Effect of irrigation treatments onmaize (Zea mays L.)Yield & yield components during two growing seasons.

Abstract

Effect of five irrigation treatments on the yield and yield component of maize variety TALAR were studied at Gurdarash Research station. College of Agriculture, Erbil-Iraq during spring and fall season 2011.The result Showed significant differences among irrigation treatments for a must studied characters ear length, grain yield/plant, kernel/ear, 250 kernel weight and yield at both seasons. In spring season the total irrigation water used was about (3503 L/4m²), the value of must character were decreased. While in fall season the total irrigation water was about (3177 L/4m²) and the value of all characters were increased, the irrigation water was profitable for plant even at late maturity, which caused the higher irrigation efficiency in fall season than spring season according to crop productivity and less irrigation water used.
