Abstract
Calcium in cationic form (Ca2+) plays a significant role in stress response of plants by connecting environmental stimuli to their suitable physiological responses. Calcium chloride applied as exogenous spray has been found to increase various plant growth parameters. In the present study three genotypes of common bean viz WB-185, WB-216 and Shalimar Rajmash-1 were used. Aqueous calcium chloride (HIMEDIA) solutions at 5, 10, and 20 mM containing 0.1% Tween 20 were sprayed on the leaves of bean. Control plants were sprayed with distilled water containing 0.1% Tween 20. Across the genotypes, all the traits except shoot dry weight had higher mean values at 10 mM calcium chloride concentration whereas for shoot dry weight higher value was recorded at 5 mM calcium chloride. The lowest values for all traits were recorded under water spray treatment. The analysis of variance for individual and interactive effects of genotypes and calcium chloride reveals that there was significant variation between genotypes for all traits whereas significant variation was revealed between treatment levels for all traits except shoot dry weight. The interactive effect of genotypes and calcium chloride were significant for rooting depth and root volume but non-significant for shoot dry weight and root dry weight. All the traits were significantly correlated except for root dry weight and rooting depth where correlation was positive but non-significant. The present investigation confirmed that pretreating plants under drought with CaCl2 can modulate the drought response across crops.

Abstract
Mycelium associated bacteria are known to play an important role in the morphogenesis and yield enhancement during oyster mushroom production. In an attempt to find the mycelium associated beneficial bacteria, one isolate each of Acinetobacter calcoaceticus (MGPB-1) and Rhizobium radiobacter (MGPB-2) found in association with the mycelia of Pleurotus florida and Hypsizygus ulmarius, respectively has been isolated. The 16S rRNA gene of each of the isolated bacteria was amplified using 1F (5’-GAGTTTGATCATGGCTCAG-3’) and 9R (5’-AAGGAGGTGATCCAACCGCA-3’) universal primers with a PCR Master mix reaction kit. DNA fragments of approximately 1,500 bp were purified using a QIA quick Gel Extraction Kit and were partially sequenced. The partial sequence data revealed the identity of bacterial strains (Gen-Bank Accession No. KT213564 and KT213565). When co-inoculated in dual culture plates, both the bacterial strains enhanced the mycelial growth and biomass production of P. forida and Hypsizygus ulmarius. It was further observed that the number and diversity of bacteria associated with P. florida and Hypsizygus ulmarius differed with the growth stages of the mushroom fungi in beds. More particularly, the population size and diversity increased during fruiting body induction.

Abstract
A Study was undertaken to evaluate the fertility status of Jaijaipur block in Janjgir- Champa district, Chhattisgarh covering 105 villages during 2011-2012. The systematic collection of samples in geo–referenced surface (0-0.15m) soils samples from 2485 sites representing Inceptisols, Alfisols and Vertisols using Global Positioning System. The samples were analyzed for pH, organic carbon and DTPA-extractable zinc. The statistical description of soil characteristics indicated that the pH of the soils varied from 4.3 to 8.1. The organic carbon content in these soils varied from 0.22 to 0.75% (mean-0.46%), which was observed to be low to medium in organic matter status. The DTPA-extractable Zn content ranged from 0.08 to 1.98 mg kg-1 with mean 0.68 mg kg-1 these results indicated that zinc is likely to be constraint for crop production in soils of Jaijaipur block. The correlation studies between available micronutrient Zn and soil properties (pH, OC) showed significant negative correlation.

Abstract
The field experiment consisted of three genotypes (Annigeri-1, JG-11 and JG-14) with five dates of sowing (from 40th to 48th standard week) laid out in a factorial randomized block design. Significant plant height, primary and secondary branches and total dry matter (29.21 g) were observed under D3 temperature regime with higher growing degree days (1637). This increasing total dry matter is due to higher leaf area which increases interception of solar radiation helps for the production of more photosynthates with higher partitioning and accumulation of dry matter in to different parts. This increasing dry matter accumulation and leaf area further increases other growth parameters like LAI, LAD, LAR, AGR, CGR, NAR (5.66, 0.381, 1.89, 24.15, 8.05 and 0.26 respectively) but RGR and SLW showing non significant differences among the genotypes and temperature regimes. The genotype JG-11 recorded more number of primary and secondary branches, leaf area, total dry matter and growing degree days including other growth parameter with a minimum plant height and optimum yield than the other genotypes.

