Effect of Sawdust Ash plus Urea on Maize Performance and Nutrient Status

M.A. Awodun, M.S. Otaru and S.O. Ojeniyi
Sawdust ash (SDA) is a waste from wood and sawmilling industries. Effect of SDA combined with urea was investigated in plant height, yield and nutrient content of leaves of maize in two experiments in Okene, in the Guinea Savanna zone of Nigeria. Treatments were a 4 t ha-1 SDA, b) 250 kg ha-1 urea, c) 1 t ha-1 SDA + 187.5 kg ha-1 urea/d, 2 t ha-1 + 125 kg ha-1 urea, e) 3 t ha-1 SDA + 62.5 kg ha-1 urea and f, untreated control. The SDA at 4 t ha-1 increased height of maize insignificantly. The 1 t ha-1 SDA + 187.5 kg ha-1 urea gave highest maize yield and leaf N. Compared with untreated control, DSA, combined application of reduced rates of SDA and urea, the urea alone increased leaf N, P, k, Ca and Mg concentrations. Combined application of SDA and urea is a suitable option for maize cultivation.
