| Abstract | ||||
| Field experiment was carried out at the Experimental Farm, Faculty of Environmental Agricultural Sciences, Arish University, El-Arish, North Sinai Governorate, during two successive seasons, 2014/2015 and 2015/2016. The experiment was investigated to study the response of tomato fruit yield, tomato actual evapotranspiration, water use efficiency, the crop water productivity, water production function and crop response factor to water irrigation regimes with and without mulching under surface and subsurface drip irrigation systems. Each irrigation system consisted of 9 treatments with the addition irrigation water as crop evapotranspiration percentage (ETc%) were subjected throughout the whole growth season or individually subjected throughout various growth stages. Increasing the deficit irrigation levels, significantly decreased tomato fruit yield, total tomato actual evapotranspiration, water use efficiency. Total tomato actual evapotranspiration values with mulching by black plastic sheet were significant less than those values obtained under without mulching, while tomato fruit yield and water use efficiency values(WUE) with mulching were significantly more than those obtained without mulching. | ||||