Abstract
A field study was conducted with soybean during kharif season of 2011 at Indian Agricultural Research Institute, New Delhi, to quantify the response of soybean to treatments of flooding, drought and high temperature alone and in five different combinations at different phases of crop growth. Overall results on phenology, biomass accumulation and distribution, yield and yield components indicate that the plants responded differentially to sequential stresses depending on the coincidence of the occurrence of type of stress. The results indicate that in soybean, water is the most important factor determining yield and it can withstand high temperature stress if water is not limiting. In seasons when heavy rainfall events coincide with vegetative growth period followed by dry spells during flowering and then good rainfall events in the pod filling period (PFP) will not affect the crop yield. On the other hand, dry spells during vegetative period significantly reduces the yield.

Abstract
A field experiment was conducted on a sandy loam soil at Krishi Vigyan Kendra, University of Agriculture and Horticultural Sciences, Shimoga, Karnataka during kharif of 2013 in order to investigate the effect of phosphorus levels with or without PSB seed treatment on productivity of groundnut. The levels of phosphorus @ 0, 25, 37.5 and 50 kg P2O5 per ha-1 with or without PSB seed treatment were tried in a randomized complete block design with three replications and eight treatments. Results of the field experiment indicated that seed treatment and higher level of phosphorus significantly increases the growth, yield and yield attributes and uptake of nutrients by groundnut. Groundnut pod, haulm and oil yield were higher in the treatment 50 kg P2O5ha-1 with PSB seed treatment compared to other treatments and was on par with 50 kg P2O5 ha-1 without PSB seed treatment and 37.5 kg P2O5 ha-1 with PSB seed treatment. Highest pod yield of groundnut (24.29 q ha-1) was obtained by application of 50 kg P2O5 ha-1 with PSB seed treatment.

Abstract
A field experiment was conducted during rabi season, 2012-13 to study the influence of plant densities and varieties on yield parameters, yield and economics of groundnut. Groundnut varieties and plant densities showed significant influence on yield parameters such as number of pods per plant, number of kernels per pod, 100 kernel weight (g) and shelling percentage (%), yield and economics of groundnut. Among different varieties tried, TAG-24 produced highest number of pods per plant (15.5) and highest shelling percentage (73.67) at a plant population of 4.44 lakh ha-1. Number of kernels per pod and 100 kernel weight were not significantly influenced by varieties and plant densities. With regard to pod production, haulm yield and harvest index all the varieties produced statistically equal yield. However variation in density of planting resulted in production of significantly lower pod yield with 3.33 lakh ha-1and the rest of the treatments produced statistically equal yield. However higher haulm yield was recorded with 6.66 lakh ha-1. The gross returns, net returns and B:C ratio was cannot significantly influenced by varieties and plant densities.

Abstract
Pineapple disease caused by Ceratocystis paradoxa (De Seynes) Moreau. is one of the most destructive and widespread disease of sugarcane, (Saccharum officinarum) which cause losses of setts germination (12 to 20%) and yield reduction of10 to 15 tonnes/ha. The pathogen/disease is very difficult to manage with chemicals alone and also uneconomical keeping these in mind, present study was undertaken to manage pineapple disease with soil amendments and bioinoculants, constituting a total of 13 treatments evaluated in vitro (plate and pot culture). Results revealed that aqueous extracts of the test amendments and culture filtrates of the test bioinoculants significantly inhibited mycelial growth of the test fungus, over untreated control. However, recorded with Azotobacter diazotrophicus (18.08 mm), followed by neem seed cake (19.91 mm) and cotton seed cake (23.66 mm). All the organic amendments and bioinoculants applied in sick soil (C. paradoxa) were found effective in reducing the pre-emergence setts rot as well as post-emergence seedling mortality in sugarcane cv. Co 86032. The average (PESR + PESM) reduction in mortality recorded with all the organic amendments and bioinoculants tested were ranged from 51.41 to 90.96 percent as against 0.00 percent in untreated control. However, highest average reduction in mortality (90.96%) was recorded with vermicompost + neem seed cake + A. diazotrophicus. Followed by poultry manure + cotton seed cake + A. chroococcum (83.14%) and neem seed cake + A. diazotrophicus (82.14%).

