Abstract: 
Sugarcane is cultivated in extensive areas in Khuzestan It is irrigated through hydro-flume and in furrows. For an evaluation of the effect of deficit- irrigation on sugarcane yield, this experiment was conducted. The treatments consisted of the conventional irrigation method (blank), variable, every other irrigation, (by alternative furrows) and invariable every other irrigation (by fixing the furrow). Results indicated that shifting every other irrigation required the lowest amount of irrigation water in comparison with other treatments. Highest water use efficiency, quality and quantity of sugarcane belonged to the variable every other irrigation (0.72 kg of sugar per m-3 irrigation water). Conventional irrigation method consumed highest irrigation water and produced lowest quantity of sugarcane production and water use efficiency (0.48 kg of sugar m-3 irrigation water). Invariable every other furrow irrigation had a sugarcane production egual to the conventional treatment but water use efficiency was 0.14 kg m-3 more than in the common treatment. From total irrigated waters entering the furrows, about %46.4 and %53.6 were reserved in non- irrigated as against the irrigated furrows respectively.
