The study of effect of furrow shape on irrigation efficiency on sugar cane fields in khouzestan province

Abstract

Population of the world is growing day by day, this will create a situation in which that the water natural resources is becoming limited. According to the classification of the International water Management Institute (IWMI), Iran is one of those countries which by the year 2025 will face a deep major water deficit.There fore, it is clear for us that we must keep in our mind, to use the water natural resources in the best possible manner. Sugarcane is one of the major crops of the tropical and semitropical climatical areas which it has been cultivated in the province of Khouzestan since the ancient times. high share of water use efficiency specially during the warm season growth in this area. The irrigation system for sugarcane crop in this study was the furrow irrigation system. This research project was conducted to varity the effectiveness of the shape furrow irrigation method for the application efficiency of the sugarcane plantations in the province of Khouzestan and the Karun Agro-Industry, Inc with three different treatment depths of 30 Cm, 22 Cm, and 16 Cm respectively, and with three replications to study the above mentioned subject. The three different above mentioned treatments had been shown by the letters A,B,C .For making these furrows for treatments A,B we had used bulldozer (with rotary chain – D6 Model) ; and for making furrows for treatment C, we had used tractor (with high flatation tire – John Deer Model) with a furrower which its’ wings had been modified.
