استجابة محصول الباذنجان لطريقة الري بالتنقيط تحت السطحي بالمقارنة مع الري بالتنقيط السطحي والمروز تحت ظروف الزراعة التقليدية

In order to study and assess the use of subsurface drip irrigation (SDI), Surface Drip Irrigation (SD) and Furrow Irrigation (FI) methods and their effect on growth and yield components of Eggplant, field experiment was designed with three main treatments representing the irrigation methods and the different irrigation intervals ( 1, 3 and 5 day ) with irrigation water quantity of 1.72, 1.28 and 1.06 m3/m2 respectively. Those treatments were applied in a factorial experiment according to randomized complete block design with three replications. Growth parameters and yield data were collected during the experimental period. Based on the results of this work, application of SDI caused better condition for Eggplant growth parameters, in comparison with surface drip irrigation (DI) and FI methods. Furthermore, application of SDI produced highest yield and, therefore, highest water-use efficiency in comparison with the other two methods - DI, furrow irrigation. The saving percentages in quantity of irrigation water used at 5 days interval, for SDI method about 21% and 62% compared with irrigation at 3 and 1 day interval, respectively.
