Abstract
A field experiment was conducted in sandy loam soil during two consecutive spring seasons, 2012 and 2013, to determine the behavioral effects of sowing dates on growth, yield attributes, and yield of popular varieties of blackgram. Results revealed that maximum grain yield was recorded when blackgram sown on 25th February. It was due to higher number of pods plant-1, number on grain pod-1, yield plant-1 and maximum 100 grain weight. However sowing had done on 25th February was statistically at par with crop sown on 10th March and they produced significantly higher grain yield (39% and 26%, respectively) than earlier sowing on 10th February, on the mean basis of two years grain yield. In varietal performance, cultivar Shekhar-2 yielded more grain yield than Shekhar-1, Azad-1, Azad-2, and Etawah local, respectively.

Abstract
Eight random primers were used for evaluating genetic diversity among eighteen OUAT released rice cultivars of Orissa and development of variety-specific diagnostic features. A total of 69 reproducible bands were amplified, of which 53 (76.8%) were found to be polymorphic, while 16 (23.2%) were monomorphic. The number of bands detected per locus ranged from 4 (OPG-18) to 12 (OPG-2, OPH-2) with an average of 8.5 bands per primer. The size of amplified product ranged from 300 bp (OPB-10, OPH-2) to 2500 bp (OPB-2). Average polymorphism in all the 18 cultivars using eight random primers was found to be 71.61%. Among all the primers in eighteen cultivars, OPG-2 has shown 100% polymorphism. Based on the primer resolving power and polymorphism information content (PIC), among all the primers OPG-2 has shown highest resolving power (4.11) and highest PIC (0.34). Six cultivars (Sarathi, Rajeswari, Mahalaxmi, Subhadra, Ghanteswari and Upahar) could be identified on the basis of presence of single unique markers and 7 cultivars (Ghangeswari, Subhadra, Rajeswari, Prachi, Sarathi, Upahar and Jajati) were identified due to the absence of single marker present in all other varieties. OPB-2 amplified unique bands of 450 bp and 750 bp in Sarathi and Rajeswari cultivars. OPB-10 amplified 625 bp of unique band in Mahalaxmi cultivar. OPC-7 has amplified 600 bp, 700 bp and 850 bp unique bands in Ghanteswari cultivar and 575 bp unique band in Subhadra cultivar. OPF-7 amplified 625 bp unique band in Upahar variety. OPH-2 amplified 350 bp and 1000 bp unique bands in Upahar and Sarathi cultivars, respectively. Similarity index of pair-wise comparisons estimated on the basis of all the 8 primers ranged from 0.652 to 0.956. Badami showed highest similarity with Nilagiri (0.956) while Upahar showed least similarity with Khandagiri (0.652). The average genetic similarity for the eighteen cultivars was found to be 0.817 and it ranges from 0.751 (Rajeswari) to 0.861 (Gouri). Cluster analysis based on Jaccard’s coefficient method indicated that all the eighteen OUAT released rice cultivars were classified into two major clusters I and II. RAPD analysis offered a rapid and reliable method for the estimation of variability between different accessions, which could be utilized by the breeders for further improvement of the rice cultivars.

Abstract
A study was conducted to examine the trends of annual mean temperature, annual mean maximum temperature and annual mean minimum temperature at IGKV Farm, Raipur. The trends of annual mean temperature and annual mean maximum temperature were negative whereas, the trend of annual mean minimum temperature was positive. In case of extreme values, 5 coldest mornings were more recent in nature (1986-2003) than the 5 hottest daytimes (1973-1998). An all time high temperature (47.6oC) was recorded on May 30, 1998 and an all time low temperature 3.6oC) was recorded on January 6, 1986. Frequencies of hot days were found decreasing, whereas, hot nights, cold days and cold nights were increasing with the progress of time. The number of ‘hot days’ was maximum (74) in 1975 and minimum (21) in 1971. The number of hot nights (17) was maximum in 2011 and was minimum (0) in 1974, 1990 1992, 1994 and 2010. Except the trend of annual mean minimum temperature, all other parameters looked like contradicting the popular global warming concept. Everyone is aware of global warming and hot extremities, but the cooler side is also increasing and we may have to think about protection of crops against cold extremities like cold injuries and frost in the near future.

