Abstract
Pleurotus mushroom, generally referred to as ‘Oyster mushroom or Dhingri’ in India is relatively new to the mushroom industry. In India, Odisha is a leading state in terms of oyster mushroom production. The condition in most of agro-climatic situation in Odisha are suitable for growing oyster mushroom from month of July to February comprising of the rainy and winter season. Pleurotus pulmonarius is a potential protein source especially in developing countries, besides having minerals and vitamins. Besides its edibility it has also got pharmaceutical properties. Hence, Pleurotus pulmonarius could well be incorporated in to the mushroom farming system during winter season besides the ruling species, as this species was not in cultivation earlier. Four different substrate pasteurization methods along with untreated done (control) were evaluated for their yield potential and superiority of steam treatment of substrate in terms of realization of mushroom yield (98.90%) was established in the investigation. However, yield obtained (96.63%) out of the treatment pasteurized with chemical was statistically at par with the steam treatment, through it was associated with longer incubation period (17.50 d) and crop duration (24.25 d). The untreated substrate (control) produced the lowest yield (79.28%). Nine organic supplements including control were evaluated for their influence on yield and yield attributing parameters of Pleurotus pulmonarius. The biological efficiency was reported numerically highest (93.37%) in boiled wheat which was at par with the yields realized from chicken manure (93.07%), boiled maize (92.53%), rice bran (92.33%), untreated control (91.07%), maize meal (91.10%) and bengal gram powder (90.99%). Among the six diverse bag dimensions, 30 × 25 cm bag accommodating 1500g substrate was superior in respect of biological efficiency.

Abstract
A field experiment was conducted during Rabi season 2013-14 and 2014-15 on sandy loam soil to study on Crop Research Centre Chirori of Sardar Vallabhbhai Patel University of Agriculture and Technology; Meerut (U.P.). The results revealed that application of 120% RDF of NPK were significantly higher plant height, number of spikelet’s spike-1, number of grains spike-1, test weight (g) than the other treatments during both the years. Application of 125% RDF recorded significantly highest grain yield 49.73 to 47.75 q ha-1 during 2013-14 and 2014-15, respectively. Among the various treatments where 125% NPK was applied proved to be superior and it statistically at par with T2 and T11 in terms of growth, yield attributes and yields during first and second years. Moreover the application of organic in integration with inorganic fertilizers could also maintain the soil fertility which is much important for sustainable crop production. The organic carbon and available NPK soil after harvest increase with the combined application of organic and inorganic with Biofertilizer. Integration of 75% NPK with VC @ 2.5 t ha-1 + PSB + Azotobacter was found better by improving the residual soil fertility status after the harvest of wheat crop.

Abstract
A field experiment was conducted during kharif season of 2016 to study the effect of organic nutrient management practices on growth and yield of Pigeon pea (Cajanus cajan (L.) Millsp.) in sandy loam soils of Zonal Agricultural and Horticultural Research Station, Navile, Shivamogga, Karnataka. Among the different nutrient management treatments, application of recommended dose of FYM (7.5 t ha-1) along with 100 percent N equivalent vermi-compost (2 t ha-1) has recorded significantly higher grain yield (10.89 q/ha) as compared to rest of the treatments. Similarly higher pods per plant (223.3 pods/plant) test weight (11.3 g/100 seeds) yield per plant (84 g/plant) also recorded with the same treatment and it was closely followed by the treatment which received recommended dose of FYM (7.5 t ha-1) along with application of 100 percent N equivalent FYM (5 t ha-1). Maximum soil microbial population at different growth stages were also observed in the treatment which received recommended dose of FYM along with 100 percent N equivalent vermi-compost. The same treatment recorded built up in available nutrient status as compared to initial levels. Hence, application of 2 ton vermi-compost along with 7.5 ton FYM is optimum for obtaining highest yield of pigeon pea under organic farming condition.

