Abstract
Two field experiments were carried out at the Research Farm of the Faculty of Agriculture, Assiut University, during 2008 and 2009 seasons, to study the effect of three irrigation intervals (15, 25 and 35 days) and three nitrogen fertilization rates (40, 80 and 120 kg/fed.) on the growth and yield of two maize hybrids (S.C. Watania 4 and T.W.C. 310). Increasing irrigation intervals significantly reduces maize growth and yield and its components as well as the percentage of protein and oil ingrains. This reduction in grain yield (76.28 and 63.07%) is due to irrigation every 35 days compared to irrigation every 15 days for the first and second seasons respectively. The two hybrids significantly differed in most of growth characters in both seasons and grain yield and its components in the second one with superiority of S.C. Watani4. Increasing N-rates significantly increased the growth of maize andgrain yieldand its components as well as the percentage of protein and oil in grains. Interaction between irrigation intervals and N-rates significantly affected grain yield/fed. in the first season and that highest yield, when irrigation every 15 days and application of 120 kg N/fed.
