Yield characteristics of sweet corn under deficit irrigation in Southeastern Turkey

Issue Date

Abstract

The influence of deficit drip irrigation on yield characteristics of sweet corn was determined in Sanliurfa, Turkey during the 1998 and 1999 cropping seasons. Water was applied to sweet corn as 100%, 90%, 80% and 70% of evaporation from a Class A Pan (E pan). Plant height, ear length, number of kernels per ear and weight of single fresh ear were highest at 100% E pan whereas the lowest values were observed at 70% E pan in both years. Water savings varied between 10.91% and 31.15% depending on water deficiency treatments. The highest fresh ear yields (12.76 and 12.44 t ha -1) were obtained at 100% E pan and the minimum fresh ear yields (7.90 and 7.31 t ha -1) at 70% E pan in both years. Fresh ear yields at 100% and 90% E pan were not significantly different. Despite reduction in fresh ear yield because of deficit irrigation, 80% E pan had no negative effect on the number of marketable ears. In conclusion, deficit drip irrigation up to 20% (80% E pan) can be acceptable for sweet corn (cv. Jubilee) production in the southeastern region of Turkey.
