Yield Performance of Transplant Aman Rice Influenced by Organic and Inorganic Sources of Fertilizers

Abstract

Abstract
Poultry manure contains significant amount of essential plant nutrients. An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh during July–December 2011 to observe the effect of poultry manure and inorganic fertilizer on two varieties viz. (i) BR11 and, (ii) BRRI dhan52 of transplant aman rice. The fertilizer treatments were (i) control (no poultry manure and inorganic fertilizers) (MO), (ii) poultry manure @ 5 t ha-1(M1), (iii) recommended dose of inorganic fertilizers (i.e., 80, 60, 40, 60,10 kg N, P205, K20, gypsum and ZnSO4 ha-1, respectively) (M2), (iv) 50% NPKSZn + poultry manure @ 2.5 t ha-1 (M3), (v) 50% NPKSZn + poultry manure @ 5 t ha-1 (M4), (vi) 75% NPKSZn + poultry manure @ 2.5 t ha-1 (M5), (vii) 75% NPKSZn + poultry manure @ 5 t ha-1 (M6). The experiment was laid out in a randomized complete block design with three replications. Varieties had significant influence on almost all the parameters. Poultry manure and inorganic fertilizer (NPKSZn) combinations showed significant effect on all plant characters and yield components except plant height and 1000-grain weight. Effect of interaction between variety and poultry manure and inorganic fertilizer (NPKSZn) combinations was significant on all plant characters and yield components except 1000-grain weight and straw yield. The performance of BRRI dhan52 was better regarding grains panicle-1 (137.65), grain yield (4.62 t ha-1), 1000-grain weight (25.99 g) and harvest index (46.03%) than that of BR11. 50% NPKSZn manure @ 2.5 t ha-1 + poultry performed the best in respect of yield and yield components.
