Changes in potato yield components

Treatment	Tuber number per plant	Tuber weight per plant (g)	Commodity rate>50 g (%)	Tuber dry weight per plant (g)
AN0	11.67 ± 0.88a	306.90 ± 0.20b	20.97 ± 1.44c	70.40 ± 0.20b
AN1	12.33 ± 0.33a	384.53 ± 0.57a	73.59 ± 3.06a	89.90 ± 2.26a
AN2	7.67 ± 0.88b	187.07 ± 4.17c	50.74 ± 3.87b	41.17 ± 7.67c

Note All the data are expressed as the means ± SEs, n = 10. According to Duncan’s test, the different lowercase letters indicate significant differences between treatments (P < 0.05). Commercial potato rate = commercially acceptable tuber weight per plant (> 50 g tuber weight)/total tuber weight per plant × 100%
