Growth and Yield of Irrigated Sweet Potato (Ipomoea batatas (L.) Lam.) As Influenced by Intra-Row Spacing and Potassium
M.B. Sokoto, M.D. Magaji and A. Singh

Abstract:
Field study was conducted in 2003/2004 and 2004/2005 dry seasons at the Usmanu Danfodiyo University Teaching and Research Fadama Farm, Sokoto to study the effects of intra-row spacing and potassium on growth and yield of sweet potato. Treatments consisted of factorial combinations of five levels of potassium (0, 50, 100, 150 and 200 kg K ha-1) and four intra-row spacings (20, 30, 40 and 50 cm) laid out in a Randomized Complete Block Design (RCBD) replicated three times. Results showed significant effect of intra-row spacing on all parameters measured. Close intra-row spacing (20 cm) produced tubers of comparatively lower weight, while wide intra-row spacing (50 cm) resulted in significantly bigger tubers. Yield increased with every increment in plant population and was highest at closest intra-row spacing (20 cm). Application of potassium had no significant effect on all the growth parameters under study but significantly increased marketable tuber and fresh tuber yield. Thus, 40 cm intra-row spacing (Due high proportion of marketable tuber) and 50 bags of 100 kg of ash/ha is recommended for use under irrigated condition in the Sokoto Fadama.
