Abstract
Soil quality is conceptualized as the major linkage between the strategies for agricultural conservation management practices and achievement of the major goals of sustainable agriculture. Soil biological properties respond quickly and have been suggested better indicators than soil physical and chemical properties which alter only after drastic change in soil quality. Soil biological components occupy only 0.5% volume of soil and usually constitute up to 10% of soil organic matter (SOM). Strategies for improvement in soil biological properties requires understanding of numerous interactions among soil biological community and diversity, climate, soil type, plant species and soil management practices. Organic matter through crop residues at the soil surface, root and cover crops, animal manure, green manure, compost and other sources, improve biological properties of soil. Tillage enhances bacterial growth in the short-term by aerating the soil and by thoroughly mixing the organic matter with bacteria and soil. A single tillage event is generally inconsequential to microorganisms, but repeated tillage eventually reduces the amount of soil organic matter that fuels the soil food web. Cropping systems and crop rotation influence the microbial biomass by putting a different food source into the soil each year. Cover crops extend the growing season and increase the amount of roots and above-ground growth that becomes part of soil. As with other crops, the rhizosphere of a cover crop provides food for bacteria when food sources would otherwise be scarce. Balanced fertilization is in general, promotes the soil microbial counts and biological properties. Inoculation with soil beneficial organisms, such as nitrogen fixing bacteria, blue green algae and mycorrhiza in general have shown to enhance the soil health, plant nutrient uptake, aggregation, soil structure and porosity and heavy metal tolerance. Soil organisms require some specific soil conditions for their growth and functioning e g pH.

Abstract
A field experiment was carried out during Kharif 2014 at AICRP on Dryland Agriculture, University of Agricultural Sciences (GKVK), Bangalore, Karnataka to study the effect of conservation tillage and nutrient management practices on the performance of finger millet and weed growth under dryland Afisols of southern Karnataka. The experiment was laid out in split plot design with three main plots on different tillage treatments and five sub plots with different nutrient management practices. The research outcomes revealed that the significantly lower weed density, dry weight at 30 and 60 DAS and higher finger millet growth and yield parameters resulting in higher grain yield of finger millet was realized in the conventional tillage practices (3202 kg ha-1) as compared to minimum (2758 kg ha-1) and zero tillage (2302 kg ha-1). Among different nutrient management practices, application of 100% NPK + 7.5 t FYM ha-1 has recorded significantly higher growth and yield parameters of finger millet resulting in higher grain yield (3249 kg ha-1) as compared to other treatments viz horsegram residue mulch + fertilizers based on soil test results (2880 kg ha-1), horsegram residue mulch + 100% recommended NPK (2790 kg ha-1) and other treatments.

Abstract
Field investigation was carried out at Zonal Agricultural Research Station (ZARS), V. C. Farm Mandya, UAS, GKVK, Bangalore, Karnataka during 2014-15 to study the effect of fertigation levels and fertigation scheduling on yield, quality and commercial cane sugar production of sugarcane under subsurface drip fertigation. The results of the experiment revealed that fertigation scheduling upto 9.5 months has given on par results on the quality parameters viz brix (19.85%), pol (18.92%), purity (95.42%), reducing sugar (3.30%) and CCS (commercial cane sugar production) (13.65%). Similar results was also observed under fertigation levels upto 125 per cent RDF (recommended dose of fertilizer) recorded quality parameters viz brix (20.26%), pol (19.34%), purity (95.63%), reducing sugar (3.20%) and CCS production (13.84%) and the interaction effect between fertigation scheduling and fertigation levels also followed the same trend recorded quality parameters viz brix (19.80%), pol (18.85%), purity (95.38%), reducing sugar (3.31%) and CCS production (13.60%). In comparison with conventional method of sugarcane cultivation recorded lower quality parameters viz brix (19.72%), pol (18.80%), purity (95.16%), reducing sugar (2.82%) and CCS (13.34%). Significantly higher cane yield was observed under fertigation scheduling upto 9.5 months (250 t ha-1) and higher cane yield (225 t ha-1) under fertigation levels @ 125 per cent RDF. The interaction effect between fertigation scheduling and fertigation levels are significant, the fertigation up to 9.5 months with 125 per cent RDF recorded significantly higher cane yield (255 t ha-1) while conventional method of cane cultivation recorded significantly lower cane yield (146 t ha-1). This clearly indicates that increment in the fertigation scheduling and fertigation levels does not affect the quality and CCS production of sugarcane under subsurface drip fertigation. However, significantly higher cane yield can be obtained under fertigation scheduling and fertigation levels without affecting the quality and CCS production.

