Evaluation of some Bread Wheat Cultivars Under Irrigation Intervals 1: Grain Yield, Its Attributes and Water Use Efficiency

Abstract

This study was performed at El-Gemmeiza Agricultural Research Station (ARC), El-Gharbia Governorate, Egypt, during 2019/2020 and 2020/2021 growing seasons to evaluate effects of three irrigation intervals on grain yield and yield components and water use efficiency of ten wheat cultivars. Four replications of a split-plot design were carried out, the main plots were included three irrigation intervals i.e., irrigation every 20, 30 and 40 days and the ten bread wheat cultivars i.e.,
