Comparison of Zea mays water consumption under two irrigation methods of surge and continuous furrow in the Eghlid plain

The study was conducted to evaluate surge irrigation against continuous irrigation in terms of irrigation and water use to produce Zea Mays (var. indentata SC704). The experiments were conducted in the loam clay soil of Agriculture Research Station Islamic Azad University Eglid (Fars province). The furrows were 120m long and 0.6m center-center width with 0.002 m/m of slop. The treatments consisted of randomized complete block design (RCB) of four treatments CF (continuous flow) and SF surge flow where SF1 (15 min on-off time), SF2 (20 min on-off time) and SF3 (30 min on-off time) with three replication. The results showed that based on water use, difference between CF and SF treatments was significant. As well as the average of water use in SF2 and SF3 treatments were lower than the other treatments. But based on yield did not exit any significant difference between CF and SF3. Thus the SF3 treatment is recommended due to less water use and high yield compared to the other treatments.
