Abstract

This investigation aims to study the response of King Ruby seedless grapes to suburface drip irrigation system in old valley. The field experiments were carried out during the two seasons, of 1996 and 1997. in "Gharbia Governorate'.Soil moisture, salinity distribution, weeds growth and crop yield (quantity and quality), were measured. Water use efficiency by grapes was also considered, In a comparison between subsurface drip irrigation system and surface drip irrigation system, the results showed that highest yield and best quality of grapes were obtained when irrigated the grapes by using suburface drip irrigation system.
