Effect of Mulching, Cumulative Pan Evaporation Ratio and Nutrient Levels on Yield, Nutrient Content and Uptake of Linseed

Abstract

A field experiment was conducted at Agricultural Research Farm, Institute of Agricultural   Sciences, Banaras Hindu University, Varanasi to find out the effect of mulch, cumulative pan evaporation ratio and nutrient levels on Linseed in alluvial soil of eastern Uttar Pradesh. The experiment was conducted during rabi season 2015-16. On the basis of one year experimentation data showed that mulch consistently recorded significantly higher number of capsules (55.98), number of seeds per capsule (8.15), seed yield (14.62 q/ha), straw (29.62 q/ha) and biological yield (44.23 q/ha). Mulch had also significant effect on N, P, K content and uptake by seed and straw of linseed. Result revealed that Irrigation at IW (Irrigation Water)/ CPE ratio of 100% CPE gave significantly higher number of capsules, number of seeds per capsule, test weight, seed yield, straw yield and biological yield. N, P and K content in seed (3.29, 0.78, 0.71%) and straw (0.73, 0.17, 0.84%) as well as uptake were also significantly higher as compared to IW/CPE of 75% and 50%. 100% Recommended dose of fertilizers had significantly higher number of capsules, number of seeds per capsule, test weight, seed yield, straw yield and biological yield. Application of fertilizer at100%RDF gave significantly higher N P and K content as well as uptake by seed and straw as compare to 75%RDF and no nutrient.
