- Means followed by the same letters for the same parameter are not significantly different at P ≤ 0.05
- CV Coefficient of variation, NR nitrogen rate, NT time of nitrogen application
- T1 = N application of ½ at sowing and ½ at tillering; T2 = N application at tillering; T3 = N application of ½ at tillering and ½ booting; T4 = N application 1/3 at sowing, 1/3 at tillering and 1/3 at booting; and T5 = N application ¼ at sowing, ½ at tillering and ¼ at booting
