Field experiment was carried out at two sites in Akure in the rainforest zone of Southwest Nigeria to study relative effect of combined use of sawdust ash (SDA) and urea (U) on soil chemical properties, nutrient status, growth and fruit yield of tomato (Lycopersicon esculantum Mill). The soils in experimental sites were low in nitrogen and phosphorous. The treatments replicated three times on tomato seedlings were the control (no SDA, no urea), 240 kg ha U, 4.5 t ha SDA+ 60 kg ha U, 3.0 t ha SDA+ 120 kg ha U, 1.5 t ha SDA+-1-1-1-1-1-1 180 kg ha U, and 6 t ha SDA. The SDA urea and their co application increased soil organic matter (OM),-1-1 N, P, K, Ca and Mg relative to the control. The SDA gave highest soil pH, OM, available P, exchangeable K, Ca and Mg. Urea reduced soil pH. The SDA, Urea and their coapplications at r educed levels increased leaf N, P, KM Ca and Mg controls relative to control. Urea gave highest leaf N, while SDA gave highest leaf P, Ca and Mg. The SDA, urea and their combined use increase plant height, number of leaves, stem girth, root and leaf weight, biomats and number and weight of fruits. Urea gave highest values of fruit and number of fruits, and was followed by SDA and 1.5 t ha SDA+ 180 kg ha U respectively. Compared with control,-1-1 urea, 6t ha SDA, 1.5 t ha SDA+ 180kg ha U, 3.0 t ha SDA+ 120 kg ha U, 4.5 t ha SDA+ 60 kg-1-1-1-1-1-1 ha U increased fruit weight by 103, 81, 67, 56 and 47% respectively. The equivalent increases in number-1 of fruits were 236, 164, 136, 118 and 55%. It is concluded that SDA can be used to complement urea in tomato production but cannot replace urea.
