Treatments were as follows: fertilization during leaf-expansion period, fertilization during green-leaf period, and no fertilizer. Results showed that individual leaf area, thousand-leaf weight, and leaf distribution were relatively stable with little influence from fertilization. Fertilization during leaf-expansion compared to the green leaf period significantly increased leaf number, leaf weight per plant, and leaf area index. Fertilization during led-expansion also significantly increased the total weight of leaves corresponding to each branch. The 14th to the 17th branches had the largest number of leaves in the canopy with fertilization increasing the weight of each branch but not changing the center of the canopy.
