  1. Different lower-case letters in the same column indicated significant difference among different treatment groups (ANOVA, P < 0.05) (n = 3). CK: control, NPK: all N is supplied by urea, 25PM: 25% of N by pig manure compost and 75% of N by urea, 50PM: 50% of N by pig manure compost and 50% of N by urea, 75PM: 75% of N by pig manure compost and 25% of N by urea, PM: all N is supplied by pig manure compost.