Abstract
A field experiment was conducted at Indira Gandhi Krishi Viswavidyalaya, Raipur, Chhattisgarh in inceptisols and vertisols to study the influence of integrated nutrientm on Yield under inceptisols and vertisols planted with rice-wheat cropping system. The design was used by Nested factorial design with 4 replication and 5 treatments: Control (N: 00, P: 00, K: 00); RDF NPK (100:60:40 kg ha-1); YTR 5 t ha-1 (soil test based); YTR 6 t ha-1 (soil test based) and YTR 6 t ha-1 + 5 t ha-1 FYM (IPNS), respectively. The result indicated that the yield of crops showed changes with treatments from T1 to T5 due to different fertilizer doses. As per the increased organic matter by FYM and fertilizer application the highest grain yield (59.10, 59.93 q ha-1) was recorded with the treatment that received the fertilizer dose with FYM to achieve 6.0 t ha-1 rice yields. The grain yields recorded from these two treatments 5 T ha-1 YT (T4), 6 T ha⁻1 +FYM ha-1 YT (T5) (58.07 q ha-1 and 59.10 q ha-1) (58.24 q ha-1and 59.93 q ha-1) were statistically at par. However, these two treatments of RDF were significant by superior than control, (25.28 q ha-1 and 16.79 q ha-1) respectively yield in Inceptisols and Vertisols. The next significantly higher grain yield was found with the application of RDF (100:60:40 kg N: P2O5: K2O ha⁻1) followed by the treatment that received the fertilizer dose for 5 t ha-1 yield target (53.16 q ha-1 6 and 55.75q ha-1) respectively.

Abstract
Brinjal is the important vegetable crop in South Asia and prone to many insect pests. It is susceptible to environmental conditions like severe frost. Among the insect pests, sucking pests like whitefly and jassid cause a severe damage to crop through sap sucking and also act as vectors for viral diseases. Keeping these points in view an experiment was conducted in Banaras Hindu University, Varanasi to study the population dynamics of jassid and its subsequent management with different formulations of fipronil. The results of population dynamics revealed that the activity of jassids started during first week of September 2013 and thereafter population reached to peak by 2nd October 2013 and again rebounded to a peak population of 4.09 jassids during November 2013. However, jassid population showed a significant positive correlation with mean relative humidity (r = 0.558) and mean temperature (r = +0.353). A non significant positive correlation was observed with total rainfall (r = 0.347). Further, insecticides viz fipronil 200SC, fipronil 80WG, fiproni 5SC, fipronil 0.6GR, fipronil 0.3GR, carbofuran 3G and a control were tested for their efficacy against jassid. Among these insecticides, fipronil 200SC was observed to be effective followed by fipronil 5SC, fipronil 80WG.

Abstract
A tractor operated rotary weeder was designed using computer aided design software and prototype was fabricated. The weeder was evaluated for its field performance in cotton crop. The experiments were conducted at three forward speeds (2.0, 2.5 and 3.0 km h-1), with two rotary speeds (210 and 240 rpm) for three different types of blades (L-type, C-type and J-type). The better performance of tractor operated rotary weeder was observed at 2.5 km h-1 forward speed with rotary speed of 210 rpm for L-type blade compared to other types. Results of field performance evaluation showed that the weeding efficiency and plant damage of the weeder were 89.50% and 3.75% with a fuel consumption of 5.5 lh-1 with an area coverage of 0.43 ha h-1. The cost of operation for the weeder was estimated to be Rs.1357 ha-1 as against Rs.2500 ha-1 for conventional method of manual weeding. The breakeven point for rotary weeder was found to be 98 h per annum with a payback period of 2.3 years.

