Daftar Isi:
- 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.
