The investigation entitled “Evaluation of planting systems and integrated nutrient management productivity nutrient uptake and economics of wet season rice (Oryza sativa L.)” were carried out at the Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, U.P. during kharif seasons of 2017. The experiment consisting three crop establishment practices in main plots viz; P1 conventional puddled transplanted rice (CT- TPR), P2 wide raised beds transplanted rice (WB TPR) and P3 reduced till transplanted rice (RT-TPR) and ten fertility levels in sub-plots viz; F1 control, (no fertilizer), F2 RD (150-60-40 kg N-P-K/ha), F3 75% RDF + FYM 5 t/ha, F4 75% RDF +FYM 5t/ha + Zn, F5 75% RDF + FYM 5t/ha+ BF, F6 75%RDF + FYM 5t/ha+ BF + Zn, F7 100% RDF + FYM 5t/ha, F8 100%RDF + FYM 5t/ha + Zn, F9 100%RDF + FYM 5t/ha+ BF and F10 100%RDF + FYM 5t/ha+ BF + Zn was laid out in split -split plot design with three replications.
The plant height, tillers m-2 dry matter accumulation increased with transplanted basmati rice on wide raised beds and transplanted basmati rice after puddling. Among the yield attributes number of grains per panicle, panicle length (cm), and test weight were increased in transplanted basmati rice on wide raised beds and transplanted basmati rice after puddling plots, respectively. The improvement in grain yield 8.9 and 8.4 per cent under transplanted basmati rice after puddling and transplanted basmati rice on wide raised beds plots, respectively over transplanted basmati rice after reduced tillage practices. The infiltration rate was 52.8% higher under transplanted rice on wide raised beds over conventional method. The highest net profit and B: C ratio was recorded in P2. Results also indicated that rice transplanted on wide raised beds and transplanted rice under reduced tillage plots consumed more moisture from the deeper profile layer than conventional tillage practice. Transplanted basmati rice after puddling recorded higher bulk density and more contribution from top layer. Mean weight diameter recorded significantly lower under conventional technique as compared to FIRB planting. Plant height, dry matter accumulation and number of tillers were higher in F10. The yield productive tillers, grains panicle-1, grain panicle-1 and test weight increased significantly (7.4%, 12.2%, 2.4% and 25.5%) in F10 (RDF + FYM +BF +Zn) plots, respectively. The grain yield increased 17.8% in F10 than rest of the treatments. Nitrogen, phosphorus and potassium content were higher in fertility levels of F10 and F9.