Abstract
In the present study, the seeds of Brassica nigra (variety 1021) were used to study the effect of Fe and Mn on different physiological parameters. The effects of iron and manganese were studied with regard to leaf area and secondary roots of black mustard seedlings under 50, 100 and 200μM concentrations. These concentrations significantly affected the leaf area and secondary roots compared to control. Leaf area significantly increased at all concentration of Fe and Mn while at higher concentration of Fe and Mn (200μM) reduction in secondary roots of seedlings was observed. However, additional supply of the 5mM nitrogen in the form of Ca (NO3)2 in the nutrient medium increased the effect of these metals. On the application of nitrogen in the nutrient medium, Fe showed more promotary effect in leaf area under all concentrations (50μM, 100μM and 200μM) while secondary roots decreased at all concentrations of the Mn.

Abstract
The present studies were carried out during spring seasons of the year 2013-14 and 2014-15.The field studies were conducted at the Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. Seasonal occurrence of natural enemies was recorded at weekly intervals starting from seven days after sowing from 25 selected maize plants. Staphylinid beetles, coccinellid beetles and spiders were found as major predators. Higher number of coccinellid beetles was recorded during third week of March and first week of April in 2013 and 2014 respectively. Spiders were active throughout the season with mean population 1.65 and 2.32 spiders/plant during spring season in 2013 and 2014 respectively. Higher number of rove beetles was recorded in third week of March in 2013 and2014 (7.75 and 14.90 beetles/plant respectively). The lygaeid bug Geocoris was least active predator with seasonal mean of 0.54 and 0.41 per plant during spring season in 2013 and 2014 respectively. Among coccinellid Cheilomenes sexmaculata was dominated with 38.28 and 49.34 per cent in 2013 and 2014, respectively.

Abstract
The data of reproductive traits of Konkan Kanyal goats maintained at Cattle Breeding Farm, Nileli were recorded from 2001 to 2011. The overall average age at first kidding, weight at first kidding and number of kids per kidding in Konkan Kanyal goats were 579.68 ± 4.10 days, 25.61 ± 0.37 kg, and 1.26 ± 0.017, respectively. The effect of non-genetic factors viz year of birth, season of birth and birth weight were significantly affected on age at first kidding, while the type of birth and parity were not significant. The shortest age at first kidding was observed in the year 2006 (543.25 ± 12.13 days), while the significantly longest (612.54 ± 23.48 days) was in the year 2007. The lower age at first kidding in north-west monsoon (NWM) season (551.91 ± 9.52 days), followed by winter (574.62 ± 6.25 days). The significantly higher age at first kidding was in summer season (599.7 ± 8.45 days) and was at par with south-west monsoon (SWM) season (591.24 ± 9.59 days). All non-genetic factors except season of birth showed non-significant effect on weight at first kidding. The weight at first kidding was higher in SWM (28.12 ± 2.18 kg) and lower in NWM (24.31 ± 0.18 kg) season. The year of birth and parity had significant effect on number of kids born per kidding while season of birth, type of birth and birth weight group had non-significant effect. The overall performance of reproductive traits affected by non-genetic factors was found better in high rain fall and warm humid climate region.

Abstract
Xanthium indicum L. is a cocklebur or bur-weed commonly found in roadsides, rice fields and hedges throughout the tropical part of India. Green gram is a rabi crop normally grown after harvesting of rice during winter season. During the months from December to February green gram is cultivated and the same time Xanthium indicum grows in the fields which may affect the field directly and crops indirectly. Basing on above fact, the experiment was conducted in order to evaluate the allelopathic effects of the aqueous leachate of Xanthium indicum L. on the seed germination and enzymatic activities of green gram in laboratory condition. Results showed that leachates of all concentration (5, 10, 15, 20 and 25%) are considerably inhibited seed germination process in green gram. Different concentrations of various types of leachate drastically checked α-amylase and protease activities during seed germination in green gram. From this above results it is noticed that there might have certain allelochemicals in plant and plant parts which are checked or inhibit the enzymatic activities, it ultimately decreased seed germination. Hence, the Xanthium indicum plants should be removed from fields at its vegetative stage.

