2	538.23^a	17.11^b	38.01^a
4	544.10^a	17.47^ab	37.80^a
6	560.40^a	18.13^a	36.83^a
8	567.76^a	18.22^a	37.15^a
LSD (0.05)	33.136	0.938	2.021
NPS (kg·ha^−1)
0	520.50^b	16.75^b	37.21^a
50	553.30^a	17.61^a	37.05^a
100	564.90^a	18.14^a	37.96^a
LSD (0.05)	25.667	0.727	1.565
CV (%)	6.30	5.60	5.60

LSD = least significant difference; CV = coefficient of variation (%). Means in the same column followed by the same letter(s) are not statistically significant different at 5% probability level.
