Abstract:

Three different ash materials (kitchen wood ash –KWA, oil
palm bunch ash-PBA and timber saw mill ash- SDA) applied at
the rates of 0, 2, 4, 6 and 8 tons/ha were incorporated in
an Ultisol planted with sweetpotato to evaluate their
effects on yield and crop quality, using sweet potato as a
test crop. The soil was acidic and deficient in N, % O.C.,
K, Ca, Mg and Na. Considering the total tuber weight of
sweet potato, all the ash sources increased yields over the
control, but only the KWA produced a significant (P<0.05)
increase in yield over the control. Total tuber weight of
sweet potato increased with amount of ash applied; 4 tons/ha
which gave 53.76 % increase in the total tuber weight was
optimum. SDA also, significantly (P<0.05) increased the
nitrogen, phosphorus and potassium contents of sweet potato.
8 tons/ha of the same gave the highest contents of N, P and
K.
 
Key words: yield, nutrient composition, sweet potato,
sources of ash.
