Effect of Planting Techniques With Organic and Inorganic Nutrient Management for Improving Crop, Water Productivity, Profitability and Soil Health in Rice (Oryza Sativa L.) Under Rice-wheat Cropping System

Abstract

The present investigation “Effect of planting techniques, with organic and inorganic nutrient management for improving crop, water productivity, profitability and soil health in rice (Oryza sativa L.) under rice-wheat cropping system” was conducted during the kharif season (2019) at Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.). Experiment was conducted to assess different Planting Techniques, Fertility levels on Crop & Water Productivity, Profitability. It was laid out in split plot design with three replications. The main factor consisted of four planting techniques viz. (M1-Reduced Tillage- Transplanted Rice (RT-TPR), M2-Conventional Tillage- Transplanted Rice (CT-TPR), M3-Furrow Irrigated Raised Beds (FIRB), M4-Unpuddled-Transplanted Rice (UP-TPR)) and sub factor six fertility levels viz (S1-Control, S2-100% NPK Chemical fertilizer, S3-100% N (FYM), S4-50% NPK + 50% N (FYM), S5-75% NPK + 25% N (FYM), S6-100% NPK + 25% N(FYM)) as subplot treatment. The soil of experimental site was low in organic carbon and nitrogen and medium in available phosphorus and available potassium and alkaline in reaction. The maximum values of growth characters and yield attributes (plant height, number of tillers, dry matter accumulation, number of effective tillers, grains/panicle and test weight) was recorded in M2 (CT-TPR) treatment which remained at par with M4 (UP-TPR) treatment. Similarly, maximum grains & straw yield, nitrogen, phosphorus and potassium uptake and net return was noticed in this treatment. Among fertility levels treatments, the maximum values of growth characters (plant height, number of tiller and dry matter), yield attributes (number of effective tillers, grain/panicle and test weight), grain and straw yield, nutrient uptake and net return were noticed with application of S6-100% NPK + 25% N(FYM)). Thus, However, these results are only indicative and require further experimentation to arrive at more consistent and final conclusion that planting of rice crop with combination of CT-TPR planting technique & 100% NPK + 25% N(FYM)) for achieving higher yield, net return and improving soil health.
