Abstract :The experiment was conducted in the farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to study the effect of various organic manures and inorganic fertilizers with different water management on the nutrient availability of boro rice field. BRRI dhan29 was used as the test crop in this experiment. The experiment consists of 2 factors i.e. Irrigation and fertilizer plus manure. Two levels of irrigations insert ignore into journalissuearticles values(I 1 = Continuous flooding and I 2 = Saturated Condition); were used with 8 levels of fertilizer plus manure, as T 0 : Control, T 1 : 100% insert ignore into journalissuearticles values( N 120 P 25 K 60 S 20 Zn 2 ); Recommended dose of Fertilizer, T 2 : 50% NPKSZn + 5 ton cow-dung ha -1 , T 3 : 70% NPKSZn + 3 ton cow-dung ha -1 , T 4 : 50% NPKSZn + 5 ton compost ha -1 , T 5 : 70% NPKSZn+3 ton compost ha -1 , T 6 : 50% NPKSZn + 3.5 ton poultry manure ha -1 and T 7 : 70% NPKSZn+2.1 ton poultry manure ha -1 , with 16 treatment combinations and 3 replications. The pore-water samples were collected and analyzed during rice growing period. The higher concentrations of N, P and K were found in the pore water of T 6 insert ignore into journalissuearticles values(50% NPKSZn + 3.5 ton poultry manure ha -1 ); and T 7 insert ignore into journalissuearticles values(70% NPKSZn + 2.1 ton poultry manure ha -1 ); treatments where higher yield were obtained. The higher N, P, K & S concentrations and uptake were observed in the treatments where fertilizer plus manure were applied. The highest concentrations of grain N insert ignore into journalissuearticles values(1.31%);, P insert ignore into journalissuearticles values(0.272%);, K insert ignore into journalissuearticles values(0.195%); and S insert ignore into journalissuearticles values(0.091%); were recorded from T 5 , T 3 , T 7 and T 2 treatment respectively and lowest from T 0 insert ignore into journalissuearticles values(Control); treatment.Keywords : Boro rice field, Effect of fertilizer, manure, irrigation, nutrient availability in soil