Abstract
Wheat is the second major food crop of the world in importance next to rice. The experiment was conducted at Research Farm, Indira Gandhi Krishivishwavidyalaya, Raipur during rabi 2013-14. Twenty two wheat genotypes including checks were grown in randomized block design with three replications. The objective of this study was to establish genetic variability in wheat. The present experiment was conducted and estimates of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV). The genotypic coefficient of variance (GCV) was found maximum for seed yield per plot (22.08) followed by number of seeds per plant (21.06), number of tillers per plant (15.80), biological yield per plot (14.74), plant height (14.19), spike length (14.03) whereas, genotypic coefficient of variation was lowest for days to maturity (5.09). Heritability in broad sense was calculated for each character. The characters days to 50% flowering (99.2), 1000-seed weight (96.6), days to maturity (96.2), plant height (82.1), number of seeds per plant (78.5), spike length (76.2) and seed yield per plot (73.3) exhibited high heritability whereas, biological yield per plot (66.1), number of seeds per spike (55.9) had moderate heritability. High heritability coupled with high genetic advance as percentage of mean was observed for seed yield per plot (38.92, 73.3), number of seeds per plant (38.43, 78.5), plant height (26.48, 82.1) and spike length (25.21, 76.2). Therefore, these characters should be given top priority during selection breeding in wheat.

Abstract
The primary objective of the paper is to study the spatial analysis of groundwater quality in Shahapur town and its surrounding area of Yadgir district, Karnataka State. Groundwater samples were collected from fifteen randomly selected bore wells in and around Shahapur town for a period of two seasons in the year 2013. The collected water samples were analyzed for physico-chemical characteristics like pH, EC, TDS, alkalinity, total hardness, sulphate, chloride and fluoride as per the standard methods. The concentrations of various parameters recorded in the following range; pH 6.96-7.75, EC 599-4510 µS/cm, TDS 274-2350 mg/L, alkalinity 192-1228 mg/L, total hardness 138-714 mg/L, chloride 66.66-2354.34 mg/L, sulphate 91.77-416.25 mg/L and fluoride 0.01-4.85 mg/L. The Geographic information system based groundwater quality mapping was prepared using ArcGIS software to know spatial variation in physico-chemical parameters of groundwater. The results shows that the quality of groundwater varies spatially for both pre and post monsoon season. Further, water quality index reveals that groundwater belongs to good, poor and very poor category. According to Bureau of Indian Standards, few water quality parameters exceeded the permissible level.

Abstract
The present study was carried out to examine the effect of seed deterioration on viability of Kalmegh seeds by subjected them to accelerated ageing at 45° C temperature and 100% relative humidity for 10 days. Various physiological parameters (moisture content, germination percentage, seedling vigor index I&II) and biochemical parameter (electrical conductivity) were explored. The results indicated that seed aging had significant effects on seed quality parameters of Kalmegh with an outcome of decreased speed and percentage of germination and decreased percentage of normal seedlings along with increased electrical conductivity and moisture content progressively with the increment in ageing period (7, 8, 9 and 10 DAA). Prolongation of ageing led to deterioration of both germinability and seed viability.

Abstract
Thirty three F1 rice hybrids along with complete set of 14 parents and checks were evaluated for variability, heritability and genetic advance in different yield and yield contributing traits. The data were recorded on five randomly selected plants for fifteen quantitative characters. The treatment, i.e. mean sum of squares due to genotypes showed significant differences for 14 characters studied, indicating the presence of high genetic variability among the genotypes. The estimates of GCV were lower than the respective PCV, indicating the influence of environmental factors on the expression of the traits studied. Biological yield per plant and grain yield per plant (98.65 and 98.58), followed by 1000 grain weight (98.48), pollen fertility % (98.36), number of fertile spikelet per panicle (96.62), number of sterile spikelets per panicle (96.08), and total spikelet per panicle (95.03) showed high heritability coupled with moderate genetic advance as percent of mean, suggesting that selection for the improvement of these characters may be rewarding. This also indicates greater role of non-additive gene action in their inheritance suggesting heterosis breeding could be used to improve these traits.

Abstract
Climate has emerged as one of the primary determinants of agriculture productivity. Since agriculture is the backbone of Indian economy, climate change poses serious threat to India’s food security and development. Adaptation strategies are responses to climate change that require deliberate policy decisions. Consequently, the scientists and policy makers are concerned about the adverse impact of climate change, and the need to develop the adaptation measures. The present study was undertaken to assess the adaptation of agricultural practices adopted by farmers to cope-up with climate change in Tehri Garhwal region of Uttarakhand state, India which is deemed to be vulnerable to climate change. Data for the study were collected from 110 farmers selected by using simple random sampling. The study findings indicated that majority of the respondents (92.73%) used adaptation practices to climate change. It was also found that change in crop varieties (71.81%), reduced number of livestock (70.90 %) and changes in sowing date (60.81%) were some of the adaptation measures followed by most of the farmers.

