Yield and Water Productivity Analysis of Tomato Crop Under Water Stress Conditions in Ethiopia
By irrigating only the first two growth stages of tomato crop, the best water productivity was found without significant yield reduction for a specific growing period (from January 23 to May 22, 2013) under similar local climatic conditions. With this irrigation application, irrigated lands can be increased to 111.4% with the same amount of water. In this study, the rainfall contribution was 41.1% of CWR at mid growing stage and 26% in the later stage. Under such rainfall conditions, irrigating in the mid and/or late growing stages did not show any significant differences in yield.