Abstract
The study was undertaken at Devanahalli taluk, Bangalore Rural district; Karnataka was studied with an objective to classify the irrigation water of eastern dry zone of Karnataka with respect to irrigation quality. The results of the study indicated that majority of the groundwater samples belongs to class C2S1 class, when such water is used for irrigation may pose the problem of salinity especially in soils with poor drainage. Nearly 180 (75.6%) ground water samples before rainy season and 181 (75.1%) after rainy season of all hoblis of Devanahalli are considered safe with respect to RSC class (< 1.25 meq L-1). The RSC of 24.3 and 30.3 percent groundwater samples of Vijayapura hobli before and after rainy season were classified as unsafe for irrigation followed by Channarayapattana hobli (15.7% and 12% before and after rainy season) whereas very few samples of Devanahalli Kasaba (4% and 0.9%) samples before and after rainy season were unsafe for irrigation.

Abstract
A disease screening field trial of rice germplasm consisting of 9 parents, 36 crosses and one local check was established during the kharif 2012 at two sites in Kashmir to determine resistance intensity in rice germplasm against Pyricularia grisea, the cause of rice blast disease. Screening was done under natural epiphytotic conditions and the results revealed that none of the test lines was immune or highly resistant. Four cross and one parent which include SKAU-389 × SR-1, SKAU-389 × K-08-6, SKAU-389 × K-08-60, SR-1 × K-08-60 and two parent K-06-60 and PS-5 were found to be resistant against blast. Six crosses and two parents were found to be moderately resistant. Rest of crosses and parents behaved either moderately or fully susceptible to blast disease. Among these two sites MRCFC Khudwani was identified as a better site for screening rice genotypes for blast resistance than KVK Pombay.

Abstract
Brassica juncea is an important oilseed crop of India. It is susceptible to various biotic stresses which hinder their yield potential. The mustard aphid (Lipaphis erysimi) is the most devastating insect and causes severe yield losses throughout mustard growing areas. Plant lectins are carbohydrate-binding proteins and have a role in plant defense against insects including aphids. Transgenic Brassica juncea plants carrying pigeonpea lectin (CCL) gene driven by phloem specific rolC promoter were generated using Agrobacterium-mediated transformation. The cotyledonary petioles, hypocotyls and stem segments were used as explants. The transformation efficiency was found to be 18.32%, 6.18% and 34.69% respectively. The molecular analysis by PCR and RT-PCR using CCL and NPTII gene primers confirmed the integration and expression of the transgene. In future, these transgenic plants can be used for aphid bioassay to demonstrate its efficacy against Lipaphis erysimi and for production of marker free transgenic mustard.

Abstract
Rice being the most important staple food in India plays an important role in economic stability of India. An insight of genetic diversity and correlation among the various traits related to yield and quality is helpful in this regard. Seventy rice genotypes were evaluated for genetic variability and correlation. The experiment was conducted in the research area of Regional Agricultural Research Station, Jagtial, Professor Jayashankar Telangana State Agricultural University, Telangana following randomized complete block design with three replications. The data were recorded on yield and different yield and quality components. The analysis of variance revealed highly significant differences among all genotypes for all the yield and quality traits. Plant height, number of productive tillers per plant, panicle length, number of filled grains per panicle, kernel breadth and 1000-grain weight had a highly significant positive phenotypic correlation with grain yield per plant. The study of path analysis for yield and quality related traits revealed that 1000-grain weight, number of filled grains per panicle, number of productive tillers per plant, days to 50 percent flowering, plant height, panicle length, L/B ratio and milling percentage had positive direct effect on grain yield per plant, indicating that the selection for these characters was likely to bring about an overall improvement in grain yield per plant directly.