Abstract
Byadagi chilli is a famous chilli type grown in Karnataka, known for its deep red colour and zero pungency. Molecular characterization of Byadagi chilli (Capsicum annuumL.) was carried out using two different marker systems viz. RAPD and ISSR to identify specific markers linked to colour and pungency. Two KAU varieties viz. Ujwala and Anugraha were also included in the study for comparison with Byadagi chilli genotypes. The RAPD marker system could generate a total of 155 amplicons with fourteen primers and the ISSR marker system could generate a total of 103 amplicons with eleven primers. The dendrogram generated with RAPD and ISSR profiles grouped Byadagi cultivars and KAU varieties in separate clusters. Eight amplicons resolved with five primers (S12, S13, OPA06, OPA10 and OPE18) in RAPD marker system and twelve amplicons resolved with seven primers (2UBCS2, ISSR05, ISSR08, ISSR15, UBC823, UBC840 and 17899A) in ISSR marker system were found specific to Byadagi Kaddi and Byadagi Dabbi. Molecular characterization attempted in the study distinguishes the Byadagi cultivars from the KAU varieties with respect to colour and pungency. In depth investigations on the unique amplicons identified specific to Byadagi cultivars will give further insight into the genes involved in colour and pungency of chilli, which could be utilized further in marker assisted selection, metabolic pathway engineering and secondary metabolite production.

Abstract
A laboratory experiment was conducted during kharif, 2015 at Department of Crop Physiology, S. V. Agricultural College, Tirupati in completely randomized design with thirty maize genotypes. Maize genotypes were screened for seedling traits such as germination percentage, seedling vigour index (SVI), co-efficient of velocity of germination (CVG), root length and shoot length using Polyethylene Glycol- 6000. Two levels of osmotic stress (-5 and -10 bars) were created and performances were monitored against control. Genotypes were significantly varied for germination per cent, SVI and CVG. Results showed that the percentage of germination, SVI and CVG, root length and shoot length were decreased with increase in osmotic stress. At -10 bar, highest germination percentage was observed in PDM 1452, PDM 1485 which was at par with PDM 1409, PDM 1415, PDM 1428, PDM 1465, PDM 1479 and PDM 1468. Higher SVI at -10 bar was observed in PDM 1452 (609.00) which was at par with PDM 1488 (524.67), PDM 1474 (507.33) and PDM 1465 (502.60). Ten moisture stress tolerant genotypes (PDM 1409, PDM 1415, PDM 1428, PDM 1452, PDM 1465, PDM 1474, PDM 1479, PDM 1485, PDM 1488, PDM 1498) were selected from 30 maize genotypes through PEG experiment based on differences in seed germination and SVI. These ten genotypes were referred as tolerant having good germination percentage, SVI and CVG in control and moisture stress treatments (-5 bar and -10 bar).

Abstract
Brinjal (Solanum melongena L.) is one of the most popular and widely cultivated native vegetable crop of India. It is known as poor man’s vegetable and also called as eggplant. Many of the yield contributing characters is interacting in desirable and undesirable directions. Hence, the knowledge regarding the direct and indirect effect of various characters among themselves and with economic characters is necessary for making indirect selection for improvement of economic traits. Therefore the study has been taken up to analyze the path coefficient analysis in brinjal genotypes for seed content, fruit yield and its associated traits at College of Horticulture, UHS Campus, Bengaluru. Results obtained from path coefficient analysis studies computed among eighteen characters revealed that Number of fruits per plant had highest positive and direct effect on fruit yield per plant followed by pulp to seed ratio, fruit length, per cent fruit set, seed yield per fruit, plant height, average fruit weight, placental length, days to fifty per cent flowering and fruit diameter. Average fruit weight had highest positive and direct effect on fruit yield per plant followed by number of fruits per plant, fruit length, per cent fruit set, number of flowers per cluster, seed yield per fruit, pulp to seed ratio, plant height and days to fifty per cent flowering at both genotypic and phenotypic levels respectively.

