Abstract: In order to study the effect of planting methods and integrated nutrient management in rice. A field experiments was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (Utter Pradesh) during Kharif 2014. The experiment was laid out in split plot design with four replications. The treatment consisted of four planting methods (S1- transplanting, S2-SRI, S3- drum seeded and S4- direct seeded) and three integrated nutrient management (F1- 100% NPK, F2- 75% NPK+25% FYM and F3- 50% NPK+ 50% FYM) in this way there were 12 treatment combinations. The values of growth contributing characters viz. plant height (cm), number of tillers m-2, dry matter accumulation (g m-2), leaf area index, and yield attributes like number of panicles m-2, length of panicle (cm), number of panicle-1, grain weight panicle-1, test weight (g), grain and straw yield (q ha-1) and nutrient uptake of rice were increasing significantly with SRI method (S2) followed by transplanting method (S1) and significantly superior over rest of the treatments. In case of integrated nutrient management the growth characters like plant height (cm), number of tillers m-2, dry matter accumulation (g), LAI, yield attributes’ number of panicle m-2, length of panicle, grain weight panicle-1,test weight (g), nutrient uptake, grain and straw yield (q ha-1) of rice were maximum under F2 (75% NPK+25% FYM) which was at par with F1 100% NPK during course of investigation. The maximum gross return and net return were noted under SRI with 75% NPK+25% FYM (S2F2) application. The highest benefit cost ratio (2.47) were recorded with SRI method with 100% NPK treatment (S2F1) followed by SRI with 75%NPK+25% FYM (S2F2) they proved more remunerative then other treatment combinations.