Abstract
A field experiment was conducted during early kharif, 2013 at Regional Agricultural Research Station, Tirupati with fourteen pre release and two released groundnut genotypes. The present investigation revealed existence of sufficient genetic variability among the genotypes tested for Water Use Efficiency, heat tolerance and Relative Water Content. The WUE traits i e Specific Leaf Area (SLA) from 157.38 to 201.56 cm2 g-1, SPAD Chlorophyll Meter Reading (SCMR) from 39.07 to 46.75 varied among the genotypes. Similarly among the heat tolerance traits i.e., relative injury of cell membranes revealed mean variability of 10.08 to 17.78 % and Chlorophyll Stability Index ranged from 32.25 to 69.75%. The genotypic variability for relative water content was 83.14 to 92.61%. During early kharif 2013, moderate SLA with high SCMR, recorded higher pod yield in groundnut. Cultivars TCGS-1330, TCGS-1375 posses moderate SLA and higher pod yield compared to checks. Moderate SLA and high SCMR possessing genotypes TCGS-1330, TCGS-1375, TCGS-1157A, TCGS-1157 were promising for higher WUE, which can be explored in developing cultivars for higher WUE. Genotype TCGS-1375 recorded high CSI, moderate Relative Injury (RI) and high pod yield. Other genotypes TCGS-1350, TCGS-1173, TCGS-1349, TCGS-1157 possess heat stress tolerance with moderate yields. Hence genotypes TCGS-1330, TCGS-1375 recorded high values for physiological traits, possessing high WUE and high yield are suitable for early kharif situation.

Abstract
Thirty six soybean genotypes were evaluated for their morphological traits and the extent of genetic variability. Analysis of variance revealed that the genotypes were highly significant for all the characters studied, indicating the existence of considerable magnitude of variability. The higher value of PCV, GCV, h2 and GAM for the traits like plant height (cm), primary branches plant-1, clusters plant-1, pods plant-1, seed yield plant-1 (g) and seed yield hectare-1 (q) indicating the predominance of additive gene action and can be improved through direct selection. Mahalanobis D2 analysis suggested the maximum contribution of seedling vigour index- I towards divergence, followed by plant height and seed yield hectare-1. All 36 genotypes were grouped into 13 clusters, of which cluster I was large with 17 genotypes. Based on mean performance, two genotypes from cluster XII (EC 16213 and PS 1418), one from cluster XI (TG X 814-14B) for seed high yield hectare-1 and cluster II (JS 2089) and cluster XIII (PS 1042) for germination after accelerated aging were found superior and can be used in the future breeding programmes.

Abstract
In this study we have investigated the effect of irradiation on post harvest quality of garlic and to determine the irradiation dose for maximum quality retention during storage. Two varieties of garlic, namely, Yamuna Safed (G-1) and Yamuna Safed-4 (G-323) were analyzed for their physical and physico-chemical composition for observing the efficacy of different doses of irradiation (0.075 kGy, 0.1 kGy and 0.15 kGy) for their storage study from 120-210 days after harvest at ambient temperature (18 - 32°C and 55 - 65% RH). Effect of irradiation on physical, physiological and biochemical parameters during storage of both the varieties of garlic revealed that overall 0.1 kGy irradiation dose was most successful followed by 0.15 and 0.075 kGy for checking sprouting, physiological loss in weight (PLW), respiration rate and retention of pyruvic acid, and amylase activity during storage in comparison to non-irradiated samples. Among two varieties studied, variety G-323 performed better than G-1 with regard to changes in physiological and biochemical parameters during storage.

