Abstract

To evaluate the effect of different irrigation systems on the growth, yield and yield components of sunflower, an experiment was conducted at Khoy Agricultural Research Center in 2003. Treatments, irrigation levels as main plots (irrigation at 70-70-70, 90-90-90, 110-110-110, 90-70-90, 110-70-110 and 110-90-110 mm evaporation from the standard pan) and cultivar as subplots in 3 levels (Record, Hisun 33 and Armavirusky) in Split Plot in the basis of Randomized Complete Block Deigns were arranged in four replications. Leaf and stem DRY WEIGHTs at HV, FA and PM were significantly reduced as irrigation intervals increased. Difference between irrigation treatments for head DRY WEIGHT was not significant at FA Increased in irrigation intervals significantly reduced seed yield. The high increase in irrigation water use, water use efficiency decreased. Consequently where the least water use efficiency (0.55) was obtained by 70-70-70 treatment, cultivars only differed for leaf DRY WEIGHT at HV stage. Armavirusky produced the least leaf DRY WEIGHT at this stage. Thus, where irrigation water is scarce, 90-90-90 irrigation treatment might be appropriate for sunflower production under condition similar to this experiment.
