Yield and Profitability of Sweet Potato (Ipomoea batatas (L.) Lam) as a Function of Increasing Levels of Phosphorus and Varieties in Southern Ethiopia

Table 4

Effect of varieties and P rates on the number of roots per plant of sweet potato at Tadissa, Boloso Sore District, Southern Ethiopia, 2016.

Varieties	NRPP	P rates (kg ha^−1)	NRPP
Awassa-83	6.49^a	0	4.83
Kulfo	2.39^b	10	5.01
Local	6.32^a	20	5.08
		30	5.39
		40	5.01
LSD (0.05)	0.46	LSD	NS
CV (%)	12.15	CV (%)	12.15

Means followed by the same letters are not significantly different at the 5% level of significance. LSD = least significant difference, CV = coefficient of variation, and NRPP = number of roots per plant.