Abstract
Most of the fungicides, plant extracts and their combinations tested under in vitro conditions were found effective against Botrytis cinerea, causal organism of grey mould of strawberry. All the eight fungicides evaluated were found effective and Derosal (carbendazim), Anokhi (mancozeb 12% + carbendazim 63%) and Malconda (hexaconazole) completely inhibited the mycelial growth of the pathogen both at recommended and half of the recommended doses. Amongst nine plant extracts, neem, datura and garlic extracts were found most effective at 10 and 15 per cent concentrations. Nine best possible combinations of fungicide and plant extract were also evaluated under in vitro conditions and it was observed that all the combinations inhibited the mycelial growth of the pathogen significantly over the control.

Abstract
The stable rainfall periods are helpful to analyzed for assessing the suitability of rainfed rice cultivation. It is defined as the period when weekly rainfall exceeds 50mm and corresponding CV is below 100 per cent. Based on the daily weather data the average weather conditions during different growth stages of rice crop of different stations are computed. It was found that the temperature during seedling, vegetative, reproductive stages is higher at Bilaspur and lower at Jagdalpur. The temperatures are not a limiting factor at any stages for rice crop in Chhattisgarh. Sun shine is the only limiting factor in Chhattisgarh for rice cultivation during seedling stage. The production potential of rice is very lowest at Jagdalpur and which is also lower in other stations during kharif season. Due to high relative humidity the water requirement of rice crop during kharif season in Chhattisgarh is lowest however higher relative humidity over are congenial to pest and diseases in Chhattisgarh.

Abstract
An attempt was made to evaluate backcross derived male sterile populations for important floral traits and judging the association among floral traits under study. Results revealed that between two populations,IR70369A × MAS99 cross derived population has higher range and mean values for floral traits especially higher stigma exertion which is highly associated with outcrossing. In addition correlation studies inferred that, style length was positively correlated with stigma exertion in both IR70369A × MAS99 (0.40) and KCMS31A × MAS99 (0.31) derived populations. Stigma length was also found positively correlated with stigma exertion in both IR70369A × MAS99 (0.35) and KCMS31A × MAS99 (0.60) derived populations however there was no significant association observed between style length and stigma length. This indicates that higher the style length and stigma length higher will be the stigma exertion. The study infers that between two populations studied IR70369A × MAS99 derived one has plants with superior floral traits and also the study confirms that the stigma exertion has positive association with style length and stigma length.

Abstract
The fresh water spring ecosystems situated at foot hills of Pir Panchal range of Kashmir Himalayas have a tremendous potential for trout fish culture besides providing drinking water to the rising populations and irrigating the fields. However valley is losing many of these fresh water resources due to contamination through natural as well as human interferences. The nutrient enrichment in these biotopes results in greater algal growth, increased turbidity, physico-chemical and biological changes that are detrimental to native species besides human health. The present study has been undertaken to investigate population dynamics of benthic macroinvertebrate community and its use for assessing and monitoring the limnochemistry of some fresh water spring ecosystems of Kashmir Himalayas. The physical heterogeneity of the substrate, spring discharge, spring size and flow variability are the primary determinants of the macroinvertebrate community structure. Species abundance also varied with seasonal conditions being higher in summer season and decreased during the winter season. The relatively higher density of annelids is associated with thick muddy substrate enriched with organic matter mainly due to intense anthropogenic activities associated with the spring. The presence of May flies and caddis flies (pollution sensitive) indicates well aerated waters with little anthropogenic pressure while as presence of chironomid larvae revealed polluted water body as these can thrive well in oxygen deficient environment.

Abstract
An investigation was carried out to know the influence of chemicals on flowering and fruiting characteristics of ‘Kesar’ mango at Horticulture farm, College of Agriculture (NAU), Bharuch during the year 2013-2014. Thirteen treatments comprised of KNO3 with 0.5%, 1.0% and 1.5%, Cycocel with 50 ppm, 100 ppm and 150 ppm, Ethrel with 100 ppm, 200 ppm and 300 ppm and KH2PO4 with 0.5%, 1.0% and 1.5% including control were used in randomized block design with three replications. The foliar application of chemicals applied twice during the investigation, once at flower bud differentiation followed by another spray during the full bloom stage in eight year old ‘Kesar’ mango orchard. Flowering and fruiting characteristics were significantly influenced by various chemicals treatment during the investigation as compare to control. The foliar application of KNO3 1.0% (T3 treatment) noted maximum flowering percentage (26.12%), fruit set percentage (0.21%) and Fruit retention percentage (20.45%) statistically at par with KH2PO4 0.5% and Ethrel 200 ppm. However, the highest number of fruit per panicle (2.10), number of fruit per tree (276.33) and fruit yield (11.30 ton/ha) recorded by KNO3 1.0% (T3 treatment) was closely followed by treatment T11 (KH2PO4 0.5%) and T9 (Ethrel 200 ppm) in ‘Kesar’ mango.

