TAILIEUCHUNG - Irrigation scheduling of drip-irrigated tomatoes using class a pan evaporation
This study was carried out to investigate the irrigation schedule of drip-irrigated tomatoes (Lycopersicon esculentum cv. Dual Large, F 1) using Class A pan evaporation. Tomatoes plants were grown in a clay soil in the experimental fields of the Research Institute of Rural Services in Eskiflehir between 1998 and 2000. | Turk J Agric For 26 (2002) 171-178 © TÜB‹TAK Irrigation Scheduling of Drip-Irrigated Tomatoes Using Class A Pan Evaporation Öner ÇET‹N Köy Hizmetleri, Araflt›rma Enstitüsü, Su Yönetimi Bölümü, Eskiflehir - TURKEY Osman YILDIRIM Ankara Üniversitesi, Ziraat Fakültesi, Tar›msal Yap›lar ve Sulama Bölümü, Ankara - TURKEY Demet UYGAN, Hasan BOYACI Köy Hizmetleri, Araflt›rma Enstitüsü, Su Yönetimi Bölümü, Eskiflehir - TURKEY Received: Abstract: This study was carried out to investigate the irrigation schedule of drip-irrigated tomatoes (Lycopersicon esculentum cv. Dual Large, F 1) using Class A pan evaporation. Tomatoes plants were grown in a clay soil in the experimental fields of the Research Institute of Rural Services in Eskiflehir between 1998 and 2000. Irrigation water was applied as a certain ratio of Class A pan evaporation (kpc = , , , and ) with different irrigation intervals (2, 4, and 6 days). Significant differences in fruit yields were obtained between the treatments, except for in 1998. Maximum marketable fruit yield was found at the treatment level -1 of of kpc and 4-day irrigation intervals. For this treatment, fruit yield ranged from to t ha depending on the climatological and soil conditions according to the experimental years. Hence, ground variety tomatoes grown in the field under Eskiflehir conditions should be irrigated at 4-day intervals and the irrigation water should be determined using kpc at in combination with cumulative evaporation from a Class A pan. For this program, average irrigation water applied, evapotranspiration, and water use efficiency (WUE) were determined to be 602 mm and 710 mm, and kg m-3, respectively. Key Words: irrigation, scheduling, tomatoes, drip, evaporation.
