The experiment was conducted to evaluate the response of Groundnut to different allowable soil moisture depletion levels. From the three consecutive years of combined data analyses, the effect of different allowable soil moisture depletion level on the yield of groundnut and other yield components was not significantly different. However, there was a statistically significance difference on crop water productivity. Among the five treatments, SMD3, which is had 50% allowable soil moisture depletion level gave the highest mean unshelled yield. Whereas, SMD4, which is had 60% allowable soil moisture depletion level, gave the lowest unshelled yield. 30% allowable soil moisture depletion level gave the highest crop water productivity. Even if the different allowable soil moisture depletion level didn’t did not show a significant difference on yield of Groundnut, 50% allowable soil moisture depletion level gave relatively the highest yield and optimum crop water productivity. Therefore, for Amibara and other similar agroecological areas irrigating Groundnut at 50% allowable soil moisture depletion level will provide an optimum yield. |