Abstract
Correlation and path analysis were carried out with sixty one genotypes of ragi for different yield and its component characters. Character association analysis revealed the significant and positive association of plant height, number of tillers/plant, number of productive tillers/plant, number of fingers/earhead and ear weight/plant with grain yield/plant in ragi. Path coefficient analysis revealed that ear weight/plant exerted the highest positive direct effect on grain yield/plant. It was also revealed that number of fingers/earhead, number of productive tillers/plant, and plant height contributed indirectly to grain yield/plant through ear weight/plant. These characters also exhibited highly significant positive association with grain yield as well as among themselves. Hence, simultaneous selection for ear weight/plant, plant height, number of productive tillers/plant and number of fingers/earhead will be more rewarding for obtaining the high yielding genotypes in ragi.

Abstract
A Field experiment was conducted during the Kharif season of 2012 and 2013 at Bihar Agricultural University, Sabour, (Bihar) to evaluate the effect of different nitrogen levels and varieties on yield, growth and nutrient uptake of scented rice (Oryza sativa L). The experiment was conducted in split plot design with 3 replications with treatments comprising three recommended dose of nitrogen (RDN) levels viz 50% RDN (40:40:20 kg/ha), 100% RDN (80:40:20 kg/ha) and 150% RDN (120:40:20 kg/ha) in main plots and five different rice varieties viz RAU 3036, RAU 3055, Rajendra Suwasani, Rajendra Kasturi and Rajendra Bhagwati in sub-plots. The results revealed that maximum effective panicles/m2, No. of grains per panicle, leaf area index, chlorophyll content, test weight, panicle length (cm) and grain yield (q/ha) were the highest value at 150% RDN. The highest grain yield was obtained with 150% RDN (35.29 q/ha) which was at par with 100% of RDN (34.22 q/ha) but significantly superior over 50% RDN (30.93 q/ha). Amongst the varieties Rajendra Bhagwati was found to be the best and gave significantly more grain yield (44.56 q/ha) than other varieties. The varieties RAU 3055 (39.33 q/ha), RAU 3036 (37.93 q/ha) and Rajendra Kasturi (37.53 q/ha) were significantly at par with each other. Total uptake of NPK was recorded maximum with Rajendra Bhagwati and 150% RDN (94.29, 23.75, 96.65 and 74.10, 18.76, 76.56 kg/ha respectively). The treatments 150% RDN and 100% RDN gave the highest net return (₹ 24181 and ₹ 23683/ha) and B:C ratio (1.95 and 1.97 respectively). Amongst varieties, maximum net return and B:C ratio (₹ 39384/ha and 2.71 respectively) was recorded with variety Rajendra Bhagwati.

Abstract
The present study was carried out with 26 derived lines for shoot fly resistance and three checks, to estimate the various variability parameters and heritablity. Two sets of planting were done; first planting was done to record observations on yield and yield contributing traits. Second planting was done for screening of shoot fly reaction under artificial epiphytic conditions; late planting technique and infector row technique were used for creating sufficient shoot fly pressure. The analysis of variance revealed that significant difference among genotypes for all the traits, suggesting presence of wide range of variation among the genotypes for all the characters under study. Mean values for the lines AKENT - 101, AKENT - 104, AKENT - 107, AKENT - 117, AKENT - 123, AKENT – 125 and IS 18551, showed shoot fly reaction, these lines exhibiting comparatively low number of eggs per plant, minimum dead heart count, low chlorophyll content index and high trichome density per mm2. High heritability (broad sense) was recorded for trichome density per mm2 due to high additive gene action.

Abstract
A study was conducted to standardize the screen size for grading of sweet corn cultivars viz Priya and Madhuri. Freshly harvested seeds were subjected to grading using hand screen of different sizes 3.50, 4.50, 5.00 and 5.25 mm (slotted) and evaluated for the seed quality parameters. The results showed that seed recovery per cent was highest in 3.50 mm (86.43%) screen size and lowest in 5.25 mm (70.00%). The seed quality parameters viz seed density (0.7652 g/cc), 100 seed weight (19.71 g), germination (89.02%), seedling length (30.50 cm) and vigour index (2682) were maximum in 5.25 mm screen size. While, lowest was noticed in 3.50 mm (0.7328 g/cc, 11.90 g, 83.38%, 21.90 cm and 1845 respectively). With an increase in sieve size the seed quality parameters increased in both the cultivars at marginal expense of seed recovery. The present findings revealed that there is a need to revise the screen size to grade sweet corn cultivars to minimize the processing loss.

