Grain, Yield and Quality of Transplant Aman Rice and Soil Nutrients Status with Application of Fertilizers and Green Manures

A field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka during 2014 on transplant aman rice var. BR11 (Mukta) under different levels of chemical fertilizers and green manures to evaluate its grain yield, quality soil fertility status with incorporation manures. The carried out in a split- plot design three replications. level (0, 100, 75, 50% recommended dose, RFD) placed main -plot management 5 10 t ha-1 each Mimosa invisa (Lajjaboti) Sesbania spp. (Dhaincha) sub-plot. Recommended dose 83N, 21P, 37K, 11S 1.5 Zn kg ha-1, were applied the form urea, triple super phosphate (TSP), muriate potash (MoP), gypsum zinc sulfate, respectively. Sixty-day old - vitro incorporated before transplantation. Combined application 75% RFD along @ proved be best producing higher yield (7.25 ha-1) that par treatment plus ha-1. Quality increased markedly respect amylose, carbohydrate, protein as well. Furthermore, improved nutrient organic matter, nitrogen, sulfur over no incorporations So, addition manure like could cut fertilizer cost by 25-50%.
