| Abstract | ||
| Field experiment was carried out in calcareous loamy sand soil at the Experimental Farm, Faculty of Environmental Agricultural Sciences, Arish University, North Sinai Governorate, Egypt during two successive seasons 2015 and 2016. The objective of this experiment was to evaluate the response of soil water content to water irrigation regimes with and without mulching under surface and subsurface drip irrigation systems. The irrigation system was consisted of 9 irrigation water regime treatments, which were combined with 2 deficit irrigation levels of 25 and 50% from crop evapotranspiration, ETc, were individually subjected throughout the development, flowering and harvesting growth stages and the same deficit irrigation levels were subjected throughout whole growth season as well as the deficit irrigation level of 0% ETc was subjected throughout whole growth season using well water having electric conductivity (ECw) of 7.25 dSm-1and 8.68 SAR. Increasing the deficit irrigation levels significantly decreased volumetric soil water content. Volumetric soil water content with mulching were significantly more than that obtained without mulching. Volumetric soil water content under surface drip irrigation systems were insignificant less than that obtained under subsurface drip irrigation system. | ||
