| Abstract | ||
| Fine rice varieties are sensitive to nutrient management, which plays a crucial role in optimizing their yield and quality. This study aimed to evaluate the performance of selected fine rice varieties under different nutrient management practices. The experiment comprised four rice varieties viz Kalizira, Binadhan-13, BRRI dhan34 and BRRI dhan38 and five nutrient management viz. Control, recommended dose of urea (RDU) (150 kg N/ha), 50 % RDU, 50 % RDU + poultry manure (PM) 5 t/ha, 50 % RDU + PM 2.5 t/ha. The maximum grain yield (3.79 t/ha) was produced in BRRI dhan34 followed by Binadhan-13 and the lower one (3.05 t /ha) in BRRI dhan38. Integrated use of 50% RDU + PM 5 t/ha impacted significantly on morphological characteristics and yield-contributing traits of aromatic rice yield. Yield traits, such as effective tillers/hill, grains/panicle, and 1000-grain weight, exhibited the highest values when 50% of the RDU + PM 5 t/ha was applied whereas the control group had the lowest values. BRRI dhan34 fertilized with 50% RDU + PM 5 t/ha produced higher yield (3.79 t/ha) compared to other combinations. It can be concluded that at 50 % RDU + PM 5 t/ha can be used for the best performance in terms of grain yield of fine rice (cv. BRRI dhan34). | ||
