ABSTRACT: The trials were carried out during 2015 and 2016 seasons on Flame Seedless grapevines grown in sandy soil under drip irrigation systems at Al-Khatatiba district, in El-Monoufia Governorate, Egypt. The aim of this research was to save irrigation water without any reduction of growth, productivity and quality of Flame Seedless grapevines. In this experiment irrigation systems were applied as follow; subsurface drip, surface drip and suspended drip irrigation named as (SD, D, PD respectively). Beside three level of irrigation (60, 80 and 100% of calculated applied water) named as (W1, W2 and W3). The obtained results cleared that: The most high uniform distribution of soil moisture contents is under PD, the highest soil moisture contents values are under (SD,W3), SD irrigation system underW2 water amount resulted the best number of leaves per shoot, leaf area, total chlorophyll content.......
Keywords: grapevine, drip, suspended drip, subsurface drip, water, sand.
