INTERACTION OF DIFFERENT LEVELS OF NITROGEN AND FYM ON YIELD OF DRY DIRECT- SEEDED RICE IN NORTH-WEST, INDIAAnila PradhanAbstract The simultaneous use of synthetic fertilizers and organic manure in combination can help promote sustainable agriculture by improving soil health, reducing environmental impacts, and increasing crop productivity. The research work entitled âInteraction of different levels of organic and inorganic fertilizer on growth and yield of dry-seeded rice (DSR)â was conducted in the field of Lovely Professional University, Phagwara, Punjab during the Kharif season of 2022. The study focused on the influence of various levels of inorganic and organic fertilizers on the growth and yield of DSR. The experiment was laid out in a split plot design with three replications and twelve treatments. The main plots included three rates of farmyard manure (FYM) (0, 7.5, and 15 t ha-1) and subplots with four nitrogen fertilizer rates (0, 50, 100, and 150 kg ha-1). The treatment combinations were: T1: FYM0 N0; T2: FYM0 N50; T3: FYM0 N100; T4: FYM0 N150; T5: FYM7.5 N0; T6: FYM7.5 N50; T7: FYM7.5 N100; T8: FYM7.5 N150, T9: FYM15 N0, T10: FYM15 N50, T11: FYM15 N100, T12: FYM15 N150. The result showed that the application of 150 kg N ha-1 produced the highest yield attributes and grain yield. On the other hand, the highest number of effective tillers, panicle length, number of grains per panicle and 1000 grain weight resulted in the highest grain yield from 15 t FYM ha-1. Simultaneous application of F15N100 gave a significant grain yield in DSR. The interaction between N and FYM was positive and linear. Therefore, the best-combined application of 150 kg N ha-1 and 15 t FYM ha-1 could be the best integrated nutrient management practice for better yield of DSR. |
