摘要： Sulphur fertilization is beneficial for improving growth, yield and yield determining components of field crops under a semiarid climate. The present field experiment was conducted to investigate the response to the foliar application of sulphur at various phenological stages of wheat. For this purpose, five treatments were explored i.e., control (no spray); water spray; 7.5 kg S ha(-1); 15 kg S ha(-1); 21 kg S ha(-1). The results revealed that the application of foliar sulphur at the rate of 15 kg ha(-1) increased the yield components (grain yield and biological yield) of wheat by 31 and 9% compared to control. The following trend (15 kg S ha(-1) > 21 kg S ha(-1) > 7.5 kg S ha(-1) > water spray > control) was observed for the yield components. Conversely, the application of sulphur at 21 kg ha(-1) increased the concentration of sulphur in soil and plant by 104 and 195% respectively, compared to control. A positive linear relationship was observed between soil sulphur and grain yield of wheat (R-2 = 0.76 and P < 0.0001). Furthermore, it was observed that the growth and yield of wheat increased significantly when foliar sulphur was applied in two equal splits (50% each at tillering and booting) compared to the full application at tillering and booting. It was inferred from this study that application of foliar sulphur at the rate of 15 kg ha(-1) in two equal splits (50% each at tillering and booting) improves growth and productivity of wheat in the semiarid climate.