Abstract
The present investigation was conducted during the year 2011-2013 with the objectives of studying the influence of INM practices comprised of organic inorganic and biofertilizer on availability of soil nutrients in African marigold cv. Sirakole in three seasons. The experiment was laid out in randomized block design which consisted of 15 treatments, each replicated thrice during kharif, rabi and summer season. The results of the study revealed that various nutrient management practices had significant influence on nutrient availability in soil after the harvesting of the crop in all three seasons. Nitrogen, phosphorus and potassium availability was highest in the plants supplied with 50% organic and 50% inorganic fertilizer along with biofertilizers in rabi season. Pooled over the seasons indicated that plants receiving nutrient combination of poultry manure (25% RDN) + vermicompost (25% RDN) + 50% RD ‛NPʼ + biofertilizers exhibited highest nutrient availability in rabi season.

Abstract
The present investigation was undertaken to estimate the genetic parameters on 11 quantitative and 6 nutritional traits with 61 ragi genotypes. Analysis of variance revealed significant differences among the genotypes for all the characters studied, indicating the presence of considerable amount of variability in the materials. The genotypes IE-5367, IE-5763, IE-6421, VL- 352, BBM-11, TNAU-1060 and GPU-83 recorded high mean performance for grain yield and number of tillers/plant, number of productive tillers/plant, number of fingers/earhead, earhead length, finger length and ear weight/plant. Hence, these genotypes can be utilized in the hybridization programmes to bring grain yield improvement in ragi. The estimates of GCV, PCV, heritability (broad sense) and genetic advance as percent of mean were recorded high for days to 50% flowering, days to maturity, earhead length, finger length, ear weight/plant, iron content, zinc content, copper content, manganese content, calcium content, protein content and grain yield/plant indicating that simple selection would be helpful for the improvement of these traits as these are governed by additive gene action whereas number of tillers/plant and number of productive tillers/plant recoded moderate heritability and genetic advance suggesting that characters are governed by both additive and non additive gene action.

Abstract
A study was conducted to know the extent of variability for yield and yield components in different genotypes of spine gourd collected from different regions of Madhya Pradesh. Ninety genotypes of spine gourd collected from different regions of Madhya Pradesh were tested in randomized block design replicated twice during the year 2013-14. Analysis of variance revealed the presence of considerable amount of genetic variability for yield and its component traits under study. Germplasm MSG-17 produced the highest fruit yield followed by MSG-39 and MSG-79. Fruits were produced for longer period in MSG-23 followed by MSG-17 and MSG-22. Genotypes MSG-59 followed by MSG-23 and MSG-42 were found to be early as they required lesser number of days to first fruit harvest. On the basis of mean performance for growth, earliness, fruit attributes and quality traits, the genotypes MSG-17, MSG-39 and MSG-79 were found not only high yielding but also with acceptable fruit quality. Highest phenotypic and genotypic coefficients of variation were recorded for the characters viz number of shoot per plant, number of fruit per plant and fruit yield per plant. Heritability estimates (broad sense) for different characters were ranged from very high degree to low i e from 99.94 to 6.65 percent.

Abstract
Chickpea productivity is limited by various environmental factors and temperature is one of the most important determinants of crop yield. High temperature is considered as a serious threat to crop production worldwide. Chickpea is a winter season crop and thus its terminal part of life is exposed to high temperature stress. Photosynthesis is one of the most heat sensitive physiological processes in C3 plant like chickpea. Bioregulators have been recognized for their role in protection of photosynthetic machinery. Therefore, in order to analyze the potential foliar application of some bioregulators (viz abscisic acid (ABA), benzyladenine, (BA) and salicylic acid (SA)) for improving photosynthesis, and other physiological parameters under high temperature condition, present investigation was undertaken using kabuli type chickpea variety (Pusa-1108) and high temperature stress was imposed by delaying the sowing dates (i e normal sowing and late sowing) to expose the terminal phase of crop to high temperature. Observations were recorded on pollen viability, stem anatomy and seed yield. Under high temperature stress interestingly, application of bio-regulators (ABA, BA, SA) in general, maintained the higher value of pollen viability and higher development of secondary phloem. Present findings indicated that the foliar application of ABA, BA and SA have higher pollen viability and made the plant photosynthetically more efficient under late sown high temperature condition.

