Abstract:
This study was carried out to determine the most suitable irrigation scheduling and crop coefficient for fresh market tomatoes (Ringo – F1) and eggplants (F-1Roma) grown on a silty clay soil in unheated greenhouses condition at the Directorate of Agriculture research at Bakrajow site situated to the southwest of Sulaimani during the 2011seseon. The yield response of tomatoes and eggplants to drip irrigation were investigated. Three different irrigation levels (WL-100, WL-75 and WL- 50% of available water) the highest yield was obtained from the (WL-100%) treatment. Tomatoes’ and eggplants yields decreased with available water. The highest water use efficiency (WUE) value for tomatoes and eggplants were obtained from WL- 50% of available water were (11.41kg /m2), (9.1841kg /m2) respectively. WUE increased in all treatments as the amount of irrigation water decreased. The crop coefficient (kc) of tomatoes and eggplants were obtained from (WL-100%, WL-75% and WL-50% of available water) were (1.38, 0.92and 0.68), (2.02, 1.27and 0.88) respectively. And the highest crop coefficient (kc) of tomatoes and eggplants (1.38), (2.02) were obtained from (WL-100% of available water.