Abstract
The investigation was conducted at College of Agriculture, Vellayani, Thiruvananthapuram during July to October 2016. Nine treatments viz. T1- spraying fermented cow dung water mixture (10%), T2- spraying citric acid (0.2%), T3- spraying sorghum water extract (5%), T4- spraying humic acid (1%), T5- spraying yeast extract (2%), T6- spraying moringa leaf extract (3%), T7- spraying salicylic acid (100 ppm), T8- spraying water and T9- no stress treatment were evaluated to assess their efficacy on inducing moisture stress tolerance and the effect on yield and irrigation requirement of container grown okra in urban homesteads. Among the organic preparations and biostimulants, spraying of sorghum water extract- 5 per cent recorded highest fruit weight (19.20 g fruit-1) while the fruit yield plant-1 was significantly higher (0.25 kg) on spraying citric acid or humic acid. Irrigation requirement was the lowest (19.04 L plant-1) and irrigation interval was highest (5.5 days) with spraying of citric acid while it produced water use efficiency which did not vary from no stress treatment. Spraying of citric acid was found to be the best treatment for inducing moisture stress tolerance and producing moderate yield expending less water.

Abstract
Experiments were conducted to find the various factors like evaporation, evapotranspiration (reference and crop) and deep percolation. By using the observed factor Kc value for the paddy was found. For this the technique used is the drum culture technique. Three drum culture techniques were conducted during the cropping period. Four drums of same size were selected out of which bottom of three drum were removed. A 2mm hole is made at the centre of the drum and covered with a rubber cork so that it can be closed and opened for entry and removal of water. A known volume of water is filled daily in all the drum and amount of water lost is observed both in the morning and afternoon. Amount of water lost from each drum gives the various components. Using that ET0 and ETc were reckoned. By dividing potential evapotranspiration (ETc) by reference evapotranspiration (ET0), Kc value can be determined. The average Kc value found from the three experiments conducted was 1.01, 1.16 and 0.9 receptively. Kc value found using the drum culture technique was similar with the FAO Kc value.

Abstract
A study was carried out to find out various buffalo management practices adopted by the farmers in Morena district of M.P. Approximately half of the farmers under survey 46.67 were able to provide insemination or natural service to their animals in heat at the right time, while 53.33% of farmers were unable to inseminate their animals in time due to various reasons. Only 8.33% farmers utilized the facility of artificial insemination, while 82.5% farmers opted for natural service. About 81.67% farmers fed green and dry roughage in combination and provided clean drinking water to their animals, but none of the farmer practiced silage making or other special treatments like chaffing, soaking or urea treating of wheat/paddy straw. Most of the farmers collected fodder from the fields. About 32.5% farmers fed additional concentrates to pregnant animals; the rest did not do this. As a part of summer management, only 12.50% farmers allowed their buffaloes to wallow in the village tanks while the 87.50% farmers practiced manual water splashing of buffalo during the hotter parts of the day. Washing of the animals and of their udders before milking were practiced by 10.28 and 98.40% farmers, respectively. Graded Murrah buffaloes were predominant in this region and the majority of the farmers were poor in certain aspects of scientific feeding, breeding, housing, milking and health care practices and needed to be educated.

Abstract
Chhattisgarh state (popularly known as Rice Bowl) is the most congenial for rice cultivation. Like other crops, rice crop is also known to suffer by many biotic and abiotic stresses and among biotic stresses, diseases are pivotal one. Correlation between sheath blight and weather variables was studied and it appears from the pooled correlation analysis between weather parameters and sheath blight disease severity that Tmax and SSH from 16 September to 30 October were found positively correlated in all three dates of sowing over four years kharif season under study. During this period of time, crop growth stage was in maximum tillering to panicle initiation stage coincide with the Tmax range (30.5-32.6oC) and SSH range (4.2-9.6) which favours the maximum sheath blight disease progression. During 16 September to 15 October in first and second dates of sowing, RHm suppose to influence the development of sheath blight disease. Year wise correlation analysis between weather variables and sheath blight disease severity suggest that Tmax and SSH had positive effect in the development of sheath blight disease of rice during kharif season.