Abstract
Composting emerges as the most widely applicable process for handling diverse wastes in the entire area of waste recycling. Organic wastes are composted in an appropriate manner depending on their physico-chemical nature to mitigate the environmental consequence of direct land application; composting also helps to meet the demand of organic manure for intensive farming. A very wide variety of organic residues from sources of plant, animal and industrial wastes can be composted to evolve a stable eco-friendly product of utility. Lot of waste materials such as tree litter, coffee, tea wastes and vegetable wastes etc are available in and around Nilgiri hills of Tamil Nadu. A laboratory experiment was carried out to standardize biocomposting technology for waste materials viz albizia, teak litter, pungam, simaruba shell, coffee, tea processing and vegetable wastes. In order to find out the efficient waste management technology, the selected waste materials were subjected to both conventional and vermicomposting processes. The data on the population of different microbial groups revealed that vermicomposts harboured more number of microbes. Vermicompost obtained from coffee pulp ranked first interms of microbial population. Studies on soil dehydrogenase revealed a significant positive correlation between microbial population and the enzyme activity. Accordingly vermicomposted coffee pulp recorded greater enzyme activity. Similarly nitrogen fixing free living diazotrophic microbes such as Azotobacter, Azospirillum and Beijerinckia were greater in vermicomposts. But the content varied with the substrate. Coffee pulp had greater number of Azospirillum, simaruba shell registered more value for Azotobacter and Beijerinckia was maximum due to pungam shell compost. On the contrary, the phosphate solublizing microbial population was maximum in conventional composts. Among acid and alkaline phosphatases, alkaline phosphatases scored more value. Vermicomposted albizia litter recorded more of IAA.

Abstract
A field experiment was carried out to study the effect of treated and untreated domestic wastewater and fertilizer levels on yield and quality parameters of tomato during 2014 at the Main Agricultural Research Station, University of agricultural Sciences, Dharwad. The experiment comprised of four irrigation sources (I1- treated domestic wastewater, I2- fresh water, I3- untreated domestic wastewater alternated with fresh water, and I4- untreated domestic wastewater) and four fertilizer levels (0, 50, 75 and 100% RDF). The results revealed that, among irrigation sources significantly higher yield and quality attributes were noticed with application of either untreated or treated domestic wastewater as compared to application of domestic wastewater alternated with fresh water and application of fresh water alone. Increase in fruit yield was 14.53 and 16.39 per cent in treated and untreated domestic wastewater, respectively as compared to fresh water. Among fertilizer levels application of 100 RDF (250:250:250 kg N, P2O5 and K2O ha-1) resulted in significantly higher yield and quality attributes as compared to other fertilizer levels. The magnitude of increase in yield was to the tune of 47.74 per cent with application of 100 per cent RDF as compared to absolute control. Among interaction effects, application of untreated and treated domestic wastewater along with 100 per cent RDF resulted in significantly higher yield and quality attributes and both were superior over other treatment combinations. The increase in fruit yield was 60.67 and 60.54 per cent with application of untreated and treated domestic wastewater along with 100 per cent RDF, respectively as compared to fresh water application without fertilizers.

Abstract
The genus Lactobacillus is an important dairy starter organism which could play a vital role in maintaining host health by limiting other intestinal microbes causing harmful effects. Using an animal model, we studied the immunomodulatory potential of Lactobacillus helveticus fermented milk (FM) in comparison to Cell Free Supernatant (CFS) and Dahi (D) by measuring intestinal enzymes (β-Glucuronidase (EC 3.2.1.31) and β-Galactosidase (EC 3.2.1.23)) in mice against Salmonella enteritidis. In comparative study Dahi prepared with mixed dahi culture was taken because it has proven and established immunomodulatory effects against infection. Three groups of animals were fed with D (5 gm/animal/day), FM (5gm/animal/day) and CFS (2.25 ml/animal/day) in addition to standard laboratory diet for 7 days. These animals were challenged with 1 × 108 CFU Salmonella enteritidis pathogenic cells by intubation. The β-Galactosidase activity in intestinal fluid was highest in Dahi (283.34 nmoles/h/ml) and FM (197.30 nmoles/h/ml) on 5th day post challenge. The β- Glucuronidase activity was found highest in FM (227.88 nmoles/h/ml) on 5th day followed by CFS (237.18 nmoles/h/ml) on 8th day. It was observed that Lactobacillus helveticus fermented milk also shows significant increase in intestinal enzyme activity like Dahi.

