Abstract

The effects of four IRRIGATION SCHEDULING schemes on the yield and water use efficiency (WUE) of WHEAT were investigated. A two-year field experiment was carried out in Golpaygan during 1997-1999 growing seasons. The experimental design was randomized complete block, with four replications and four treatments. The treatments were irrigation after 50 (T1), 75 (T2), 100 (T3), and 125 (T4) mm of cumulative evaporation from Class A evaporation pan. Water depth was calculated based on increasing the root zone moisture to field capacity. The effect of year on seed and straw yields, PROTEIN content, and WUE was highly significant. The yields and WUE were higher in the first year, but PROTEIN content was higher in the second year. The effect of irrigation on seed and straw yields, PROTEIN content, and WUE was significant. The highest seed and straw yields were obtained from T2 (7825 and 13625 kg/ha, respectively). The highest PROTEIN content was obtained from T2, which was significantly higher than T3. WUE of T2 was significantly higher than T1. The lowest and the highest WUE were obtained from T1 (0.99 kg seed/m3) and T4 (1.24 kg seed/m3), respectively. Under present experimental condition, T2 treatment (75 mm cumulative evaporation) with total 642 mm of water, 9 irrigations, and 7825 kg/ha of grain yield and 13625 kg/ha of straw yield, was the best treatment. In this treatment, without considering the rainfall WUE was 1.22 and 2.11 kg/m3 for seed and straw, respectively.
