Abstract
Field experiments were carried out at El-Bustan Research Station, Nobaria District, Abdel-Monem Reyad Village in order to evaluate the po‌tential of using surface and subsurface drip irrigation (GR. lateral). Lines were installed at two depths of 15 and 30 cm to irrigate squash under the conditions of sandy soil. There were two treatments (daily and three days intervals fertigation). The obtained results showed the superiority of sub-surface drip at depth of 15 cm in case of daily fertigation over surface and sub-surface drip systems installed at 30 cm depth in case of throe days intervals fenigation as follows: 1- The soil moisture distribution as percentage ratio from field ca‌pacity was after irrigation with two hours 95.8 %. 93.8%. 90.8% and be‌fore irrigation with two hours 85.4%. 83.3%,76.5% in case of daily feni‌gation . 2- Under sandy soil conditions, the good water and nutrients management for plant growth could be achieved by using subsurface drip irrigation systems (daily fenigation at depth 15 cm) over other treatments. 3- Crop yield increased in daily fertigation of subsurface drip irri‌gation over the other treatments with ratio 7.55 % to 14.88%. 4- Water use efficiency increased in daily fertigation of subsur‌face drip irrigation over the other treatments with ratio 8.26 % to 15.1%. Keywords: pressurized surface and sub-surface irrigation Fertiga‌lion - Water distribution uniformity — Management - Salt distribution uni‌formity - Crop yield — Water use efficiency.
