  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.

  The study was conducted to investigated the effect of irrigation and irrigation on growth and yield of wheat (cv. Kanchan). The results revealed that both the irrigation and nitrogen gave significant (p<0.05) effect on all studied growth parameters such as plant height (90.09 and 90.42 cm), number of tillers plant-1 (3.21 and 3.20), leaf area index (LAI) (1.37, 1.55 at 60 DAS and 3.73, 4.77 at 75 DAS), crop growth rate (CGR) (282.10, 333.13 mg day-1 plant-1 at 60-75 DAS and 158.99, 177.35 mg day-1 plant-1 at 75-90 DAS) and relative growth rate (RGR) (0.108, 0.1098 mg mg-1 day-1 at 60-75 DAS and 0.021, 0.022 mg mg-1 day-1 at 75-90 DAS). Among the yield contributing characters the number of effective tillers plant 1 (2.89 and 2.92), number of non effective tillers plant-1 (0.52 and 0.67), number of non-fertile spikelets spike-1 (2.44 and 2.51), grain yield (2.69 and 2.50 t ha-1) and harvest index (46.55 and 45.25%) were significantly influenced by irrigation as well as nitrogen level. The increments of grain yield mainly due to increase in number of effective tillers plant-1.
