Abstract

Non-Optimal use of irrigation water, limited water resources and growing need for more food require the application of modern management techniques to save water and increase water use efficiency. This is possible only with accurate estimation of crop water requirement and timely irrigation. In this study, the differences between water use efficiency, value and yield specifications in two irrigation treatments was compared. Irrigation treatments were: irrigation based on evapotranspiration calculated by real time climatic data of the field and irrigation based upon evapotranspiration calculated by mean meteorological data of the non-reference station (Saveh city). The results showed that in the control, field 5383 m3/h water were used and the yield was 38.58 Ton/ha. Therefore, water application efficiency was 7.16 kg/m3. In the other field, these amounts were 6310.2 m3/h, 30.2 ton/ha and 4.78 kg/m3 respectively. The results of the variance showed a significant difference between the diameter of the corn and number of grains, at 5%. There were also no significant difference between the other yield properties in the field. Therefore with automated irrigation management in the field and estimation of the actual water plant requirement, in additional to reducing water use and increasing water use efficiency, not only there were no significant change in yield properties but also in some cases there was increase in quality.
