Abstract/Description: | Longer duration and higher frequency of dry spells in monsoon season is one of the major causes of low productivity and failure of rice crops in India, Keeping this in view, a field experiment was conducted to study the response of kharif rice to supplemental irrigation under drip and surface irrigation methods in a sub-humid tropical climate of eastern India. Water was applied to rice after three days of drainage of standing water in field. Different drip irrigation (DI) treatments imposed were irrigation at 125% crop evapo-transpiration (ETc), 100% ETc and 75% ETc, at 1.0 m lateral layout (lateral-to-lateral distances) whereas surface irrigation (SI) was applied through flexible hose-pipe to rice plots. Rain-fed rice was taken as control treatment for comparison. The irrigation water applied under different DI treatments varied from 108 mm to 179 mm whereas it was 250 mm under SI. The highest vegetative growth of rice was recorded under DI at 125% ETc, whereas higher grain yield was harvested from SI which was statistically at par with that under DI at 100% ETc and 125% ETc. However, the maximum irrigation water use efficiency was obtained from DI at 100% ETc. The grain yield of drip-irrigated rice was 26% higher than rain-fed rice. The effect of irrigation on available nutrients (N, P and K) in soil was statically (p>0.05) insignificant. |