Abstract
The present investigation was carried out at Department of Agrometeorology, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh). Simulation model, with its holistic approach to simulate the soil-plant-atmospheric system, is an ideal tool to analyze the impact of different inputs and to suggest the appropriate package and practices. Keeping in mind the importance of crop simulation models, HERMES model was calibrated in Chhattisgarh conditions. The phenology, LAI, biomass and grain yield simulated by model were compared with that observed in the irrigated condition under field situation. Sensitivity analysis was also carried out in different temperature scenarios by increasing or decreasing daily temperature by 1, 2 and 3°C. Results of the sensitivity analysis showed that while increasing the temperature by 1, 2 and 3°C grain yield increased by 8%, 19 % and 25% under irrigated condition, respectively. While, decreasing the temperature by 1, 2 and 3°C grain yield decreased by 17%, 17%, and 21% under irrigated condition respectively. The grain yields were highly affected by changing the temperature in cultivar ARB-8 of rice crop. The conclusions drawn from this study is that crop growth model are very good tools for analyzing the soil-plant-atmospheric system and their interactions. The crop models can provide a frame work for interpreting the output from field experiments and they can be used to explore ways of improving management. HERMES model could simulate the phenological stages, growth and yield of rice which are in fair agreement with the observed phenological stages, growth and yield.

Abstract
Among biotic constraints, charcoal rot is an important disease of peanut incited by Rhizoctonia bataticola (Taub.) Butler, creating serious problems in farmers field of Chittorgarh and Udaipur districts in Rajasthan, India. For this, isolation, purification and identification were performed and some oil cakes (in vivo) and fungal bioagents were tested in vitro as well as in vivo. In vitro condition, two antagonistic fungi i e T. harzianum and T. viride significantly reduced the mycelial growth 72.12 and 68.80% of R. bataticola respectively. In vivo condition, talc based formulation of T. harzianum and T. viride @ 6g, 8g and 12 g/kg seed as seed treatment were tested and found that T. harzianum @ 12 g/kg seed gave maximum seed germination (96%) and minimum plant mortality (8.33, 18.18, 33.33% respectively) followed by T. viride at 12g which gave 94% seed germination and 8.51, 18.60 and 37.14 % plant mortality at 15, 35 and 70 days after sowing, respectively. While, T. viride at 6g was found least effective. All the oil cakes significantly reduced the occurrence of charcoal rot incidence in peanut. However, neem cake at 2% w/w of the soil was found to be most effective to enhancing seed germination (95%) and reducing disease incidence followed by pongamia at 2% and mustard cake 2% w/w.

Abstract
Sugarcane (Saccharum officinarum) crop has been found severely affected with pineapple diseases caused by Ceratocystis paradoxa, especially at sett germination and initial seedling stage, causing noticeable reduction in final plant stand per unit area and ultimately cane yield losses to the tune of 15 - 20 percent. The pathogen being soil borne and sett borne, preventive measures are of prime importance to manage this pineapple disease (C. paradoxa). Hence present in vitro studies were undertaken. The results obtained on fungicides evaluation revealed systemic fungicides viz Carbendazim, Propiconazole and Hexaconazole with highest average mycelial growth inhibition of 94.44, 94.44 and 91.66 percent, respectively followed by non systemic fungicides Thiram (79.64%) and Captan (77.07%). Among biocontrol agent tested, significantly mycelial was recorded with Trichoderma viride (77.04%), followed by T. harzianum (70.74%) and T. hamatum (69.44%). The all botanical tested, A. sativum was found most fungistatic with significantly highest average mycelial growth inhibition (63.95%), followed by Z. officinale (61.48%) and A. indica (59.75%).

