TABLE 2.

The nitrogen utilization efficiencies of rice under different nitrogen treatments.

Treatments	Total nitrogen accumulation (kg ha–1)	Nitrogen physiological efficiency (kg kg–1)	Nitrogen dry matter production efficiency (kg kg–1)	Grain production efficiency (kg kg–1)
NT	265.52 ± 3.25 b	38.56 ± 1.63 b	110.98 ± 3.64 a	53.57 ± 1.14 b
NF	281.11 ± 5.43 a	47.30 ± 2.01 a	108.55 ± 4.12 a	56.75 ± 1.01 a

Different letters in columns show significant differences determined by LSD’s test (P ≤ 0.05, n = 3), data are means ± standard errors (one-way analysis of variance).
