Two field experiments were conducted to determine the effect of fertilizer types on nutrient uptake and yield of cassava using farmer simulation method at Adeyemi College Agricultural Research Farm in Ondo, southwest Nigeria. There were two sites A and B. NPK 15:15:15, Urea, Single Super Phosphate (SSP), Muriate of Potash (MOP), Wood Ash (WA) and Poultry Manure (PM) were used as treatments. Mineral fertilizers were each applied at 300kg/ha using a beer cap as a measure of the treatment while WA and PM were applied at 10t/ha using an improvised tin can. There was a control experiment without fertilizer application. The treatments were arranged on Randomized Complete Block Design and replicated three times. Compared with control, NPK, MOP, SSP, Urea, PM and WA significantly increased (p < 0.05) plant N, P uptake, cassava root yield and plant growth parameters at both locations. Among the treatments, WA recorded the highest Ca, K, Na and Mg uptake. All the treatments significantly increased whole tuber weight, peeled tuber weight and tuber length compared with control in location A and B. The percentage increase in whole tuber weight in location A was in the order of NPK (32%) > WA (24.45%) > PM (21.7%) > SSP (5.98%) > MOP (4.34) > Urea (2.7%) while the order of increase in tuber weight in location B was PM (74.4%)> WA (74%)>NPK (37%)>SSP (6%)>MOP (4%)>Urea (2%).
