The agricultural sector is the largest consumer of renewable water. Improvement of water consumption pattern in this sector could reduce the pressure on water resources. To monitor water consumption in agriculture, it is necessary to study water productivity indicators in addition to monitoring irrigation efficiency, which determines the performance of irrigation systems. This research was conducted to evaluate the efficiency of two-way, closed-end furrow irrigation and the effect of irrigation management and different levels of nitrogen fertilization on yield, yield components and water productivity of maize. Because of its specific characteristics (the presence of four carbons, and in particular, its heat-soaking character), corn is closely matched to arid and semi-arid regions. Iran has a good climate diversity, including areas susceptible to corn production. Khuzestan province, due to its flat and fertile lands and high sunny hours, is suitable for planting most crops, especially corn. In many Iranian farms, traditional furrow irrigation is used for row plants.
