TS, JS, HS, FS, LFS and MS indicate the tillering, jointing, heading, filling, late filling and maturity stages of rice, respectively. Different lowercase letters indicate significant differences among nitrogen (N) fertilizer treatments (p < 0.05). Different uppercase letters indicate significant differences among planting density treatments (p < 0.05)