Abstract
The research was carried out to study the correlation and path coefficient analysis of 48 different genotypes for yield and nutritional quality characters. Analysis of correlation between different characters suggested that the magnitude of genotypic correlation were higher as compared to their corresponding phenotypic correlations indicated the inherent relationship among the characters. Seed yield per plant exhibited significant positive association with number of effective branches per plant, number of pods per plant and harvest index at both genotypic and phenotypic levels. Path co-efficient analysis revealed that the highest positive direct effects for number of effective branches per plant and number of pods per plant towards seed yield. This finding suggested that more emphasis should be given to number of effective branches per plant and number of pods per plant in selection programmes aiming to improve seed yield in chickpea.

Abstract
An investigation was carried out in Tamil Nadu Agricultural University, Coimbatore during winter seasons of 2012-13 and 2013-14 under irrigated condition to study the influence of crop geometry and drip fertigation on growth and yield of Bt cotton hybrid. The experiment was laid out in a strip plot design and replicated thrice. The treatments comprised of four levels each of crop geometry and fertilizer application. The crop geometry consisted combination of two inter row spacings (120, 150 cm) and two intra row spacing (60, 90 cm) while the major nutrients were applied at 75 percent (S1), 100 percent (S2) and 125 percent (S3) of recommended fertilizer by drip fertigation and the fourth is conventional practice of fertilizer application. Among the crop geometry 120 × 60 cm recorded better growth and yield while application of fertilizer dose of 125% RDF as WSF was found to be optimum higher yield and it was on par with application of 100% RDF. From two years experimentation it can be concluded that adapting the crop geometry of 120 × 90 cm and applying 100 percent recommended fertilizer (150:75:75 kg ha-1) in water soluble form (75% of P as super phosphate and 25% as WSF, 82.5% of N as urea and 17.5% as potassium nitrate and mono ammonium phosphate) through drip irrigation system and also recorded higher net return and B:C ratio.

Abstract
A field experiment was conducted during kharif 2014 to study the influence of different levels of nitrogen and planting patterns on growth and yield of maize. The experiment was conducted with three levels of nitrogen and six planting patterns. Taller plants were produced by 300 kg N ha-1 which was statistically superior over 200 and 250 kg N ha-1. Progressive increase in LAI and dry matter production (kg ha-1) and yield attributes like cob length (15.8 cm), cob girth (14.6 cm), number of grains per row (27.3) and 100-grain weight (32.67 g) was observed due to increased nitrogen levels from 200 to 300 kg ha-1. Number of rows per cob, shelling percentage and harvest index were not significantly influenced by nitrogen levels. Application of 300 kg N ha-1 produced higher cob, grain and stover yields and also higher net returns than other levels (200 and 250 kg N ha-1). Highest plant height, maximum leaf area index and dry matter production was higher with equidistant row planting at 75 cm on ridges (P2) which was at par with equidistant row planting at 75 cm in flat bed with formation of ridges at 20 DAS (P3) and paired row planting on ridges at 45 cm and between paired rows with 105 cm gap (P5). However with regard to yield parameters higher cob yield, grain yield and net returns were obtained with P2 which was superior over flatbed planting methods (P1 and P4).

Abstract
The present investigation was conducted at Fruit and Vegetable Processing Laboratory of Department of Horticulture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during the month of June-July, 2014. Matured freshly harvested mango fruits of uniform size were treated with different treatments as post harvest dips for 10 minutes. Then fruits were wrapped with wrapping materials and kept in Corrugated Fiber Board (CFB) boxes at ambient temperature. The fruits treated with different plant extracts and wrapped in different wrapping materials, showed lower and slower rate in physical and chemical changes than control fruits. The fruits dipping in adusha green leaf extract 5% (D4) and brown paper wrapping treatment were found superior with highest number of marketable ripe mango fruits, lowest number of unmarketable ripe mango fruits, higher sugar content, slower increase in TSS, while slower decrease in ascorbic acid and acidity during storage as compare to control (plain water dipping) and chemical treatment (ethylene 750 ppm) and no wrapping of fruits. In respect to interaction effect of treatments, T20 (D4 × W5) adusha leaf extract 5% dipping with brown paper wrapping was found significantly superior for various parameters.

