Abstract:

An experiment was done at a farmer’s field in Barishal district to evaluate the comparative performance of one hybrid rice variety- Sorno balam, with four modern varictics BR 11, BRRI dhan 52, BRRI dhan75 and BRRI dhan 87 in Transplanted aman season of 2021. Hybrids and conventional rice varieties differed significantly among themselves to different parameters under study. The highest grain yield (6.40 t/ha) was recorded from the hybrid Sorno balam followed by BRRIdhan87 (5.23 t/ha) and the lowest in BRRI dhan 75 (4.20 t/ha). Further, hybrid Sorno balam produced the highest straw yield (8.7 t/ha), which varied significantly with all other varieties. Minimum days to first flowering 80.67 and maturity (114.33) were noticed in BRRIdhan75 followed by Sorno balam (115.67 and 153.33), respectively. The hybrid variety had a heavier grain weight (26.50 g) than the conventional varieties (21-25 g). It is noted that the hybrid variety maintained a distinct statistical edge over the conventional varieties regarding most of the parameters. Thus, the hybrid Sorno balam was found to be superior to modern varieties for transplanting in the aman season in the Barishal district of Bangladesh.
