The experiment was conducted in Randomized Complete Block Design with four replications and six treatment combinations. Results showed that, application of RDF + FYM was found superior in terms of seed yield (2,430 kg ha-1) and stalk yield (4,531 kg ha-1) which was on par with 50 % RDF + 50 % organics through FYM + vermicompost. The highest total NPKS uptake (258.5, 42.95, 170.17 and 44.42 kg ha-1 respectively) and micronutrients like Zn, Fe, Cu and Mn uptake (348.7, 1444.4, 134.7 and 324.6 g ha-1 respectively) were recorded with application of RDF + FYM which was on par with 50 % RDF + 50 % organics through FYM + vermicompost. The highest available N, P2O5, K2O, S and micronutrients were recorded with application of 50 % RDF + 50 % organics through FYM + vermicompost. Further, quality parameters like oil content (20.70 %) and protein content (42.13 %) and highest B:C ratio (3.10) were realized in the same treatment. The improvement in soil physical properties particularly maximum water holding capacity, infiltration rate, aggregate stability and organic carbon content and biological properties like dehydrogenase activity (36.27 μg TPF g soil-1 per day-1) were significantly higher with the application of 100 % organics through FYM, GLM and vermicompost followed by 50 % RDF + 50 % organics through FYM + vermicompost.EnglishThesis
