Abstract:

Irrigation is frequently used to supplement rainfall to increase crop productivity in chickpea. The objective of this study was maximizing chickpea productivity of rainfed agriculture, to determine the effect of supplementary irrigation on chickpea yield, to determine water requirement and to determine water use efficiency. The experiment was conducted in randomized complete block design with three replications. It was consisting of seven levels of irrigation treatment and a control treatment (Rain fed agriculture). Some soil and climatic data were collected and analyzed. The reference evapotranspiration was computed to determine water requirement of chickpea and the seasonal crop water requirement was 288.6mm. Yield components like plant height and pod per plant were analyzed and had significant variations due to application of treatments. The highest value was recorded by applying full amount of supplemental irrigation and the lowest value was at no supplemental irrigation in both parameters. The highest grain yield (890kg/ha) was obtained in fully supplemental irrigation of chickpea and the lowest grain yield (430kg/ha) was obtained no supplemental irrigation. Water use efficiency was analyzed and the highest value was obtained with applied two supplemental irrigation at flowering & fruit setting stages and the lowest was at 1/4 supplemental irrigation.
