Abstract: Sclerotinia sclerotiorum (Lib.) de Bary is soil borne, necrotropic fungal pathogen causes stem rot disease in all Brassica species depending upon the stage of plant growth and environmental conditions in Haryana state. The experiment was carried out to find out the relationship between growth stages and Sclerotinia rot infection in different Brassica species under artificial inoculated conditions at research area of Oilseeds Section, Department of Genetics and Plant Breeding, Chaudhary Charan Singh Haryana Agricultural University, Hisar during rabi 2013-14. Significant variations among different Brassica species were observed for stem rot disease severity as well as days to stem breaking, when inoculated at different stages of plant growth. Maximum disease severity ranging between 80.0-93.3 per cent was recorded in Brassica rapa var. Brown sarson, B. rapa var. Yellow sarson and B. rapa var. Toria genotypes, when 50 days old plants were inoculated as compared to 60 and 70 days old. B. juncea, B. nigra and B. alba genotypes showed maximum disease severity ranging between 40.0- 73.3 per cent, when 60 days old plants were inoculated as compared to 50 and 70 days old. While, in B. napus and B. carinata genotypes, when 70 days old plants were inoculated, showed maximum disease severity ranging between 76.7-81.7 per cent as compared to 50 and 60 days old plants. Early stem breaking ranging from 20.7- 30.0 days after inoculation was observed in B. juncea, B. nigra and B. alba respectively, when 60 days old plants were inoculated. A delay of 10 days in stem inoculation resulted in delay of 7-9 days to stem breaking. It has been concluded that different Brassica species have different congenial growth stages for artificial inoculation under field conditions.

Abstract:In gladiolus, based on Mahalanobis’s D2 analysis, the genetic divergence studies were conducted in twenty genotypes and they were grouped into five divergent clusters. Among all the characters, the most important character contributing to divergence was diameter of corm followed by weight of the spike and weight of corm. Among the grouped five clusters, cluster I was the largest group comprising of 13 genotypes followed by cluster IV of 4 genotypes and all other cluster comprises of single genotype in each cluster. Intra cluster distance was highest in cluster IV (93.99) followed by cluster I (58.44).The inter cluster D2values were maximum (244.37) between cluster I and IV. The minimum distance observed between cluster II and III (52.92). The genotypes Arka Kesar from cluster II, Tilakfrom cluster III and ArkaAmar,Arka Gold,Arka Naveen, Sagar from cluster IV, respectively deserve to be to be considered as potent parents for further utilization in gladiolus improvement programme.

Abstract:Eighteen kilometer stretch of Yamuna River studied by measuring various physicochemical parameters of water quality during pre-monsoon and post-monsoon 2014. River Yamuna, during its flow through Sirmour district in Himachal Pradesh receives domestic and industrial effluents from different villages and Ponta-sahib industrial hub situated on its banks. Depending upon the location of point sources of industrial effluent discharges, eight sampling stations were selected for collecting the water samples. Maximum pH (7.95±0.03), EC (304.32±0.16) ìmhos/cm, TDS (88.91±1.08) mgL-1, BOD (15.24±0.01) mgL-1, COD (29.79±0.04) mgL-1, Fe (0.220±0.0) mgL-1 and Zn (2.760±0.0) mgL-1 was observed in pre-monsoon, whereas maximum, turbidity (27.17±0.02) NTU was recorded in post-monsoon season. There was significant increase in all parameters from the upstream of Pontasahib municipal and industrial town to the downstream Satiwala (station 1 to 8). All the parameters were within the permissible limits of drinking water standards except BOD and COD. The BOD values at all the monitoring stations, were higher compared to 5 mgL-1. The maximum value of BOD (15.24±0.01) mgL-1 and COD (29.79±0.04) mgL-1 was observed at a distance of 18 km at Satiwala village (S8) during pre-monsoon season. Based on the results of BOD and COD stretch of the river can be categorized as class of stream ‘D’ for which the designated best uses are propagation of wild life fisheries, irrigation, industrial cooling and controlled waste water disposal. It can be ascribed to the discharge of untreated domestic waste, industrial effluents at the upstream of all the monitoring stations and urban runoff from industrial hub.

