A study on the mineral and liquid organics fertilizations was conducted on tomato (Solanum lycopersicum L.) during short rainy season in South and Central West regions of Ivory Coast over two years to improve soil fertility and tomato yield. specifically, the treatment effects of four doses of organic fertilizer, associated or not with the mineral fertilizer on the content of the soil organic matter, the C/N ratio and the yield. The experimental design was split-plot, with four repetitions having as principal factor, the mineral fertilizer and the secondary factor, the organic fertilizer in four doses (L ha-1): C0 = 0 (control); C1 = 2.5; C2 = 3.75 and C3 = 5. The results showed that the treatment T10 (50 % mineral fertilizer + 3.75 Lha-1 of the organic fertilizer), better improved the content of the soil organic matter and the yield. However, the treatment with 3.75 L ha-1 of organic fertilizer used alone has of increased advantage the report C/N of the ground.
