Abstract

Agriculture in the semi-arid region of Egypt is highly dependent on irrigation. The water is limited in this region and the prices of mineral fertilizer are exaggerated increases the needed to optimize its efficient use, especially in small-scale farming schemes. Thus irrigation management should be directed towards maintaining optimum moisture and nutrient concentrations within the root zone. If this objective is achieved, crops will take up their maximum amounts of water and nutrients with minimum wastage. Two field experiments, were conducted during summer 2013 and 2014 under surface drip irrigation system at Ali Mubarak experimental farm, El-Bustan area (sandy soil) toevaluate the rates of irrigation water (100% and 75% of ETp < /sub>) with Nitrogen applications forms (Urea 46%, Ammonium Sulphate 21% and Ammonium Nitrate 33.5%) compared with the recommended dose (120 N units fed-1) to obtain a formulate interaction among them, which realize the best strategy practices to get the optimum production of maize (Zea mays L.), nitrogen use efficiency and water productivity. The experimental treatments were tested using a split plot design, with three replicates. The main results could be summarized as follows: The highest grain yield (4.12Mg fed-1) was obtained in treatment (100% of ETp < /sub> × Ammonium Sulphate form). The maximum value of Nitrogen Use Efficiency (NUE) (20.58 kg grains / unit of N applied) and the minimum one was (9.32 kg grains / unit of N applied) were obtained in the following interactions among Ammonium Sulphate and (100% of ETp < /sub>) or (75% of ETp < /sub>), respectively. The values of Water productivity (WP) were increased with addition the recommended doses of Nitrogen (N) while increased by 103.8%, compared with the control. There are insignificant differences among application of N fertilizer forms on the most studied parameters. Although, the Ammonium Sulphate form consider the best N forms which gave the highest values of the most studied parameters compared to Ammonium nitrate and Urea .