Abstract: The field experiment was conducted at main agricultural research station, UAS, Dharwad during kharif season of 2013 to study the effect of chemical defoliator application on yield and economics of compact cotton genotypes. Treatments consisted of 12 combinations comprising of two genotypes (G1-RAH 274 and G2-SC 2028 22) as main plots, two spacing levels (S1:45x10 cm and S2:45x15 cm) as sub plots with three chemical defoliator (D1: Dropp Ultra @ 200 ml/ha, D2: Ethrel @ 2000 ppm and D3: Water spray) as sub sub plot treatments. Results revealed that genotype RAH 274 with spacing of 45x15 cm along with application of chemical defoliator Ethrel @ 2000 ppm recorded higher seed cotton yield (2241 kg/ha), gross returns (Rs. 100830/ha), net returns (Rs. 67910/ha) and B C ratio (3.06) over other interactions. Similarly, the same interactions recorded higher yield attributes viz., sympodial branches per plant, number of bolls per plant, per cent boll open and yield per plant which resulted the higher seed cotton yield and economic returns. However, this treatment with spacing of 45x10 cm recorded significantly higher leaf defoliation (99.8 %) and superior over others.

Abstract: The field experiment was conducted under South Gujarat conditions to evaluate the effect of spraying of water soluble fertilizers on growth, yield and economics of okra production. The experiment comprised of seven treatments with spraying of water soluble fertilizers and each were applied thrice at 30, 45 and 60 DAS. Among the different treatments tested, three sprays of banana pseudostem enriched sap @ 1 % or mixed fertilizer (19:19:19 @ 0.5%) resulted in achieving higher plant height, number of fruits per plant, yield per plant, dry fruit yield, dry plant yield and commercial green fruit yield in okra. From the economics point of view, for securing maximum return, an application of enriched sap (T6) was found superior with the highest BCR of 3.6:1. Both these treatments (T1 and T6) were found economical, profitable and proved highly remunerative for okra production.

Abstract: The present study was aimed to evaluate the economic feasibility of growing organic tomatoes under farmer’s conditions in mid hill conditions of Himachal Pradesh. The budget identifies specific cost categories and estimates a net return for the production and sale of organic tomato crop. Therefore, in this study, cost effective methodology for organic fruit and seed production of tomato was developed. It was observed that highest cost of production for fruit and seed yield (Rs.1,15,934 and Rs.1,20,034, respectively) and maximum gross income (Rs.3,90,449.01 and Rs.2,09,601.67, respectively) were observed in the treatment ’T7' (Vermicompost + Biofertilizers). However, maximum net returns for fruit and seed yield (Rs.2,99,384.87 and Rs.1,17,984.01, respectively) and benefit: cost ratio (3.60:1 and 1.35:1, respectively) were recorded in treatment ’T9' (Biovita + Biofertilizers), whereas lowest cost of production (Rs.77,934), gross income (Rs.1,79,348.67), net returns (Rs.1,01,414.67) and benefit: cost ratio (1.30:1) for fruit yield were observed in the treatment ’T10' (Control).Therefore, treatment ’T9' from economic point of view and treatment ’T7' for retention of soil fertility year after year and getting high fruit and seed yield, can be recommended for commercial cultivation of tomato in hilly regions of the country.

Abstract: The present study was conducted using 19 genotypes of wheatunder sodic soil conditions during the crop season of 2012-13. These genotypes were evaluated for ten characters. Grain yield per plant showed highly significant positive correlation with biological yield per plant and significant positive correlation with number of effective tillers per plant followed by number of grains per spike, number of spikelets per spike and harvest index at phenotypic level. The estimates of genotypic correlation coefficient were generally similar in sign or nature but higher in magnitude than the corresponding phenotypic correlation coefficient. At phenotypic and genotypic levels, grain yield per plant had strong and positive association with biological yield per plant followed by number of effective tillers per plant, number of grains per spike, number of spikelets per spike and harvest index. Based on the results, it is reasonable to assume that high yield of wheat in these genotypes could be obtained by selecting breeding materials with number of effective tillers per plant, number of grains per spike, number of spikelets per spike and biological yield per plant.

