Shortage of water is developing in many parts of the world. One of the most effective strategies for production and sustainability of water resources is increasing water productivity in agricultural fields(or agriculture). Energy is an essential component of the agricultural sector, which has its costs. In order to enhance economic benefits and sustainability of water resources and energy in agriculture, we illustrate the productivity parameter. Productivity means more output per unit of input(water, energy,...). Research conducted on the productivity of water and energy (electricity) in produced the seed corn, that the strategic importance of this crop in the world, is known for its high performance. This research done in agricultural company Barekat , dependent on, agro-industry Jovin( Farm Qadery) one of multiple farms in1391-1392.Water and electrical energy efficiency of maize seed were compared in the furrow, sprinkler and type irrigation systems. Irrigation water productivity in the production of seed corn for three, furrow, sprinkler (center pivot) and type irrigation system is respectively0.42, 0.46 and 0.47. Electrical energy productivity parameter (pumps and Center Pivot) for three system is 0.682 and 0.838 and 0.448 respectively. The results obtained show that the productivity of water parameters is high, in pressurized systems, particularly the type. Contrary to the impression, electrical energy productivity in the sprinkler system upper than type and furrow irrigation system .With attention to obtained parameters, we conclude in total that sprinkler systems(Center Pivot), is the best performance in terms of water and power consumption compared with furrow irrigation system and a type.
