Many subsistence farmers
find it difficult to apply the right dose of fertilizer using conventional
Kg/ha or t/ha style of recommendation that are normally interpreted to the
farmers by the Agricultural Extension Agents. 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%).
