Description The experiment was carried out at the Experimental Farm of Department of Seed Science and Technology, Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya, Palampur during kharif, 2012 to rabi, 2013-14 to study the effect of integrated nutrient management on productivity, profitability and seed quality in okra-pea cropping system. Experiment consisted of seven integrated nitrogen treatments in okra viz; 25% nitrogen through FYM + 75% nitrogen through fertilizer; 25% nitrogen through fortified vermicompost + 75% nitrogen through fertilizer; 25% nitrogen through vermicompost + 75% nitrogen through fertilizer; 50% nitrogen through FYM + 50% nitrogen through fertilizer; 50% nitrogen through fortified vermicompost + 50% nitrogen through fertilizer; 50% nitrogen through vermicompost + 50% nitrogen through fertilizer and recommended dose of fertilizer. These seven treatments were tested in randomized block design with 3 replications in okra crop during kharif and three treatments viz; 50% RDF, 75% RDF and 100% RDF constituting 21 treatment combinations, following pea crop in rabi were evaluated in split plot design with 3 replications. Growth, yield attributes, seed yields of okra and pea increased significantly and consistently with combined application of 50% nitrogen through fortified vermicompost + 50% nitrogen through fertilizer as main effects in okra and residual effects in peas. Significantly, higher seed yield of okra (694.4 kg ha-1 and 745.4 kg ha-1) was obtained with the application of 50% nitrogen through fortified vermicompost + 50% nitrogen through fertilizer during both the years (2012 and 2013), respectively. Residual effect of 50% nitrogen applied through fortified vermicompost + 50% nitrogen through fertilizer applied in okra also resulted in significantly higher seed yield of peas (1550 kg ha-1 and 1584 kg ha-1) during both the years of experimentation. N, P, K uptake and available N, P, K was found significantly higher with the application of 50% N through fortified vermicompost + 50% N through fertilizer in both okra and pea crops. Further it was observed that application of 50% nitrogen through fortified vermicompost + 50% nitrogen through fertilizer resulted in significantly higher germination percentage, seedling length, seedling dry weight, field emergence, seedling vigour and lowest electrical conductivity in okra and pea seeds after harvest indicating better seed quality. Among direct effects (fertility levels), 100% RDF also resulted in increased growth, development, yield attributes, seed yield and quality of peas. The okra equivalent yield (1112 kg ha-1 annum-1), net returns (₹ 263853 ha-1 annum-1) and net returns per rupee invested (₹ 3.79) were recorded significantly higher with the application of 50% N through fortified vermicompost + 50% N through fertilizers in okra-pea cropping system.
