparative seasonal distribution and relative abundance of fish fauna of streams Bachan Gad of river Alaknanda and Kakda Gad of river Mandakini of Mid-himalayan Ganga river System. Total length of the Bachan Gad is 14.5 km from origin to the confluence at main river Alaknanda with an altitudinal variation from 605.94 to 1418.23m (a.s.1), whereas, total length of the Kakda Gad is 15.5 km. from origin to confluence at main river Mandakini with altitudinal variation from 984.50 to 1993.70 m (a.s.1). Total 23 species from Bachan Gad and 20 fish species were identified from Kakda Gad. The differences in the availability of fish-fauna were directly related to the nature of the profile and slope of tributaries; which affects the migration and breeding grounds of the fishes inhabited in the main river Alaknanda and Mandakini of Ganga river system. Variation in the availability of fishes has been recorded from different sites of the stream. In streams and rivers the changes take place along their length is directly related to the eco-physico-chemical nature (water depth, current, substratum etc). All these factors which change along the length of streams are also the factors which control the distribution of the various sections of the biotic fauna and flora.

Abstract : Interactions between mathematical and biological sciences have been increasing rapidly in recent years. The use of system analysis and mathematical model for formulation and solving the environmental pollution is of relatively recent vintage and has been used widely since last three decades. These models can be used to conduct numerical experiments, test hypothesis and help to understand the response of environmental pollution. A mathematical model acts as a bridge between study of mathematics and application of mathematics in environment and other fields. Modeling is an abstraction of reality and its ultimate objective is to explore the complexity of functions and structure of the system under study. Today, a wide variety of models belonging to different nature and category are available to understand the processes of the environment around us. Various models such as WASP, CE-QUAL-ICM, QUAL W2, AQUATOX, QUAL2K, IITAQ, PEARL, GRAM, UGEM, and IITLT etc. related to water and air quality are developed so far along with their principles, intended use and applications. These models generally simulate the basic physical, chemical and biological processes. In the present study, an attempt has been made to evaluate the concept and utilization of mathematical models in air and water quality management.
