An experiment was conducted in a clay soil in the fields of a research institute in Eskisehir, Turkey between 1998 and 2000 to investigate the irrigation schedule of drip-irrigated tomatoes (cv. Dual Large F 1) using Class A pan evaporation. Irrigation water was applied as a certain ratio of Class A pan evaporation (kpc= 0.50, 0.75, 1.00 and 1.25) with different irrigation intervals (2, 4, and 6 days). Significant differences in fruit yields were obtained between the treatments except those of 1998. Maximum marketable fruit yield which ranged from 116.6 to 176.3 tonnes/ha was found at 1.00 kpc and 4-day interval. The average irrigation water applied, evapotranspiration, and water use efficiency was 602 mm, 710 mm and 23.8 kg/m3, respectively. Results indicated that ground variety tomatoes grown in the field under Eskisehir conditions should be irrigated every 4 days and the quantity of irrigation water should be 1.00 kpc from Class A pan.
