Investigation of the last irrigation timing for grain corn under Konya basin conditions

Çağlar Yaşar, Ramazan Topak

Abstract


In this study performing at Konya basin conditions, the aim was to determine the last irrigation time for grain maize production. For this purpose, the effects of five different irrigation-ending times [at milking stage (S1); 6 days after S1 (S2); 12 days after S1 (S3); 18 days after S1(S4) ; and 24 days after S1 (S5)] on grain yield were researched under field conditions. By comparison to first irrigation-ending treatment of S1, 80 mm more irrigation water was applied to the latest terminated treatment of S5. The results of the study showed that, effect of different irrigation-ending times on grain yield and gross income was found not statistically significant. However, maximum grain yield and gross income were obtained from S5 treatment.
