Productivity of Two Sweet Potato Varieties in the Nigerian Savanna

Productivity of Two Sweet Potato Varieties as Affected by Minero-Organic Fertilizer and Stem Cutting Length in the Nigerian Savanna. The Research was Carried out in 2015 and 2016 Wet Seasons in the Sudan and Guinea Agro-Ecological Zones of Nigeria. The Two Varieties of Sweet Potato Used in the Research were Dan-Zaria Variety (Local Variety) and Mothers Delight (Improved Variety). The Parameters Used in the Study were Variety Minero-Organic Fertilizer and Stem cutting length. The Rates of Minero-Organic Fertilizer used were control 300kg/ha and 600kg/ha.
