Investigation of the Last Irrigation Timing for Grain Corn under Konya Basin Conditions

Özet

In this study performing at Konya basin conditions, the aim was to determinethe last irrigation time for grain maize production. For this purpose, the effectsof 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 firstirrigation-ending treatment of S1, 80 mm more irrigation water was applied tothe latest terminated treatment of S5. The results of the study showed that,effect of different irrigation-ending times on grain yield and gross income wasfound not statistically significant. However, maximum grain yield and grossincome were obtained from S5 treatment.
