| Publisher Description: The experiment was conducted to see the effect of spacing and poultry manure (PM) based integrated plant nutrient management in SRI method on the growth and yield of transplant aman rice. The experiment included three spacings viz. 25cm×15cm (conventional spacing), 30cm×30cm and 40cm×40cm, and seven PM based integrated fertilizer (NPKSZn) management viz. control i.e. without fertilizer, 100% NPKSZn i.e. recommended dose of fertilizer by BRRI [80, 26, 33, 11 and 2 kg/ha of N, P, K, S and Zn, respectively], 5 t/ha of PM, 50% NPKSZn+5 t/ha of PM, 50% NPKSZn+2.5 t/ha of PM, 75% NPKSZn+5 t/ha of PM and 75% NPKSZn+2.5 t/ha of PM were used. From this study it is found that both conventional spacing with 50% NPKSZn and 5 t/ha PM, and conventional spacing with BRRI recommended dose of fertilizer gives the highest grain yield. Based on the results obtained the best combination for the cultivation of BRRI dhan41 under SRI method during aman season was to use the conventional spacing×50% NPKSZn with 5 t/ha of PM to obtain the highest grain yield. Because it not only reduced the production cost but also had a long term impact on improvement of soil properties. |
