The lowest and the highest plant water consumptions (Et) were found in I40 (240–406 mm) and I100 (348–504 mm) treatments in both years. Water deficit affected on maize fresh ear yields, yield components, quality and water use efficiencies. The lowest fresh ear yields (11515.7 and 10952.3 kg ha−1) were determined in I40 treatments in both years, respectively. The highest fresh ear yields (14857.7 and 14712.7 kg ha−1) were obtained from I100 treatments in 2011 and 2012 years, respectively.
