| Abstract: | The effects of different potassium fertilizers on growth,development and yield of Stevia rebaudiana Bertoni were experimented.The results showed: with the increasing of potassium fertilizer,the plant height,the stem thickness,the speed of leaf growth,the leaf area and the leaf yield would be increased,and the best result was got from 120 kg/ha potassium fertilizer.So the application of proper potassium fertilizer would be useful for the growth,development and leaf yield of Stevia rebaudiana. |