Abstract
Eighty safflower genotypes representing diverse geographic regions were studied for genetic divergence using Mahalanobis D2 static. The genotypes were grouped into 16 clusters. Biological yield contributed maximum to the total divergence followed by plant height. Germplasms of Cluster V may be crossed with germplasm of cluster XVI, XIII, XI to obtain high heterotic response and desirable segregants. Cluster V having 7 germplasms may form good combination for hybridization with germplasm accessions of solitary cluster viz PI543995 (cluster II), PI514630 (cluster VI), PI273876 (cluster VII), PI237549 (cluster VIII), PI209287 (cluster IX), NARI-6-2 (cluster XI), A-2 (cluster XII), PI386174 (cluster XIII), PI405984 (cluster XIV), PI406015 (cluster XV), NARI-6(XVI). The maximum inter cluster distance was observed between cluster V and cluster XVI whereas minimum distance between the clusters IV and XII. The germplasm of clusters which secured overall high resulting high ranking across 11 characters viz PI514630 (cluster VI) PI406015 (cluster XV), NARI-6 (XVI), PI237549 (cluster VIII), PI405984 (cluster XIV) are considered most promising germplasm accessions and can be extensively used for the breeding programme to generate new material. Selection of the genotypes from these clusters for hybridization programme may result in good recombinants.

Abstract
Quality of rice is an important criterion for the choice and demand by rice consumers and it is determined by physicochemical parameters. The objective of this research was to screen physical, milling, cooking and nutritional properties of high yielding rice varieties being cultivated in India. All the studied varieties can be judged as slender except Jaya and KCP-1 (classified as bold). The highest milling yield and head rice recovery was recorded in cvs. KRH-4 (74.00% and 68.50%) and MTU-1001 (72.00% and 65.60%), respectively. Significantly cv. Thanu took least time for cooking (19 min) compared to other varieties, whereas grain elongation was highest in KMP-175 (1.19 mm). Majority of the rice varieties were of intermediate gelatinization temperatures, while 11 out of 37 varieties had low gelatinization temperature. Protein content was ranged from 10.12 to 14.63% with the mean of 12.84%. Five varieties were recorded <12.00% and 32 were found to possess >12.00% protein. The Amylose content of the tested entries ranged from 9.21 to 14.0%. Most of the studied varieties possess >12.00% Amylose content and it was found to be highest in cv. KRH-4 (14.00%) and lowest in Gangavathi Sona (9.12%) and Mugaud Suganda (9.21%). The zinc content was more than 20 ppm in 33 varieties and highest was found in KRH-4 (27.61 ppm) and lowest in Mangala (17.11 ppm).

Abstract
Onion is an important commercial vegetable cum spice crop cultivated extensively and is mainly used for its flavour and pungency. In Odisha the productivity of onion is around 60.45 tonnes ha-1 which is comparatively very low. The low productivity of onion is mainly associated with poor nutrient management and more particularly nitrogen whose deficiency limits synthesis of chlorophyll, enzymes and proteins. However, the area under onion cultivation is increasing day by day and hence improved management practices are necessary to give a good yield with qualitative, quantitative and marketable parameters. Therefore, the present investigation was carried out with the sole objective of studying the effect of biofertilizers, inorganic fertilizer levels and organic amendments on the growth and yield of onion and to recommend the most appropriate combinations, which could be considered for the commercial cultivation of onion under Bhubaneswar agro-climatic condition. Application of recommended doses of inorganic fertilizers in different levels along with biofertilizers and organic amendments increased the yield of bulbs significantly over all other treatment combinations. Maximum yield (9.31 tonnes ha-1) of bulbs recorded in treatments receiving 75% of recommended dose of inorganic fertilizers along with biofertilizers and organic amendments which was nearly 80% more than the treatment receiving recommended dose of fertilizers (RDF) only. The highest yield under the former treatment may be attributed to the sum of yield attributing characters viz plant height, number of leaves per plant, bulb diameter, number of rings per bulb, root count etc. Yield per unit area also increased significantly over control by the application of inorganic fertilizers or biofertilizers alone but the combined effect of chemical fertilizers along with the biofertilizers and organic amendments yielded the highest as the biofertilizers boosted the yield attributing characters. Integration of biofertilizers with inorganic fertilizers help reduce the use of recommended dose of inorganic fertilizers by 25% while maintaining the desired yield level. Results further showed that microbial biomass carbon (MBC) and microbial biomass respiration (MBR) were significantly influenced by the balanced and integrated application of biofertilizers with chemical fertilizers and organic amendments.

