This study was conducted to evaluate the effect of different water depths on the growth and yield of rice crop. Experiment was carried out in containers having an area of 0.64 m2 and the volume of 0.57 m3 at laboratory. Four water depths of 5, 10, 15 and 20 cm were taken in account; each water depth was replicated three times. This study was conducted in controlled condition to avoid the impact of rain. Result indicated that 5 cm is optimum water depth for vegetative and mid stage (transplanting to mid drainage) of the rice crop growth, while 10 cm water depth is appropriate for mid drainage till late stage (mid drainage to harvesting) of the rice crop and the same (10 cm) is found suitable for maximum yield.
