Abstract

Sugarcane is one of the important crops in Khuzestan provience which consumes large amount of water, specialy in the warm season.  In this study in order to optimize water consumption in a high efficiency, five treatments with three replications using randomized complete block design were applied in Karun Agro Industry, Inc  The first treatment was contained of conventional irrigation method which was used in the area (untreated as an example of witness). The second treatment was alternate furrow irrigation method during the growth season.  The treatments third, forth and fifth were irrigated by alternate furrow irrigation method in the portion of the growing season and then shifted to the conventional irrigation method for the remaining of the growing season. These treatments were sequentially included with the alternate furrow irrigation method, at the beginning of the growing season, during the mid-stage growing season and finally at the late stage of growing season.  The results indicated that there were no significant differences between all treatments, but the third treatment showed an increased of 8.02 tons/ha of sugarcane and 2.08 tons/ha sugar more than the conventional irrigation method.  With the view of percent of recovery sugar, sequentially   treatments fourth, fifth, and third have showed about 5% in surface area in better performance in comparison with the conventional method. The results also, indicated that water use efficiencies of treatments second and first were 0.51 kg/m3 and 0.38 kg/m3 respectively.  Therefore, it can be concluded that the alternate furrow irrigation system in general can cause an increase in cane yield and water productivity.
