### Yield Attributing Characters and Yield  
The yield components and yields of the different cultivars are presented in Table 3. The highest ETH (14.66) was recorded in Binadhan-10, while the lowest (8.33) was observed in Jagliboro. The values of PL forHira-2 (24.78 cm) and BRRI dhan29 (23.65 cm) were the next highest, after Binadhan-10 (25.01). The values of GpP ranged from 89.66 to 125.00. The highest GpP (125.00) was observed in Binadhan-10, followed by Hira-2 (122.66) and BRRI dhan29 (122.00), whereas the lowest (89.66) was noted in Jagliboro. The 1000-grain weight ranged from 17.91 g (Jagliboro) to 26.49 g (Binadhan-10). The GY ranged from 17.28 to 26.26 g pot\({}^{-1}\). Binadhan-10 produced the maximum GY (26.26 g pot\({}^{-1}\)), followed by Hira-2 (25.78 g pot\({}^{-1}\)) and BRRI dhan29 (24.22 g pot\({}^{-1}\)), whereas Jagliboro produced the lowest GY (17.28 g pot\({}^{-1}\)). The SY ranged from 17.72 to 26.57 g pot\({}^{-1}\). The maximum SY (26.57 g pot\({}^{-1}\)) was recorded in Binadhan-10, followed by Hira-2 (26.21 g pot\({}^{-1}\)) and BRRI dhan29 (24.38 g pot\({}^{-1}\)); meanwhile, the lowest (17.72 g pot\({}^{-1}\)) was recorded in Jagliboro. The highest BY (52.83 g pot\({}^{-1}\)) was recorded in Binadhan-10, while the lowest (35.01 g pot\({}^{-1}\)) was found in Jagliboro. Variety had no significant influence on HI. BRRI dhan29 had the maximum HI (49.80 %), while Jagliboro had the lowest (49.36%) HI.