Abstract
An investigation was carried out at Department of Microbiology, Kakatiya University, Warangal to study the distribution and characterization of plant growth promoting nitrogen fixing Azotobacter from three agroforestry tree species viz. Pongamia pinnata, Albizzia lebbeck and Acacia nilotica. The native population of Azotobacter in rhizosphere and non-rhizosphere varied from soil to soil and also with the tree species under investigation and a maximum Azotobacter population (67.41 × 105 CFU/g) was found in Kesamudram soils supporting the growth of P. pinnata. In a particular soil, in response to particular host root leachates, Azotobacters count was found to be on increasing side. The relative efficacy of PGP traits of P. pinnata isolates varied with the Azotobacter with maximum number of traits in AZETPP-1, AZKNPP-7, AZIDPP-9 and AZBLPP-13. Ammonia, GA, and IAA production were observed in 63.3 percent isolates. 70 percent of the isolates produced siderphores. Chitinase and β-1,3 glucanase production was recorded in very few isolates. Almost the same trend was observed in the isolates of A. lebbeck and A. nilotica. Azotobacter with an ability to produce more number of siderophores have exhibited a corresponding large zone on CAS agar. A temperature of 35°C was found to be suitable for most Azotobacter isolates. Azotobacter was able to tolerate 5.5-8.5 pH. Among all isolates, only five and three isolates have shown growth at 0.8 and 1 percent NaCl concentrations.

Abstract
The present study was carried out to investigate the allelopathic effect of two weeds Chenopodium murale L. and Coronopus didymus L. on germination and seedling growth of barley (Hordeum vulgare L.). Hot and cold aqueous shoot and root extracts of both weeds were applied at 50% and 100% concentrations to test seeds in Petri dish. The experiment was laid out in complete randomized design with three replicates. C. murale was found most effective on all the parameters (Germination percentage, GVI, SVI, shoot/root length and dry biomass) of barley seedlings. Cold root leachates of C. didymus were found to positively affect the root length and dry biomass of seedlings. Shoot leachates were more effective than root leachates while the hot water leachates were more effective than cold water leachates. Degree of inhibition increased with the increasing concentrations of applied doses.

Abstract
A field experiment was conducted at Regional Agriculture Testing and Demonstration Station Bilwa, Bareilly district of Uttar Pradesh to study the influence of fertilization on yield and quality on growth, yield and seed quality of mustard (Brassica juncea L.) cultivar Kranti. Fifteen treatments consisting of 100, 75 and 50 % of the recommended dose of fertilizers (RDF) either alone or with successive addition of farmyard manure (FYM 10 t/ha, sulphur @ 40 kg S/ha, zinc @ 25 kg ZnSO4/ha, boron@1 kg/B/ha) were tested. Application of 100% recommended dose of fertilizers along with farmyard manure resulted in maximum seed weight (22.7 g/plant), 1000-seed weight (4.6 g), seed yield (2348 Kg/ha), oil yield (915 kg/ha) and ash content ((5.10% on dry weight basis). The maximum oil content (41.15%) was recorded in treatment T15. The variations in growth and yield between 100, 75 and 50% recommended dose of fertilizers with farmyard manure, were significant. Significantly higher oil content was recorded at 50% recommended dose of fertilizers with farmyard manure, than over control. Hence, the farmer’s could economic benefit could be achieved with recommended doses of sulphur, zinc, boron along with farm yard manure.

Abstract
Ravages of lepidopteran pod borers during flowering and pod formation stage and pod fly during pod formation stage are the major bottlenecks in attainment of desired productivity levels of pigeonpea. Present study was framed to device cost effective and farmer friendly module for the management of pod borer complex in pigeonpea. Evaluation of eleven modules along with a control revealed superiority of the module 4 (spinosad 3.0 ml/ 10 L at 50% flowering stage - flubendiamide 480 SC 2.0 ml/ 10 L at 10 days after 1st spray - chlorantraniliprole 20 SC 3.0 ml/ 10 L at 20 days after 2nd spray), followed by module 8 (azadirachtin 10000 ppm 10 ml/ 10 L at 50% flowering stage -flubendiamide 480 SC 2.0 ml/ 10 L at 10 days after 1st spray- chlorantraniliprole 20 SC 3.0 ml/ 10 L at 20 days after 2nd spray), which registered lowest pod damage due to pod borer complex with highest monetary returns of ₹ 33399 and 27573 per ha respectively. However, the highest incremental cost benefit ratio of 1: 5.7 was obtained with module 8, followed by module 4 (1:5.1).

