A field experiment was conducted to investigate the effect of four different number of seedling hill -1 viz., 2, 3, 4 and 5 and five different culm cutting height viz., 5, 10, 15, 20 cm and no cutting (control) on rice green fodder, hay and seed yield of transplant aman rice cv. Binadhan 4. Results revealed that the green fodder yield increased with the decreasing cutting height. The highest (4.55 t ha -1) and the lowest (2.75 t ha -1) green fodder yields were obtained from cutting at 5 and 20 cm, respectively. Identically the highest green fodder yields (3.03 and 2.99 t ha -1) were found by 5 and 4 seedling hill-1 treatments. The highest hay yield was obtained from 20 cm cutting height and 5 seedling hill -1. Plant height was positively related to cutting height, the highest (141.38 cm) and the lowest (117.67 cm) plant height at harvest were due to control and cutting at 5 cm treatments, respectively. Seed yield decreased with the decreasing cutting height. The highest and the lowest seed yields were obtained from control and cutting at 5 cm, respectively. The highest seed yield was found in 3 seedling hill -1.
