A field experiment was conducted during kharif season 2013 to estimate the correlations and path coefficients for ten quantitative characters among 72 cowpea germplasm. Seed yield per plant had positive significant correlation with days to 50% flowering, plant height, primary branches per plant, pods per plant, pod length, seeds per pod and 100-seed weight at both genotypic and phenotypic levels. Path coefficient analysis revealed that primary branches per plant and 100-seed weight had high direct positive effect on seed yield per plant at both genotypic and phenotypic levels. Pod length, days to maturity, 100 seed weight and pod wall proportion had high positive direct effects on seed yield per plant at only genotypic level. Correlation and path analysis indicated that for increasing seed yield in cowpea direct selection should be carried out for higher values of primary branches per plant, pods length, days to maturity and 100 seed weight.

An analysis has been carried out to explore the genetic variation in seventeen selected varieties of fenugreek. Sixteen fatty acids were identified in seed oil. Linoleic acid (18:2; n-6) and -Linolenic acid (18:3; n-3) were the major contributor found in the range of 26-43% in variety Lam Selection. The MUFA content varied from 3.50% in Azad Methi to 19.31 % in Hisar Madhvi. The ratio of n-6 to n-3 fatty acids indicated that fenugreek seed lipids are a good source of PUFA. PCA identified linolenic and oleic acid as the most important traits responsible for variation in presented material and improving quality through breeding. Estimates of genetic distance values showed wide range of variation among the fenugreek genotypes. The Euclidean based UPGMA clustering revealed three real and four singleton clusters. Genetic diversity showed no relationship to geographical origin. Dissimilarities obtained showed a wide variation in oil content and in composition.

Field experiment was undertaken at research farm of IARI, New Delhi to study the effect of change in the microenvironment under different colour shade nets during summer and rainy season, of 2012 on yield of spinach. Spinach crop was sown under different colour shade nets such as red, green, black, white along with control (without shade net) during summer and rainy season. Crop duration from sowing to harvesting was 62 days in summer and 58 days in rainy season. Different weather parameters were measured at regular interval in each treatment. Results showed that the light intensity, incoming radiation, canopy temperature, air temperature, soil temperature were found to be lower under different colour shade nets compared to the control. However the relative humidity, soil moisture were found to be higher under colour shade nets compared to control.
