The objective of this study is to investigate the influence of different K sources (KCl and K2SO4) on sunflower yield. For this purpose, a randomized block experimental design with K2SO4 and KCl sources was established in the greenhouse. The treatments were consisted of 0 (standard), 50, 100, 150 and 200 kg/ha fertilizers each with four replicates. After development, plants were harvested. The heights and weights of each plant was obtained and dried in the oven. The potassium content of each plant was measured, using flame photometer apparatus. The obtained results indicated that by increasing potassium concentration in soil, its accumulation in plant tissues was also increased. So that the best yield was in 200Kg/ha level of K2SO4 treatment and the lowest yield was in the 50Kg/ha of the KCl treatment. Also, the sulphur content increased with increasing of K2SO4 fertilizer. This study may help the integrated nutrient management for oil seed crops especially the sunflower.
