Studies on the effect of integrated nutrient management practices (INM) on yield and economics of aromatic rice (Oryza sativa L.)

A field experiment was conducted at Instructional farm, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya during kharif season 2018 to evaluate the effect of effect of integrated nutrient management (INM) on yield, and economics of aromatic rice (Oryza sativa L.) var. Basmati. The treatments consisted of different sources of organic manures and inorganic fertilizer viz., T1 (100:40:30 kg ha-1 N2, P2O5, K2O) kg ha-1, T2 (75% NPK + 25% N through vermicompost),T3 (75% NPK + 25% N through FYM), T4 (50%NPK+25%N through vermicompost FYM), T5 (50% NPK + 50% N through FYM), T6 (50% NPK + 50% N through vermicompost), T7 (125% NPK (RDF) T8 (100% NPK + 25% N through FYM) T9 (100% NPK + 25% vermicompost).among all the treatments, application of 100% NPK+25% vermicompost (T9) registered taller plant, no. tillers-2, Number of Panicle m-2, grain per panicle and Length of panicle (cm), protein content, kernel length, kernel breadth, hulling %, milling %, Grain yield and straw yield followed by treatment having T8 (100%NPK +25% N through FYM). Maximum net return (Rs.) and benefit cost ratio recorded in the treatment having 100% NPK+25% vermicompost (T9).