Abstract
Maize (Zea mays L.) is a versatile crop grown over a range of agro climatic zones. It is a crop par excellence for food, feed and industrial utilization. Inbred lines as parental components for hybridization are the most valuable source in maize genetics and breeding. DUS Testing as one of the important criteria to test the inbred lines for distinctness, uniformity and stability studies were initiated to evaluate and characterize the inbred lines for morpho- economic traits for selection of inbreds for breeding programme. The results of the study revealed that the qualitative and quantitative characters expressed a considerable amount of variation. The anthocyanin pigmentation in silk was observed to be present in 10 inbreds while it was absent in 27 inbreds. The days to 50% tasseling ranged between 49 days to 70 days where the inbreds VIM 244 had early flowering and VIM 249 with late flowering. Hierarchial clustering of the present study resulted in grouping of inbreds into 6 major clusters with the maximum number of inbreds clustered in I and V. Based on the mean cluster distance, it was observed that cluster I and V are highly dissimilar. The genotypes VIM 216 and VIM 228 had maximum similarity with an index of 8.90. Dendrograms were constructed based on the morpho-economic characters that established differences among the individuals indicating reportable variation which would aid in selection of inbreds with desirable characters for further breeding programme.

Abstract
A field experiment was conducted at Agronomy Farm, College of Agriculture, Nagpur during rabi season 2013-2014 on linseed, to study the effect of land configuration and nutrient management on productivity of irrigated linseed with split plot design. The treatment consisted of three levels of land configuration viz Flat bed (L1), opening of furrow in every row (L2) and opening of furrow after two rows (L3) and four of nutrient management, 75% RDF + Azotobacter + PSB (N1), 100% RDF (N2), 100% RDF + Azotobacter + PSB (N3) and 125% RDF (N4). Application of land configuration treatment opening of furrow in every row significantly increases plant height, number of branches, dry matter accumulation as well as yield contributing character such as number of capsule plant-1, number of seed capsule-1, test weight, seed yield plant-1, seed yield and straw yield ha-1. In case of nutrient management application of treatment 125% RDF followed by 100% RDF + Azotobacter + PSB increased all growth and yield attributing characters over treatment 75% RDF + Azotobacter + PSB. Interaction effect of land configuration and nutrient management were found to be significant in case of yield parameters like seed yield g plant-1, seed yield q ha-1 and straw yield q ha-1. The treatment opening of furrow in every row with 125% RDF (L2N4) recorded more seed yield g plant-1, seed yield q ha-1 and straw yield q ha-1 among all other interaction combinations.

Abstract
Fossil fuels are coming to the end, up to 2040, all the resources of fossil fuels will be finished (Biofuels 2020). So for this reason all are focusing their view on the alternative renewable energy resource biodiesel. In favour of that the target should be of raising of biofuel tree species. The seedlings will start seeding at the age of 8-10 years but by the use of this grafted seedling one can get seeds at the 4-5 years only. The present study was done to find out the best month with great percent success of grafting in biofuel tree species. In this regard, three biofuel species viz Pongamia, Neem and Simarouba. Under Pongamia RAK-106, RAK-89, MTP-II and MTP-III varieties were selected among neem varieties viz Gulbarga, Dharwad, Raichur and Bijapur were selected and for Simarouba Kali variety was selected for wedge grafting which was done on first fortnight of every month. About 86-95% success in grafting was achieved through wedge grafting in all the biofuel species tested.

Abstract
An experiment was conducted to evaluate the effect of gibberellic acid and propagation media on relative growth rate, absolute growth rate and leaf chlorophyll content (A, B and total) in papaya seedlings. The study revealed that, seed priming with GA3 200 significantly influenced relative growth rate and leaf chlorophyll content. Among propagation media, media composed of either vermicompost or farmyard manure (FYM) greatly enhanced growth rates and leaf chlorophyll content. Interaction of seed priming with GA3 200 ppm and soil, sand, cocopeat and vermicompost (1:1:1:1) media significantly increased absolute growth rate, relative growth rate and leaf chlorophyll content of papaya seedling.

Abstract
PGPR enhance the plant growth and soil fertility by direct and indirect means. Direct means through nutrient supply such as biological nitrogen fixation, phosphate solubilization, production of plant growth promoting substances like IAA etc. Indirect means through biocontrol activity by production of siderophores and HCN. Plant growth promoting rhizobacteria (PGPR) are a group of bacteria that can be found in the rhizosphere. In the present study, eight rhizospheric soil samples were collected from Student Farm, College Farm Rajendranagar Hyderabad (India). Isolates were further identified on the basis of colony morphology, Gram staining and biochemical tests. These isolates were identified as Rhizobium. A total of 15 Rhizobial isolates were isolated and in vitro screening was done for different plant growth promotion activities i e phosphate solublization, IAA production, ammonia production, HCN production and Antagonistic activity etc. In the present work the bacterial isolates were shown good results in Phosphate solubilisation, Ammonia production, IAA production and HCN production and also in a biochemical tests. Therefore, Selection of these bacterial isolates can be utilized for abiotic stresses would benefit the end-user by successful establishment of the strain for showing desired effects. Microorganisms help agricultural plants to increase their tolerance and adaptation to abiotic stresses. Identification of microbial candidate strains with stress tolerance and other added characteristic features would help the end-user obtain the desired beneficial effects.