Abstract
In the present study, 121 linseed genotypes consisting of high yielding linseed varieties from NBPGR, Germplasm Exchange Division, New Delhi, University of Agricultural Sciences Raichur, Karnataka and CSK Himachal Pradesh Krishi Vishwavidyalaya, Palampur, H.P. These germplasm lines were raised at MARS Dharwad during rabi 2012 to identify diverse genotypes. They were evaluated for eight yield and yield attributing characters using D2 analysis, to study the diversity pattern among the genotypes. Based on the analysis, the genotypes were grouped into 15 clusters. Maximum number of 36 and 34 genotypes were grouped under cluster I and II respectively, while cluster IV, III and VI having 21, 14 and 4 genotypes respectively. Cluster VIII and XV had two genotypes each. Further clusters V, IX, X, XI, XII, XIII and XIV were found to have one genotype each. Maximum inter cluster D2 value was observed between cluster III and cluster VIII (55.87) followed by cluster VII and VIII (55.01). The greater the distance between the two clusters indicates wider the genetic diversity between genotypes. Hence, the genotypes in cluster III viz EC-1543,EC-1475, EC-41762, IC-53294, SURBHI, IC-96559, EC-41623, IC-53279, IC-53291, EC-41755, HIM ALSI-2, IC-96594, HIM ALSI-1 and IC-53292 had wider diversity with varieties PKV and NL-97 in cluster VIII. These lines may be utilized in further breeding programme for the exploitation of maximum hybrid vigour. The intra cluster distance was maximum in cluster IV (D = 12.32), followed by cluster III (D = 11.27) and cluster II (D = 11.1) indicates hybridization involving genotypes within the same clusters may result in good cross combinations. Among the ten traits studied, maximum contribution was made by number of capsule per plant in each genotype showed highest contribution (41.09%) followed by oil yield per plant, (16.35%), 1000 seed weight (13.02%), seed yield per plant (11.07%). Hence, number of capsule per plant, oil yield per plant, 1000 seed weight and seed yield per plant contributed 81.53 percent towards total divergence. Therefore, these characters may be given importance during hybridization programme.

Abstract
Red chillies throughout the world are used as spice on account of their pungency, fascinating red colour and distinct flavour. Chillies exhibit different shades of red colour and fruits having shining blood red colour fetch the highest price. The arbuscular mycorrhizal fungi (AMF) and some phosphorus solubilizing bacteria like Pseudomonas can be instrumental in obtaining phosphorus from organic matter and mineral forms by increasing the diffusion zone around roots and by the production of phosphatase enzymes. The dual inoculation of Glomus macrocarpum and the best compatible biocontrol agent, Pseudomonas fluorescens to be a superior consortium of microorganism for inoculating Capsicum annuum. Inoculation with such a microbial consortium results in healthy and vigorously growing chilli crop. This technology, being simple and eco-friendly can be adopted easily by any farmer.

Abstract
Salinity is one of the severe environmental stresses which impair rice production. The present study focused on effects of salinity on chlorophyll content and growth parameters in different salt concentrations that is 0 (control), 60Mm NaCl and 120mM NaCl in rice genotypes. Increase in the levels of salinity led to a reduction in the chlorophyll a, b and ultimately in total chlorophyll content. Besides, there was a reduction in seedling length also. The genotypes Swarnamukhi and Vikas exhibited better survival response to salinity. Tolerant genotypes showed lower reduction in SPAD and total chlorophyll contents. Fresh weight reduced with increase in salinity level irrespective of genotypes; however the reduction was lesser in tolerant genotype than sensitive genotype.

Abstract
The effect of different sowing dates on late leaf spot of three groundnut cultivars was studied in relation to weather parameters. Disease severity was significantly influenced by the time of sowing and cultivars, which directly affected the pod yield and test weight in groundnut. The mean disease severity was found to be maximum on the crop sown on 1st July followed by the crop sown on 15th June, 16th July, 1st August and 16th August. Among three cultivars of groundnut, Cv. JL-24 was found most susceptible with maximum severity followed by TLG-45 and TAG-24 which found moderately resistant to the disease. The early sown crop was found to suffer more with the late leaf spot disease compared to the crop sown later. These may be due to the congenial environmental conditions and high inoculum load available during month of August and September.