Abstract: Flaxseed is cultivated in many parts of world for fiber, oil as well as for medicinal purposes and also as nutritional product. It is a native of Egypt but also cultivated in India, Holland, Russia and Britannia mainly for the purpose of its oil and fiber and is best adapted to fertile, fine textured, clay soils. Flax was valued in Ancient and Early Modern times as both a food and medicine. In this review, nutrients, anti-nutrients, functional properties and health benefits of bioactive molecules viz., essential fatty acids, lignans and dietary fiber of flaxseed are discussed. Flaxseed contains good amount of á-Linolenic Acid (ALA), omega-3 fatty acid, protein, dietary fiber, lignan specifically Secoisolariciresinol diglucoside (SDG). ALA is beneficial for infant brain development, reducing blood lipids and cardiovascular diseases. Researchers reported that flaxseed incorporated food products can have good consumer acceptability along with its nutritional benefits.

Abstract: Ten genotypes and forty five F1sof bread wheat were evaluated in randomized block design (RBD) with three replications for yield and yield contributing traits during rabi 2013-2014, to find out the genetic variability, heritability and genetic advance percent of mean. Analysis of variance revealed significant differences among treatments for all the trait. This indicated the presence of significance variability (both genotypic and environmental) in the present set of material which allowed for conducting further genetic analysis. PCV values were higher than GCV values for all the traits which reflect the influence of environment on the expression of traits. Highest PCV and GCV observed for peduncle length 8.58 and 8.41 respectively. All the characters except tillers/ plant, biological yield/plant, and economical yield/ plant in the present investigation indicated high heritability. High heritability indicates the scope of genetic improvement of these characters through selection. All the traits under study showed low genetic advance. Most of the character exhibited high heritability along with low GAM indicated the presence of non-additive gene action.

Keywords: Wheat, Genetic variability, Heritability and genetic advance

Abstract: An experiment was carried out during kharif 2012 to evaluate genetic diversity among 100 differentially adopted cultivated rice genotypes including 4 standard check varieties (Sarjoo-52, NDR 359, PB- 1 and CSR 30). Analysis of variance showed highly significant differences due to treatments for all the characters. Observations were recorded fourteen distinct agronomic traits.The non-hierarchical Euclidean cluster analysis grouped one hundred four genotypes into eleven distinct clusters. This indicated existence of high degree of genetic diversity in the genotypes evaluated. The eleven clusters formed in divergence analysis contained genotypes of heterogeneous origin thereby indicating no parallelism between genetic and geographic diversity. Therefore, crosses between the member of cluster separated by high inter cluster distance are likely to throw desirable segregants. In this context cluster IX had very high inter cluster distance from clusters IV, II, X, XI and III. Thus, crosses between promising lines belonging to cluster pairs having high inter-cluster distance may be attempted for isolating transgressive segregants.

Abstract: The present experiment was initiated to examine the effect of osmopriming on rice seed attributes after accelerated ageing. Rice variety BPT-5204 was taken to evaluate the effect of osmopriming on its germination, vigour, viability and biochemical properties. Inorganic Chemical namely ZnSO4, PEG (Phosphoenoleglycolate), KNO3 (potassium nitrate), KH2PO4 (potassium artho phosphate) and Salicylic acid were used. The result revealed that the seeds osmopriming with 1% ZnSO4 recorded higher seed germination(82.70%),seedling length (32.37cm),seedling vigour index I (2677) and seedling vigour index II (438) priming after accelerated ageing treatment. Seed storage proteins were degraded in the artificially ageing process and Osmopriming of artificially aged seeds may be responsible for reversing effects of artificial ageing.