Abstract
The objective of this study was to explore the effect of genotype (G) and genotype × environment interaction (GEI) on yield of 10 promising varieties of rice in 30 different environments. Yield data were analyzed using the GGE bi-plot method. Significant E, G and G × E interaction explained 2.51%, 13.86% and 10.76% of the total sum of squares respectively. The first 2 principal components (PC1 and PC2) were used to create a 2-dimensional GGE biplot and explained 68.0% and 9.9% of GGE sum of squares (SS), respectively. Collective analysis of the biplots suggested five rice varieties of mega-environments in Chhattisgarh. The highest stability was attributed to genotypes G1 (Swarna) was the best performer in all environments, followed by G2 (MTU-1010), G3 (MTU-1001), G5 (IR-64) and G4 (IR-64). Genotypes G1 (Swarna) and G2 (MTU-1010) had the highest yield stability. Suitable environments are E13 (Durg), E18 (Rajnandgaon) and E15 (Durg).

Abstract
Seed mycoflora resident on seed served as primary inoculum and affecting seed rot, seed germination, seedling blight and the later stages some diseases appeared in the standing field crop. Consequently yield is reduced occurring significantly monetary loss. Standard blotter test and agar plate test were used to isolate the seed mycoflora associated with the seeds (sterilized and unsterilized). Total ten different fungi viz Aspergillus niger, Aspergillus flavus, Fusarium semitectum, Fusarium oxysporium, F. moniliforme, Alternaria alternata, Rhizoctonia bataticola, Botryodiplodia theobromae, Rhizopus nigricans and Mucor sp. were recovered from unsterilized and sterilized seeds. Among the seed mycoflora, Aspergillus niger, R. bataticola and Aspergillus flavus were found to be dominant while Fusarum oxysporum, F. moniliforme, Botryodiplodia theobromae and Mucor spp were sub-dominant and F. semitectum, Alternaria alternata and Rhizopus nigricans less frequent. In the present studies, out of ten cultivars tested three cultivars namely TAG-24, TAG-37A and JL-24 were found highly susceptible whereas seven cultivars namely PM-1, PM-2, UG-92, UG-94, UG-100, UG-112 and UG-114 were found susceptible against R. bataticola in field conditions. Thus, among them none of the cultivars were found moderate to highly resistance. The pathogen was also screened against various family hosts and observed that all the plants showed disease infection except brinjal, bajra and sorghum. Maximum average plant mortality (46.66 per cent) was recorded in groundnut seedlings followed by soybean (32.50%) and minimum was in maize (6.66%) at 70 days after sowing.

Abstract
The present study aimed at assessment of variability and correlation for yield and yield contributing characters in 30 nutmeg genotypes was undertaken at Department of Horticulture, College of Agriculture, Dapoli Maharashtra. In present investigation the genotype exhibited wide range of variation for all the characters under study in nutmeg. The ANOVA revealed that the difference among the genotypes were highly significant for all the characters under study. This indicates that there is substantial scope for selection of the genotypes. Correlation coefficient is one of the important biometrical tools for formulating the selection index. Since, it reveals the strength of relationship among the group of character. Correlation studies were carried out to determine the degree of direction in between yield and yield contributing characters. In general most of the characters had higher genotypic correlation as compared to phenotypic correlation. The correlation analysis indicates that the most of the parameter except yield had strong and positive correlation among each other. Importantly yield had positive association with all these parameter and this association was significant.

Abstract
Boron (B) deficiency is becoming a common problem in South Asian countries especially in rice fields. Correcting B deficiency has potential to improve the rice productivity by foliar application of B is an easy and effective way. This experiment was conducted to evaluate the influence of foliar applied B (Control, 0.2, 0.4 and 0.8 ppm) on leaf, culm, panicle and total dry weights, yield and harvest index of rice cultivars (IET 20979, IET 21007, IET 21106, IET 21114, IET 21519, IET 21540 and Rasi (check)). B foliar application improved the culm, panicle dry weights whereas it decreases the leaf dry weight by translocation of more assimilates in to grains. TDM, yield and HI had a positive correlation with B concentration. However, foliar application of 0.4 ppm B was most effective in this regard. Difference between the cultivars for grain yield was observed. However, IET 21540 and IET 21519 were identified as good source potentials for culm and leaf respectively. Rasi check genotypes recorded maximum harvest index (HI) but was not a high yielder due to its low source potential. IET 20979, IET 21540 and IET 21106 had better source potentials in terms of TDM. Highest sink potential (maximum panicle weight) was recorded in genotypes IET 21519 and IET 21114. IET 20979 and IET 21106 were also had recorded more grain yield and HI. Improvement of grain yield with B application was attributed to increased translocation of assimilates.

