Abstract
A field experiment was conducted to evaluate the effect of different nitrogen levels on the performance of four rice varieties in transplanted aman (monsoon) season. Aromatic rice varieties included BRRI dhan 38, Kalizira, Badshabhog and Tulsimala, while nitrogen was applied at 30, 60, 90 and 120 kg ha -1 . Performance of different varieties was different. All the yield contributing characters differed significantly due to variety. Kalizira produced the maximum number of grains per panicle (135.90). Among the varieties, BRRI dhan 38 gave the maximum grain yield (4.00 t ha -1 ). Different nitrogen rates also significantly affected the aromatic rice varieties. All the yield components were significantly increased up to 90 kg N ha -1 . Nonetheless, maximum grain yield (3.62 t ha -1 ) was observed from 60 kg N ha -1 . The combination of varieties and nitrogen rates also affected the plant characters and yield components of aromatic rice, which ultimately affected the yield and it was observed that in combination the variety BRRI dhan 38 was more responsive to nitrogen to produce better yield.
