Effect of Partial Root Drying and Deficit Irrigation on Yield and Water Use Efficiency of Tomato Grown Under Greenhouse

Water conservation strategies are becoming increasingly important as a result of the shortage water and climate change. The purpose this study is to address water-saving irrigation by evaluating effect partial root drying (PRD) Deficit Irrigation (DI) practice on yield use efficiency tomatoes (Shivam variety). treatments were at 75% 50% crop evapotranspiration, ETc (PRD25 PRD50, respectively), deficit (DI25 DI50, respectively). PRD requires wetting one half zone keeping other dry, consequently using less amount that was applied. In successive irrigations, wet dry sides alternated. Over growing season after transplanting, highest fruit obtained under FULL (225 t ha-1). comparison received same quantity water, produced an increased 5–10%. DI improved WUE considerably, 30.35% 25.71% respectively higher than FI. Results suggest treatment may be option in shortage.
