To asses variability in rice productivity and nutrients concentrations along with their uptake in relation to soil supply capacity of plant nutrients and their management for developing fertilizers prescription alone and in conjunction with optimum dose of farm yard manure (FYM) under various emerging rice production systems to achieve maximum rice production with good quality and improving different physico-chemical characteristics of experimental soils Taking this fact in view present investigation was planned and conducted during five consecutive kharif seasons 2014 to 2018 to evaluate the impact of various treatments on the rice ‘NDR-359’ Results obtained from the experiment revealed that average maximum grain (61.18 q ha-1) and straw yield (71.30 q ha-1) panicles m-2 (378), Filled grains (195), Plants height (116.5 cm) panicle length (29.10 cm) along with net return (Rs 33343.10 ha-1) and BCR (2.15 Rs-1) were recoreded in transplanted rice fallowed by DSR crop establishment method. The aforesaid yield and yield components of rice ‘NDR-359’ were obtained lowest in aerobic rice establishment method. Grain yield of rice under transplanted establishment method (TPR) showed 15.65 % and 22.71% more than D.S.R and A.R. establishment methods, respectively. However, direct sown rice method recorded its superiority (5.59%) over aerobic rice. Amongst nutrient management addition of 100% RDF. + 50% N through FYM noticed significantly highest grain and straw yield along with various yield components, net returns (Rs 32482) with 2.18 BCR value (T4) followed by T1, T2 and T5. Lowest yield and yield attributing characteristics with net profit were observed in that plot which received 100% RDF through FYM alone. Maximum average nitrogen, phosphorus and potassium uptake by grain was 83.74, 21.75, and 28.31 kg ha-1 and by rice straw was 61.3, 10.85 and 99.29 kg ha-1, respectively in that plot which treated with 100 % RDF along with 50 % N through FYM and lowest N (64.47 kgha-1), P (16.54 Kgha-1) and K (21.98 kgha-1) uptake rice grain in that condition where 100 % RDF was added through FYM alone. Integrated use of fertilizer nutrients on the basis of recommendation along with optimum level of FYM or V.C. significantly enhanced N, P and K use efficiency percentage over 100 % NPK through FYM alone. The different quality characteristics of rice grain and availability of NPK and organic carbon content after termination of experiment markedly improved under all crop establishment methods and nutrient management practices. Maximum organic carbon content in experimental soil was determined in TPR (46%) followed by DSR (33%) and A.R. (29%) under crop established matters and 27% (100% NPK through FYM) and 15% more than that of initial soil under nutrient management practices.