Analysis of twelve characters under study viz days to 50% flowering, number of primary branches/plant, number of capsules/plant, capsule size, number of seeds/capsule, seed weight, days to maturity, biological yield, harvest index and seed yield/plant exhibited existence of variability significant at 1% significant level, whereas plant height had significant at 5% probability level and seed size was not significant. This indicated existence sufficient variability among the genotypes for the mentioned characters and sufficient scope for development of genotypes. The high phenotypic coefficient of variation and genotypic coefficient of variation were recorded for seed yield/plant followed by number of primary branches/plant harvest index, number of capsules/plant. High heritability estimates were recorded for plant seed yield/plant followed by number of seeds/capsule, harvest index, seed weight and number of primary branches/plant. The present investigation revealed that high heritability with high genetic advance were recorded for the characters viz seed yield/plant, followed by harvest index, seed weight, days to maturity, biological yield. Selection for these traits is likely to accumulate more additive genes leading to further improvement of performance of genotypes.

Abstract
The relationship between environmental factors viz air temperature, soil temperature, relative humidity, rainfall and sunshine, cloudiness and development of disease was studied during kharif 2010 and 2011. It was found that increase in air as well as soil temperature favours the development of disease. The coefficient of correlation worked out between maximum, minimum and mean temperature of air and soil and plant mortality was positive with values of 0.547, 0.814, 0.939 and 0.190, 0.796, 0.906 and 0.810, 0.920, 0.906 and 0.961, 0.993 during 2010 and 2011, respectively. The plant mortality of groundnut was maximum (28.20 and 29.80%) when the air as well as soil temperature was maximum (34.30°C, 29.50°C and 39.15°C, 34.40°C) in both the years 2010 and 2011. However, high relative humidity didn’t favours the disease development and when relative humidity was lowest (41.5 and 63.15%) then the disease development was highest (28.20 and 29.8%). The coefficient of correlation between disease development and relative humidity was negative but non-significant during both the years. Rainfall did not show any specific pattern on the disease development. However, the coefficient of correlation was positive but non-significant. It may affect the soil moisture and ultimately the development of disease which was maximum in moisture stress condition.

Abstract
An experiment was conducted to study the possibility of enhancing the arbuscular mycorrhizal fungi root infection in the co inoculation of Methylobacterium sp. isolates obtained in the present study. The experiment was carried out with methylobacterial isolates such as Methylobacterium sp. LE1, Methylobacterium sp. AI1 were co inoculated with AM fungi to find out mycorrhizal root colonization on tomato plant. From the above findings, treatment such as T5 (Methylobacterium sp. LE1 + AM fungi ) followed by T6 (Methylobacterium sp. AI1 + AM fungi) responding better for combined inoculation which resulted in a significant increase in shoot length, root length, chlorophyll content compared to untreated control plants. In addition the combined inoculation of (Methylobacterium sp LE1 + AM fungi) resulted in significantly higher nutrient uptake of plant compared to uninoculated controls. A perfect mutualism among Methylobacterium sp LE1, AI1 which was co inoculated with AM fungi was found to improve growth parameters, enhancing nutrient uptake and achieving high yield.

Abstract
Response of GA3 and it combination with urea phosphate and BA on berry chemical parameters in grape cv. Thompson seedless was evaluated. Ten treatments of GA3 in combination with urea phosphate and BA at different concentrations and control (water spray) were applied at two stages that were pre bloom and berry set. All the bioregulator and chemical treatments proved effective in improving berry chemical parameters over control. Among all the treatments, application of 40 ppm GA3 at pre-bloom and again at berry set stage proved more effective in enhancing fruit chemical parameters such as TSS, Titrable acidity, total sugars and sugar acid ratio. This it may be concluded that the application of plant growth regulators viz GA3, BA and a chemical urea phosphate at pre-bloom and berry set stages influenced the berry chemical parameters and storage changes after 7 days under ambient conditions.