Abstract: The pesticide are a group of chemicals refers to a group of insecticides or nerve agents acting on the enzyme acetylcholinesterase, intended for preventing/destroying any pest detrimental to man during production, processing, storage, transportation and distribution of food. Acetylcholinesterase enzyme leads to a pathologic excess of acetylcholine in the body. Hundred samples including twenty samples of each vegetables viz. cauliflower, brinjal, okra, tomato and cabbage were collected from various markets of Kanpur City. For pesticide residues analysis on gas liquid chromatography (GLC), the samples were processed, extracted as per standard methodology. Analysis showed that all the vegetables samples are either totally or partially contaminated with organophosphate. All the detected samples were found below their maximum tolerance limit (MRL). So, these samples are safe to the consumers and environment. But monitoring studies on vegetables for pesticides residue should continue on uniform pattern for safety in future.

Abstract: Rainfall determines the potential of any region in terms of crops to be grown, farming system to be adopted, the nature and the sequence of farming operations to be done. On an average 9.62 % of cultivated area of Dediapada taluka (Dist. Narmada) is under irrigation, remaining 90.38 % area is under rainfed agriculture (Annual Progress report: 2011-12, KVK, NAU, Dediapada). The amount of rainfall received by the region is sufficient for rainfed farming in Kharif season. Morris and Zandstra (1979) criteria and Raman (1974) criteria of onset and withdrawal of effective monsoon have been used for estimating the most suited SMW (Standard Metrological Week) for commencement of sowing operation, requirement of supplementary irrigation during rainfed crop and withdrawal of Monsoon. For maximum one-day rainfall analysis, observed rainfall values have been obtained from Weibull’s formula while the expected rainfall values have been estimated by using frequency factors for the different probability distributions i. e. Normal, Log-Normal, Pearson type III, Log-Pearson type III and Gumbel distribution. 27th SMW receives sufficient rainfall for commencement of sowing operations. There are 75 % and 60 % probability to get minimum 10 mm for continuous 77 days (27th to 36th SMW) and minimum 20 mm rainfall for continuous 9 SMW (27th to 35th) respectively. Supplementary irrigation is not required during the period. Log-Pearson type –III distribution is best fitted among all the five distributions as it gives lowest chi-square value i. e. 22.83. Maximum one-day rainfall for different returns periods from Log-Pearson type III i. e. 5, 10, 15, 20, 25, 50 and 100 years are respectively 189, 245, 280, 307, 329, 405 and 493 mm. Which can be used to design various conservation measures for watershed development planning.

Abstract: Genetic variability, heritability and genetic advance were estimated for various quantitative characters in fifty genotypes of chickpea over three different environments. Analysis of variance revealed significant differences among the genotypes for all the characters studied. The highest GCV and PCV were observed for number of branches per plant followed by 100 seed weight, number of pods per plant, seed yield per plant, biological yield per plant. The highest heritability value was registered for protein content (%), plant height, days to 50% flowering, seed yield per plant, biological yield per plant. Genetic advance as % of mean was highest for 100 seed weight in E1 and E2 followed by seed yield per plant for number of pods per plant in E3 followed by number of branches per plant, harvest index and seed yield per plant. In the present study high heritability estimates accompanied with high genetic advance were observed for 100 seed weight in all the three environments hence this is the most important characters for improving the genotype

Abstract: An experiment was laid out at Student’s Instructional Farm of Narendra Deva University of Agriculture and Technology, Narendra Nagar, Kumarganj, Faizabad (U.P.) during Rabi season of 2011-12. The experimental materials comprised of 144 diverse genotypes of chickpea were evaluated for 11 quantitative characters. The high PCV and GCV were observed for number of pods per plant followed by seed yield per plant and 100 seeds weight, indicating that these traits were main yield contributing characters. High heritability estimates were observed for 100 seeds weight, days to 50% flowering, plant height, number of seeds per pod, pods per plant and seed yield per plant. The expected genetic advance as per cent of mean was high for number of pods per plant, 100 seeds weight, seed yield per plant and number of seeds per pod. The high heritability coupled with high genetic advance as per cent of mean for 100 seeds weight and number of pods per plant would be helpful for indirect selection for improvement in seed yield.

