| Abstract:
Nitrogen, phosphorus, and potassium were individually applied to blueberries at three levels (14, 28, or 42 g N per plant; 7, 14, or 21 g P per plant; and 7, 14, or 21 g K). The effects on plant growth, physiological data of leaf and yield and quality of fruit were studied. The results showed that the dry weight of 100 leaves, chlorophyll content and color value were very difference while fertilizer application was increased, but the shoot length, leaf area, weight of 100 fruits and soluble solid content had no difference. The middle level of each fertilizer treatment proved to be the best for growth and development in blueberry. | |
