M. Tarighaleslami, R. Zarghami, M. M. A. Boojar, A. A. Koliai
Abstract: To evaluate the effect of drought stress and nitrogen fertilizers on grain yield, amount of fatty acid and seed phosphorus of maize (Zea mays L.), an experiment was carried out at field experiment of Islamic Azad University, Varamin – Pishva, Iran. Result indicated that grain yield; different irrigation and nitrogen fertilizers significantly affected a mount of fatty acid and seed phosphorous. Maximum phosphorus of seed was gained by utilization of 180 k/ha nitrogen fertilizers. Utilization of 130 kg/ha and 180 kg/ha nitrogen fertilizers increased 23.34 % and 36.54 % on phosphorus of seed in compare with application of 80 kg/ha nitrogen fertilizers. Maximum of grain yield and fatty acid was obtained by irrigation after 50 mm evaporation from A class pan ) and irrigation after 200 mm evaporation from a class pan decreased 60 % on grain yield in compare with irrigation after 50 mm evaporation from A class pan interaction between different irrigation and utilization of nitrogen fertilizers treatments indicated that maximum of oil of seed was gained by irrigation after 50 mm evaporation from A class pan + application of 180 kg/ha nitrogen fertilizers.
