Abstract: In order to find suitable varieties of tomato, pepper and cucumber for plastic greenhouse conditions in Ankara and eventually to identify the best N fertilizer rate greenhouse experiments were conducted for two years. Yazgı Fi variety for tomato, Hızır Fi variety for cucumber and Serademre 8 variety for pepper were chosen to be the suitable varieties to grow in the plastic greenhouse conditions in Ankara. Five N treatments [N0 = 0, N1 = 150, N2 = 300, and N3 = 450 kg N/ha; also, soil N application treatment (Nsoil) equivalent to the fertigation treatment of 300 kg N/ha was included for tomato and pepper, however N rates for cucumber was 131, 266 and 339 kg N/ha; Nsoil being 266 kg N/ha.] were investigated using 15N labeled urea ferilizer. Significantly higher marketable fresh fruit and total dry matter yields and N uptakes values were obtained from N3 treatments for tomato and cucumber, but from N2 treatment for pepper. Also, significantly higher yields, N uptakes and % NUE values were obtained when the same amount of N fertilizer is applied through fertigation compared to the treatment where N fertilizer applied to the soil then drip irrigated.
