The research was carried out at the National Horticultural Research Institute, Ibadan, (Lat. 70 30êž‹N; Long. 30 50ËˆE) during the 2011 and 2012 cropping seasons. The experiments were design as 2x2x5 factorial arranged in splitâ€“split plots with the main effects comprising of sole and intercropped tomato, the sub-plots made up of two tomato varieties (Uc82B and Ibadan local) and the sub-sub plots consisted of five soil amendments (0, 60 and 120kg N/ha NPK and 10 and 20ton/ha poultry manure). The intercropped tomato was planted with a maize cultivar SAMMAZ 14. Data collected include plant height, number of leaves per plant and fruits yield of tomato. All data were analyzed using the analysis of variance (ANOVA) and significant means were separated with the least significant difference at 5% probability level (LSD0.05). Results showed plant growth and fruits yield were reduced in the intercropped tomato. Soil amendments either by inorganic or organic means significantly improved the plant growth and fruits yield; Ibadan local variety showed better plant growth and higher fruits yield than the Uc82B.
