An experiment was conducted to determine the nutrient contents and manurial value of  biocompost, collected from Matiari Sugar Mill, Matiari and analyzed for macro nutrients N, P and K. The biocompost was evaluated in a pot experiment on maize crop  with eight treatments in factorial combinations of two rates of biocompost (0 and 10 tons ha-1) and four fertilizer treatments (0-0-0, 150-0-0, 150-75-0 and 150-75-60 kg ha-1 N, P and K) . The treatments were replicated three times in a randomized complete block design and maize was grown for 7 weeks. The soil was a clay loam (31% clay) with EC 0.35 dSm-1, pH 7.87, low in organic matter (0.80%) and Olsen P (7.0 mg kg-1) and high in NH4OAC-K (320 mg kg-1). The nutrient contents of biocompost were 1.8% N, 1.83% P and 0.9% K. Results revealed that there were pronounced positive effects of addition of biocompost, as well as N on plant height and dry weights of maize. Plant analysis data showed that the effect biocompost and mineral fertilizers was non-significant with respect to N, P and K contents. Soil analytical data showed that the EC values of post harvest samples increased with the application of biocompost while pH was not affected. Soil organic matter, Olsen P and NH4OAC-K increased significantly with the application of biocompost. Fertilizer application also increased Olsen P and NH4OAC-K contents in soil. The results of this study showed that biocompost can be used along with mineral fertilizers to increase maize growth and dry matter yield.