Abstract
The occurrence of post-harvest fungal pathogens on fruits is becoming a serious problem in humid climatic conditions, particularly in transit and storage. The post harvest fruit fungal pathogens particularly Penicillium, Rhizopus, Aspergillus and Alternaria are predominant and more damaging. The use of probiotics against plant pathogens is altogether a new concept of the authors and therefore in vitro effect of probiotics on post harvest fruit fungal pathogen was assessed by two assessment techniques. It was evident that dual culture broth technique was most effective to assess the efficacy of probiotics against the post-harvest pathogens. However the disk assay method was not found effective to assess the antagonist activity of probiotics against the post-harvest pathogens. The commercial probiotics Darolac, Sacro and Sporocheck inhibited the growth of post-harvest pathogens Penicillium and Alternaria, but could not inhibit the growth of post-harvest pathogen Rhizopus. However, the MPKV probiotic was effective in inhibiting the growth of Penicillium, Rhizopus, Aspergillus and Alternaria.

Abstract
Simarouba (Simarouba glauca L.) belongs to the family Simarubaceae. It grows very rapidly in different climatic conditions. The nutlets contain about 40% kernel. Kernels contain 55-65% oil. Simarouba is one of the promising bio-fuel trees which have a potential to become a new source of bio-oil. The oilcake which is rich in nitrogen (8%), phosphorus (1.1%) and potash (1.2%) is good organic manure. The shells of the simarouba are very hard and difficult to break. The present method involves the breaking of the nutlets by hand beating with stone bars or metal rods, by keeping the nutlet on a hard surface. This method is tedious and time consuming. Manual decortication of nutlets causes delay in obtaining the kernels. To overcome above problem the decorticator was developed it consists of a rocking type threshing bar with a concave. Two types of threshing bars used namely peg tooth and rasp bar. Three threshing bars are attached to two flats in a semicircular shape to establish shear and compression force to the nutlets. The study showed that the nutlets of 4% m.c. with the peg tooth type of threshing bar having a clearance of 7 mm, provided a higher decortication efficiency of 93.8% and had a capacity of 6.6 Kg/h with a better whole kernel recovery.

Abstract
Curvularia leaf spot is a major disease of maize. It causes 20-60 percent yield loss. Since many species of Curvularia are involved in causing curvularia leaf spot of maize, so study was conducted to know the etiology of curvularia leaf spot. The pathogenicity of the fungus was proved and based on the morphological characters the pathogen was identified as Curvularia lunata (Wakker) Boedijn. The percent spore germination of Curvularia lunata was studied on four treatments at different time intervals. Significantly maximum conidial germination (98.33%) was recorded in both sucrose solution and host leaf extract after 12 hours of incubation period which was followed by tap water (94.33%) and the minimum spore germination was recorded in distilled water (91.00%). Among all the treatments tested sucrose and host leaf extracts were found to be the best for spore germination.

Abstract
Ever increasing population especially in developing countries like India require alternate available sources of energy and nutrition. Production of traditional leguminous crops in these countries has not adequately met the energy and nutritional requirements of growing population. Exploitation of wild or under exploited legumes is necessary to combat Protein-Energy-Malnutrition (PEM). Hence, this study has been under taken to assess the available genotypes of Jack bean an underexploited vegetable crop for their nutritional quality at NBPGR Regional station, Rajendranagar during kharif 2013 (August 2013 to February 2014). The results revealed that significant differences were observed among the genotypes for all the nutritional characters studied. Out of fifteen genotypes, PSR 12202 was found superior in terms of protein (20.80%), magnesium (0.36%), calcium (0.75%), sodium (0.07%) and potassium (4.22%) content followed by NS/2009/053 for protein (20.7%) and phosphorus (0.29%) content while, the genotype IC-32881 was recorded highest iron (100.80 mg kg-1) content. Among the genotypes studied NS/2009/053 and RJR-529 were superior in terms of seed length, seed breadth, seed thickness and 100 seed weight. Hence, these superior genotypes may be further tested in multi location trials and can be recommended for commercial cultivation to meet the nutritional requirement.