Abstract
Rice is widely cultivated crop around the globe which includes more than 100 countries, with 700 plus million tones production annually and it is a major source of carbohydrate and staple food of more than 62% people in the world. Like all other crops, rice too suffers stress conditions caused by various biotic and abiotic factors. Among abiotic factors, the yield loss in rice due to cold or low temperature stress is about 45% at global level. In present study, based on response to cold shock treatment and score alloted, we had screened 52 different genotypes of rice, grown extensively across the Andhra Pradesh. Here we had used seedling colour, seedling height and germination percent after cold shock treatment as parameter for morphological assessment toward cold stress tolerance. Among those 52 genotypes 13 genotypes have shown higher ability to overcome the cold stress, and BR-11 is best among those 13 genotypes.

Abstract
Soil characteristics in relation to evaluation of fertility status of the soils of an area are an important aspect. Indian soils demands its build up and sustain at a high level to produce adequate food to feed its burgeoning population, proper management of soil fertility demands carefull fertilization of constraints of current nutrient deficiency and monitoring changes of soil fertility to predict areas to developing deficiencies. Ten representative villages were chosen and different numbers of surface soil samples (0-15cm) collected were analyzed for physico-chemical properties and available N,P,K,S and Zn status. Results revealed that soil samples were found low to medium in organic carbon, available nitrogen, available phosphorus, available potassium and available sulphur available zinc. About 87% of samples were found deficient in available zinc. Texture of soils varied from sandy clay loam to clay. Significant positive correlations were found to exist between organic carbon and available N, P, K, S, and Zn status of soil under study.

Abstract
A pot culture experiment was conducted on vertisols in the greenhouse of Department of Soil Science and Agricultural Chemistry, Rajendranagar, Hyderabad, to study the influence of crop cover and stage of crop growth on soil enzyme urease and acid and alkaline phosphatase activity in soil. The experiment was undertaken with three cereals – rice, sorghum and maize, two oil seeds – groundnut and sesame, two pulses – green gram and black gram, two vegetables – bhendi and brinjal. The experiment was conducted using crops as treatments in completely randomized block design with three replications along with the uncropped control. The enzyme activity increased from 0 days and reached peak level at 60 days for urease and 45 days for acid and alkaline phosphatases. The increase in urease activity (expressed as µg of NH4+ released g-1 soil h-1) ranged from 6.71 to 16.26 in groundnut, from 6.71 to 10.74 in black gram, from 6.70 to 10.45 in - green gram, from 6.69 to 10.28 in sesame, from 6.71 to 9.77 in rice, 6.70 to 8.97 in maize, from 6.69 to 8.84 in sorghum, from 6.68 to 7.72 in brinjal and from 6.69 to 7.83 in bhendi. The activity of urease, acid and alkaline phosphatase under different crop coverages followed the order groundnut >blackgram >greengram >sesame >rice >maize >sorghum >brinjal >bhendi. The presence and type of plants grown on a soil have shown a marked influence on enzyme activities, more over the levels of enzymes activity declined to nearly the original levels at harvest.

A field experiment was conducted at College of Horticulture, Bidar, Karnataka consequently for three years. The application of neem cake 2 t ha-1 + PSB + Azospirrillum @ 5 kg each ha-1resulted significantly higher leaf yield of palak. Even though some results are reported in 100% RDF which indicate that growth and yields are higher with chemical fertilizer but the quality of the green will reduce drastically. Growing of leafy vegetable under organic conditions not only improve the quality but also extends the self life. The increased uses of organic inputs are helpful not only for human health but also for plant and soil health.

Abstract
Twenty five (25) different lines of rice were evaluated to determine the genetic variability. Here we had recorded the significant variations for various characters under study. Our study has shown that the coefficient of variations for both genotypic as well as phenotypic, were highest for number of filled grains per panicle and lowest for days for 50% germination. The PCV and GCV for number of filled grains per panicle, number of panicle and number of spikelet shows that these characters can be used for selection.
