Effect of irrigation and fertilizer, manure on the yield of boro rice
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 growth and yield of Boro rice. BRRI dhan29 was used as the test crop in the experiment. The experiment consists of 2 factors (i) Irrigation and (ii) fertilizer plus manure. Two levels of irrigations (I1= Continuous flooding and I2= Saturated Condition) were used with 8 levels of fertilizer plus manure, as T0: Control, T1: 100% ( N120P25K60S20Zn2) Recommended dose of Fertilizer, T2: 50% NPKSZn + 5 ton cow-dung ha-1, T3: 70% NPKSZn + 3 ton cow-dung ha-1, T4: 50% NPKSZn + 5 ton compost ha-1, T5: 70% NPKSZn + 3 ton compost ha-1, T6: 50% NPKSZn + 3.5 ton poultry manure ha-1 and T7: 70% NPKSZn + 2.1 ton poultry manure ha-1, with 16 treatment combinations and 3 replications. The yield parameters and yields were significantly affected by fertilizer and manure. The highest grain yield (7.40 ton/ha) was found from T7 (70% NPKSZn + 2.1 ton poultry manure ha-1) treatment which was closely similar to T6 (50% NPKSZn + 3.5 ton poultry manure ha-1) treatment and lowest yield was obtained from T0 treatment. The higher grain yields were found by the application of organic plus inorganic fertilizers compared to the use of chemical fertilizer alone. The yield parameters were not significantly influenced by combined application of irrigation and fertilizer and the highest grain yields (7.51 ton/ha) were recorded from I1T1 (Continuous flooding + 100% (Recommended dose of Fertilizer) which was closely similar with the yield of I1T7 (Continuous flooding + 70% NPKSZn + 2.1 ton poultry manure ha-1) and lowest (3.69 ton/ha) from I2T0 (Saturated Condition + control treatment) treatment combination.