Abstract: The present investigation was carried out in the two consecutive years i.e. 2011-12 and 2012-13 at Main Experiment Station, Department of Horticulture, NDUA&T, Faizabad, (U.P.). The experiment was conducted in RBD replicated four times with twelve treatments. The treatments involved in the study were 12 in numbers i.e. FYM in six different doses (0, 05,10,15,20 and 25 t/ha) and nitrogen through Urea in six different doses (0, 25, 50, 75,100 and 125 kg/ha). Among the FYM doses, FYM (25 t/ha) had more pronounced effect on plant height and number of primary branches. The maximum plant height (75.77cm) and number of primary branches per plant (12.90) were noted with application of FYM @ 25 t/ha followed by application of Urea @ 125 kg/ha (74.21cm and 7.2 respectively) and minimum in control (58.15 cm and 7.2 respectively). Whereas, FYM (20 t/ha) increased number of secondary branches per plant (30.41) followed by application of Urea @ 100kg/ha (29.02). The highest fresh and dry biomass at flowering bud initiation stage (41.91 kg/ha and 9.25 kg/ha) were observed with application of FYM @ 20 t/ha.

Abstract: The experiment was done to assess the effects of different concentrations i.e. Lethal Concentration (LC5), Lethal Concentration (LC50) and Lethal Concentration (LC95) of Potassium Permanganate on hydrological parameters of water.Analytical grade Potassium Permanganate (KMnO4) of Merck India Ltd. was used for the experiment. The toxicity bioassay of Potassium Permanganate (PP) was conducted separately for 2hr, 3hr and 4hr of exposure to the fingerlings of Clarias gariepinus in controlled laboratory conditions. The mortality percentage of the test organisms were recorded after every one hour of exposure. Two types of bioassay i.e.Range Finding Bioassay & Lethal Toxicity Bioassay was conducted to get the 100% mortality of the test fish.Lethal Concentrations (LC) of this toxicant at which the test organisms died (LC5 to LC95) was calculated by the method of EPA Probit Analysis Program (Version 1.5). Impacts of Potassium Permanganate on different hydrological parameters like Temperature, pH, Conductivity and Dissolved oxygen of test water were recorded after every 1hr of interval. It was observed that the pH, DO of water increased but conductivity of water decreased after application of KMnO4 and Temperature of test water was not varied significantly (P>0.05) during the experiment. It was also concluded that it should not be recommended as an ideal Piscicide and its applications as disinfectant, therapeutants and prophylactic are strongly encouraged.

Abstract: Enzyme dynamics and soil properties in soil amended with levels of urea, DAP and FYM in aerobic and flooded ecosystems was conducted in a red sandy loam soil in eastern dry zone of Karnataka. The nutrient status of the study site was low in organic carbon (3.4 g kg-1), nitrogen (168 kg ha-1), phosphorus (13.84 kg ha-1) and potassium (174 kg ha-1). The experimental design used wasRCBD with 7 treatments viz., 150 % RDF, 100 % RDF+FYM @ 10 t ha-1, 50 % RDF+5 t ha-1FYM, urea at 100 % N equivalent, DAP at 100 % N equivalent, FYM at 100 % N equivalent and absolute control. The test crop was rice hybrid, KRH-2. The results revealed that addition of 100 % RDF+FYM@ 10 t ha-1 recorded a significant increase in enzyme activities (urease, phosphatase and dehydrogenase) throughout the crop growth period over control in both aerobic and flooded ecosystems. Between ecosystems enzyme activities were higher in aerobic system than flooded system. All the enzymes showed significant and positive correlation with organic carbon, available nitrogen, phosphorus and potassium.

