Abstract

     Sugarcane is cultivated in extensive area in Khuzestan and is irrigated by hydro-flume or syphon. In a field experiment during 2005-6 at Amir Kabire Agro-Industry, of every other furrow irrigation methods was used on sugarcane to study water Volume, application efficiency and water use efficiency of sugarcane. The experiment was conducted in a Completely Randomized Design with three irrigation level treatments, conventional method (conventional, variable every other furrow (alternative-furrow) and invariable every other (fixed furrow)). This experiment was carried out on. Cp69-1062 sugarcane Varity. The results showed that total consumed water was 29848, 21281 and 20657 m3/ha for conventional, fixed-furrow and alternate-furrow irrigation for conventional, fixed-furrow and alternate-furrow methods, respectively. The total amount of water used was reduced by 30.8% and 28.7%, respectively, in the alternate and fixed-furrow irrigation treatments compared to the conventional irrigation method.
The results showed that Water application efficiency in were different levels. The water application efficiency were 41-50 percent (average %45) for conventional method and by irrigation fixed furrow were 74-83 percent (average %78) and by irrigation alternative-furrow were 77-87 percent (average %81) for 1-4 irrigations. water-use efficiency was 0.41, 0.58 and 0.7 kg/m3 (kg sugar production per m3 water used) for conventional, fixed-furrow and alternate-furrow methods, respectively.
