tape irrigation (Tape) is sample of irrigation systems in the optimum use of water effective. Determine the amount of time and irrigation with related factors is very complicated and the problems that always placed on farmers and experts has been. Of course, scientific methods and techniques applied in this field are different. The objective of this study was to evaluate the different levels of irrigation using tape irrigation systems and determine the required water in corn agriculture using Tansiometer is. Irrigation treatments included 3 treatments (intake in 1.2 FC, 1.5 FC and 1.8 FC) and Irrigation will begin if the discharge record amount of irrigation water is reached for each treatment. Another irrigation treatment Equal with the pure water requirements of plant based on meteorological data based on the Penman formula calculated after applying a crop coefficient of volume to the plant was. This project randomized complete block with 3 replications and 3 years was conducted. Using this method, control and management of farm irrigation is desired, better and more accurate. The results obtained in the 3-year test Regarding the Irrigation frequency and amount of irrigation treatments, control treatment is the highest yield and water use efficiency. However treatment of 1.2FC than other treatments, performance was close to the control treatment.
