Integrated nutrient management of mustard (Brassica juncea L.) alluvial soil of Uttar Pradesh

A field experiment was carried out in the pot culture of Soil Science and Agricultural Chemistry, C S Azad University of Agriculture & Technology during 2017-18. The experiment consisted 9 treatments viz. T1: Control, T2: 100% N (RDF), T3: 75% NPK (RDF), T4: 75% NPK + FYM T5: 75% NPK + FYM + PSB + S, T6: 100% NPK, T7: 100% NPK + FYM, T8: 100% NPK + PSB + FYM and T9: 100% NPK + FYM + PSB + S assigned in randomized block design replicated thrice during rabi season of 2017-18. The soil of the experimental plot was sandy loam in texture, medium in fertility and slightly alkaline in reaction. The weather during the experimental period was by and large normal and devoid of any extreme conditions. The results indicated that application of T9: 100% NPK + FYM + PSB + S resulted in significantly maximum plant height, number of functional leaves, number of branches plant-1, girth of plant, days to 50% flowering and maturity, root development, Oil (%), Oil yield and ultimately higher seed yield and straw yield as compared to other corresponding tested treatments. The treatment also excelled in harvest index, net return and benefit: cost ratio under control.