Abstract
The fascinating colorful dyes have increased the degree of pollution and exert serious problems in plant and animal life. The present work was centered to study the microbial decolorization of commonly used but recalcitrant textile dye Yellow 5G and textile effluent. Out of 68 bacterial isolates obtained, TS-1 and ES-27 was selected based on their efficiency to decolorize Yellow 5G and BTM effluent respectively, and exploited for further study. Initial decolorization of Yellow 5G and BTM by TS-1 and ES-27 was 50.9 and 46.9% respectively, whereas, on optimization of different culture conditions, percent decolorization was significantly increased up to 72.4 and 60.0%, but the combined action of TS-1 and ES-27 was even more efficient than the individual bacterial isolates. In account of optimized culture conditions, most preferred carbon and nitrogen sources were sucrose and ammonium chloride respectively. Decolorization was highest at pH 7.0 and temperature 35ºC with an inoculum size of 1.0%. Toxicity study also suggested that bacteria are able to decolorize the high concentration of dye and effluent. Moreover, immobilization potentially influenced the dye and effluent decolorization. Thus, both the bacterial isolates individually as well as in combination can be the potential candidates for cleaning up dye containing effluent.

Abstract
A field experiment was conducted S. V. Agricultural College, Tirupati to assess the impact of graded nutrient levels on three aerobic rice based cropping systems, comprising sunhemp during the summer, aerobic rice during kharif and three different crops in rabi, in terms of their nitrogen, phosphorus and potassium status of soil. Inclusion of legumes in the cropping system and higher level of graded nutrient levels improved the nitrogen, phosphorus and potassium status of soil. The crop sequences sunhemp-rice-groundnut and sunhemp-rice-maize showed a positive nutrient balance of soil and sunhemp-rice-sunflower reduced the nutrient status of soil, the maximum observed sunhemp-rice-groundnut. Inclusion of sunhemp and groundnut in sequence after aerobic rice increased the post harvest status of soil.

Abstract
Rice (Oryza sativa L.) is such a wonder crop that it can be grown under diversified edaphic condition like aerobic to anaerobic (amphibian in nature). In the present era of energy crisis and dearth of water, we cannot proceed with transplanted rice (TPR) on long path. Alternate to transplanted rice with water saving technology such as direct seeded rice, System of Rice Intensification. For this experiments were laid out in a randomized complete block design with three replications in four environments created agronomically, termed production systems of rice. They are conventional transplanted rice (TPR) and non-conventional viz. system of rice intensification (SRI), direct seeded dry (DSR, dry) and direct seeded wet (DSR, wet). Genotype Basmati 370 produced maximum plant height in all production system. Pusa Basmati-1121 has highest no. of effective tiller in all production system. Genotype Improved Pusa Basmati-1 had longest (28.47 cm) panicle in TPR and DSR (wet) (26.87 cm), Haryana Basmati-1 (28.94 cm) in SRI and Basmati-370 (27.51 cm) in DSR (dry). Pusa Sugandh-2 had heaviest (3.37g) panicle in TPR, SRI (3.55gm), and DSR (wet) (2.20 g) while Pusa RH-10 (2.10 g) in DSR (dry). PusaSugandh-3 had the maximum (21.23 g) grain yield in TPR, Pusa Basmati-6 (28.41 g) in SRI followed by Pusa Basmati-1121 (27.16 g), HKR 08-417 (22.42 g) in DSR (wet) and Pusa RH-10 (17.44 g) in DSR (dry). CSR-30 recorded the minimum grain yield in all production systems except SRI. SRI was the best production system in which eighteen genotypes performed better than TPR conventional.

