Abstract

Deciding over the suitable value and irrigation scheduling of CORN (hybrid SC.704) in summer by utilization of class A EVAPORATION PAN is the focal point of this research. Accordingly, a project was conducted in the form of stadistical perfect accidendal block in four repetions and four TREATMENTs in 1383 on Ahvaz Azad university research land situated in Choneibeh. The irrigation TREATMENT had four levels of T1, T2, T3 and T4 in class A EVAPORATION PAN contains of four levels 50, 75, 100 and 150 mm carried out in split plot. The suitable irrigation period according to the best reseach from the point performance and its components was chosen and the total amount of water in the taking period defines the depth of irrigation. The soil texture is clay lomy silty and the internal soil is silty clay. According to the amount of the accumulated evaporation from class A EVAPORATION PAN and taking the plant coefficient (Kc) into consideration, the amount of evapotrans piration the needed was calculated and the amount of needed water for plot was measured by water counter. Then a comparison between the means by making use of Donken multi domains test was done and in this way the prior TREATMENT was selected. Accordingly the most suitable time for irrigation of summer CORN in Ahvaz was after 50 mm of accumulated evaporation from class A EVAPORATION PAN which equals ten irrigation in the growing period. So in order to acquire 12 tons of seed yield in each hectar, at least 9600 m^3 of water for every hectar is needed. However, with the equal amount of water, with 3 times decreace in irrigation in TREATMENT T2 in comparison with T1, a performance near to 11 tons and with five times decreace in irrigation and ten tons in TREATMENT T3 can be attainable.
