In: Arab Universities Journal of Agricultural Science 2007.v.15(2)Summary: Two field experiments were conducted in 2004 and 2005 seasons at EI-BosaiIy farm located at Beharia Governorate, Egypt, to study the effect of three nitrogen levels 60, 120 and 180 kg/feddan applied into irrigation water "fertigation" with drip irrigation system on vegetative growth, nutrient content (N, P and K) in leaves and grain and yield of three maize (Zea mays L.) hybrids (Single Cross 10, Three Way Cross 310 and Three Way Cross 324). The experiment design was a split plot with three replications where nitrogen fertilizer levels were distributed in the main plots and maize hybrids allocated in sub plots. The obtained results indicate that the increase of nitrogen level up to 180 kg /fed significantly increased plant height, number of leaves per plant, leaf area index, grain yield and straw weight.
