  • Smart A. Ojobor


Effects of compost on maize and soil chemical properties were evaluated in 2015 at Abraka, Delta State. It was applied at 10.0 t ha-1 laid out in randomized complete block design with three replicates. Plant height, leaf area, plant girth, dry matter and maize yield were measured. Soil samples were taken for pre-planting and for post-harvest analysis. Data were subjected to analysis of variance, Duncan Multiple Range Test was used to compared means at0.05% level of significance. Results revealed that maize yields were significantly improved compared to control. Rice husk 50% + poultry manure 50% recorded the highest at both seasons followed by Rice husk 60% + poultry manure 40%. It had the highest soil pH, total N, available P and ECECwhile Rice husk 60% + poultry manure 40% had the highest organic carbon. The Rice husk 50% + poultry manure 50% is recommended for farmers in Abraka.