Abstract
The quantitative analysis of bacterial flora associated with the skin of freshwater fishes in Udaipur region was determined. Four different types of fishes were catch, identified as Notopterus notopterus, Labeo rohita, Heteropneustus fosillis and Catla-catla from Picchola lake and Fatehsagar lake and brought to laboratory, total bacterial load were calculated on nutrient agar at 37°C by using pour plate method. The highest bacterial load (5.1 × 105 CFU/gm) was found on the skin of Notopterus notopterus and the minimum (4.0 × 102 CFU/gm) on Labeo rohita was recorded. A total 18 bacterial isolates were isolated from all collected fishes for the identification of bacterial species associated with freshwater fishes in Udaipur region. Phenotypic characterization of each isolates was carried out by studying morphological characteristics and carbohydrate fermentation. On the basis of carbohydrate fermentation and phenotypic characters three different pattern obtained. Molecular typing was attempted to find out the similarity or difference in genetic structure of some selected bacteria with the help of 16S rRNA gene amplification and Amplified Ribosomal DNA Restriction Analysis (ARDRA). Near complete 16S rDNA was amplified by PCR from the genomic DNA of each isolate. Following RFLP analysis were done by using two restriction endonuclease enzymes viz EcoRI and Hind III, that produced different cluster were subsequently sequenced one from each cluster and compared with the available gene sequences in NCBI website by using BLASTn. Out of 4 groups, there were 3 different species obtained and sequences submitted to Gen Bank, USA viz Brevibacillus agri (KT320872), Staphylococcus gallinarum (KT320873) and Bacillus cereus (KT320875) showing more than 95% similarity with the GenBank sequences. These findings provide consumers insight into fish quality, probable health risks of raw fish consumption, and the impact of storage conditions on bacterial load of raw fish.

Abstract
The aim of this study to reduces the losses of N and improves NUE, yield and economics by the natural nitrification inhibitors. With the introduction of high yielding varieties (HYVs), the use of chemical fertilizers increased. Maize (Zea mays L.) is veracious consumer of nitrogen fertilizer. When urea applied to soil lost by several processes like leaching, denitrification, runoff, volatilization and nitrification. Among those losses nitrification is most widely occurs under drylands. Inefficient use of nitrogen fertilizers has resulted in low nitrogen use efficiency and reduced yields, adverse ecological and environmental effects contributing to eutrophication, and N2O emissions which are a potent green house gas. Hence arresting these losses the urea coated with several natural compounds neem cake, karanj cake and Vitex negundo leaf powder by using adjuvants like castor oil and coal tar are known for nitrification inhibition, to improve the availability and agronomic nitrogen use efficiency and factor productivity of the crops in terms resulted in increased crop yield and BC ratio.

Abstract
Biology of predatory green lace wing Chrysoperla zastrowi sillemi (Esben–Peterson) was studied on the various natural hosts viz aphids, whiteflies, mealybugs and Corcyra eggs and different artificial food sources viz honey, protinex and mixture of both for a single generation during 2013–14 at the Department of Entomology, University of Agricultural Sciences, Bengaluru, Karnataka. The study revealed that the larval period (8 ± 1.89 days), pupal period (9.13 ± 0.0072 days) was relatively shorter and larval weight (0.00871 g) of C. zastrowii was relatively highest when reared on Corcyra eggs than on aphids, whiteflies or mealybugs. This implies that Corcyra eggs were the better laboratory host for rearing Chrysoperla zastrowii larvae than aphids, whiteflies or mealybugs.

Abstract
Indian aromatic rice is a small group of premium aromatic rice from India, prized in international trade. It is praised for its unique quality aroma, is a connoisuer’s delight, a natures gift to Indian sub continent. The aromatic trait differentiates the highly valued aromatic rice from the other rice types. In the present study, we evaluated the strength of aroma in 45 F1 hybrids and their 10 parents grown in humid sub-tropical zone at the foothills of shivalik range of the Himalayas, popularly known as ‘Tarai’. Of the total 55 rice genotypes, 38 F1 hybrids and 10 varieties possessed strong aromatic strength, four F1 hybrids had moderate aromatic strength whereas three F1 hybrids possessed low aroma. The significance of aromatic strength was tested by DMRT and pair wise comparisons were made among all genotypes. Based on the performance, 55 rice genotypes were grouped into 11 clusters. These clusters and their occupied genotypes were significant at 5% level of significance. In this study most of the rice genotypes performed strong aromatic strength and therefore prospects exists for improvement of aromatic strength on rice.