Abstract
The experiment was conducted at Floriculture and Landscaping Block, College of Horticulture, VCSG, Uttarakhand University of Horticulture and Forestry, Bharsar during March- September month of the year 2016. The experiment consists of eight treatments which replicated thrice in a randomized complete bock design. The treatment consists of PSB @ 2 ml/L, Azotobacter @ 25 g/l, VAM @ 20 g/l and their combinations along with control. In all the treatments RDF (120:150:150 kg/ha) was applied as a common basal dose. The results of the study revealed that maximum number of sprouts per corm (2.20), plant height (73.40 cm) and number of leaves per plant (18.00) were recorded from the corms inoculated with PSB @ 2ml/l + Azotobacter @ 25 g/l + VAM @ 20 g/l + RDF. Similarly, minimum days taken to spike emergence (99.06) and maximum spike length (90.87 cm), number of florets per spike (16.33) length of floret (9.30 cm) and vase life (10.63 days) were also recorded in the same treatment. The results revealed application of biofertilizers had a non significant effect on number of days taken to full bloom of florets. Thus, it can be concluded that application of PSB @ 2ml/l + Azotobacter @ 25 g/l + VAM @ 20 g/l + RDF can be recommended for the commercial cultivation of gladiolus var. Arka Amar.

Abstract
Seven pedons were selected based on the variation in the soil site characteristics and studied for production potential and land use planning of Kumachahalli micro-watershed of Chamarajanagar district. The data were interpreted using qualitative methods of land evaluation. Qualitative methods included USDA land capability classification and FAO land suitability classification. The results obtained by land evaluation methods indicate the information on production potentials of soils. The study area was classified under land capability classes viz. II and III based on their susceptibility to erosion, soil depth, slope and climate limitation. The site characteristics of the mapping units of the study area (cultivable land) were matched with the soil-site suitability requirements for important crops. The FAO land suitability evaluation revealed the suitability for soils for sorghum, maize, groundnut, ragi, cotton, coconut and chilli. The mapping units on midlands were moderately to marginally suitable for majority of the crops because of limitations of drainage, climate and organic matter. In essence, of all the mapping units, some were not suitable for crops just because of the permanent limitation of soil depth. The results obtained in the present study will be helpful for preparing action plan of the study area.

Abstract
A study was conducted to evaluate the liquid formulations of Azospirillum sp. and PSB using amaranth as a test crop under field conditions. Based on the plant height, number of leaves, number of days taken for flowering and total biomass of the plant, the PSB (liquid formulation) was the most promising biofertilizer for enhancing the growth of amaranth. While comparing the performance of liquid and carrier based formulations of Azospirillum sp. and PSB, the liquid formulations of the two biofertilizers performed better than carrier based formulations. Results of the present studies indicated that liquid biofertilizers are better than carrier based formulations as the liquid formulations have better shelf-life and higher population of the bacterial isolate.

Abstract
The laboratory experiments were conducted to study on feeding orientation of C. cephalonica on treated wheat grains using choice method carried out during 2015-16 in the Department of Entomology, G. B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand. Relative attractancy of 30 days old larvae of C. cephalonica towards treated wheat grains after 24, 48 and 72 h of release. After 24 h of release of larvae of C. cephalonica, ash powder and Rynaxypyr (Coragen) treated wheat grains were found highly effective as no any larvae were found oriented towards the treated grains with negligible number of larvae attracted towards sand (0.67), chopped neem leaves and talcum powder (3.00 each) followed by ajwain seed powder (3.67), saw dust (4.33) followed by garlic capsules (5.00), salt (6.00), cow urine (7.33), cow dung cake powder (8.00) with highest attractancy of larvae was found towards untreated control (9.00). Similarly, after 72 h of release of C. cephalonica larvae on treated wheat grains, again ash powder and coragen showed no larval orientation towards them followed by sand (2.00), chopped neem leaves (2.33), ajwain seed powder (3.00), talcum powder (3.67), salt (5.67) and saw dust (4.33). Among the treatments, the maximum number of rice moth larvae oriented towards garlic capsules (5.33), cow dung cake powder (6.00), cow urine (7.33) and untreated control (10.33). After 48 h of release of C. cephalonica larvae for orientation among the treated wheat grains, movement of no larvae was observed again towards ash powder and Rynaxypyr (Coragen) treated wheat grains with the least number of rice moth larvae was attracted again towards sand (1.67) treated wheat grains followed by saw dust (2.67) and chopped neem leaves (2.67 each), talcum powder (3.67), cow dung cake powder (4.00), cow urine and salt (6.00 each), garlic capsules (6.67) with maximum number of larvae oriented towards untreated wheat grains (12.33).
