Abstract

The water-yield relation of eggplant (Solanum melongena L.) was investigated under partial root drying (PRD) technique. In PRD technique, irrigation was applied to one half plant root zone and leaving the other half dry. Relevant measurements and monitoring were carried out regarding the fruit width-height (size), yield, water-use efficiency (WUE), effectiveness of irrigation water-use (IWUE), yield reaction factor (Ky) and etc. The findings of the study suggest that different amount of irrigation water and irrigation water application techniques had effects on yield and yield parameters. The highest yield (83103 kg/ha) and IWUE (194.4 kg/(haxmm)) values were found in the control (FULL). The second highest yield (59483 kg/ha) and IWUE (177.97 kg/(haxmm)) value was found in the APRD75 in which 25% water deficit were applied. The yield and IWUE under the DI50 treatment in which 50% water deficit was applied were found to be, 39886 and 165.60 kg/(haxmm), respectively. The APRD75 and the DI75 techniques may be applied on eggplant under deficit irrigation.