Abstract:On the basis of overall lowest mean percentage of leaf infestation 10.70% of L. trifolii recorded in the plots treated with NSKE (5%) followed by tobacco extract (5%) 11.77% and NSKE (2%) 22.09%. However, treatments, NSKE (5%), tobacco extract (5%) and NSKE (2%) were observed significantly less 2.11, 2.62 and 4.52 flies/10 cm twig B.tabaci population, respectively as compared to rest of the treatments. Treatments, NSKE (5%), tobacco extract (5%) and NSKE (2%) were observed significantly less 1.60, 2.07 and 3.21 A. devastans populations per six leaves, respectively and NSKE (5%) and tobacco extract (5%) were also observed significantly less 2.84 and 3.67 per six leaves A. gossypii population, respectively. The treatments, NSKE (5%) and tobacco extract (5%) were observed significantly less larval population of H. armigera 1.21 and 1.57 larvae/plant, respectively. The average less percentage of fruit damaged (6.71 % and 10.97 %) and less percentage yield loss (20.38 and 23.25 %) were recorded in NSKE (5%) and tobacco extract (5%) treatments and considered the most effective treatments against H. armigera. On the basis of above results, NSKE (5%) and tobacco extract (5%) were most effective treatments against L. trifolii, B. tabaci, A. devastans, A. gossypii and H. armigera. NSKE (2%) (16.99 %) and tobacco extract (2%) (17.84%) were found moderately effective than other treatments in respect of less percentage of damaged fruits. Treatment, NSKE (5%) was recorded significantly highest fruit yield 147.50 q/ha. Followed by tobacco extract (5%) (135.57 q/ha.) than rest of the treatments. On the basis of overall performance and economics of these different phyto extracts, NSKE (5%) and tobacco extract (5%) were most effective treatments against the major insect pests of tomato. NSKE (5%) & tobacco extract (5%) gave highest net return (Rs. 47915 & 42700/ ha.) with C: B ratio of 1: 3.70 and 1:3.50, respectively.

Abstract:An investigation was carried out with 126 genotypes of forage sorghum at instructional farm of Rajasthan College of Agriculture, Udaipur during summer 2013 to asses association of fodder yield components and their direct and indirect effects on green fodder yield per plant conducted. It was observed that the green fodder yield I cut was significant and positively correlated with dry fodder yield I cut both at genotypic (0.89) and phenotypic (0.66) level. The phenotypic correlation of green fodder yield I cut was also significant with dry fodder yield per day (0.66), leaf: stem ratio (0.28) and leaf breadth (0.26) in positive direction and with protein percent (-0.26) and total soluble solids (-0.24) in negative direction. The green fodder yield II cut was significant and positively correlated with dry fodder yield per day II cut at both genotypic (0.99) and phenotypic (0.99) level. The phenotypic correlation of green fodder yield II cut was positively correlated with leaf: stem ratio (0.30) and significant negatively correlated with early vigor (-0.20). Correlation between these characters was also in same direction. Path coefficients for green fodder yield at I and II cut were computed using genotypic correlation between characters recorded independently and having significant difference between genotypes. The 14.15 % variability of green fodder yield I cut and 8.86 % variability of green fodder yield at II cut was explained by these 4 and 9 characters respectively. Maximum direct effect was leaf stem ratio followed by total soluble solids, leaf breadth and protein per cent towards green fodder yield I cut and leaf: stem ratio, regeneration ability, stem diameter, number of leaves per plant and total soluble solids towards green fodder yield II cut. Hence these characters may be considered as selection indices in sorghum breeding programme.

Abstract: In the present study the role of catalase activity and chlorophyll content were examined at 60 and 90 days in salinity as well as control condition in leaves of rice genotypes. The levels of salt stress with EC=12 dS m-1, were used in a randomized complete block design with three replications under net house conditions.Salinity treatment was started from 21 days to maturity and maintained at EC=12 dS m-1 at pH=5.Tolerant genotypes were Pokkali and Nonabokra followed by NUD-3, FL-478, CSR-13, NUD-2, CSR-30 and CSR-90-IR-2 showed reduction in total chlorophyll content and increased catalase activity as compared to the control one. The susceptible genotypes IR-28, IR-29, Swarna sub-1, NDR-359, Sarjoo52, and IR-64 highly reduced total chlorophyll content and less increased in catalase activity and ultimately lower grain yield per plant as compared to the control plants. The responses observed in tolerant genotypes to salinity stress were higher in catalase activity and less chlorophyll degradation than sensitive genotypes under salt stress.
