LSD (0.05)	15.03	0.34	0.19	2.04
P rates (kg ha^−1)
0	103.87	3.96	2.96	12.33
10	100.52	3.54	2.92	10.66
20	103.36	3.8	3.08	11.63

LSD (0.05)	NS	NS	NS	NS
CV (%)	19.16	11.83	8.27	23.11

Means followed by the same letters are not significantly different at the 5% level of significance. VL = vine length (cm), VIL = vine internodes length (cm), VD = vine diameter (cm), VN = vine number, CV = coefficient of variation, and LSD = least significant difference at 5% probability level.
