The objective of this study is to evaluate the effectiveness of composts on the productivity of maize (Zea mays L.) by identifying the optimal dose to obtain maximum productivity. The compost used was produced from fermentable fractions of household waste from the city of Lomé. A device in randomized complete blocks with two repetitions comprising five doses of compost (To = control, T1 = 25 t. ha-1, T2 = 50 t. ha-1, T3 = 75 t. ha-1, T4 = 100 t. ha-1) was used. The treatment with compost have been done on elementary plots of 10 m2 each. Sowing is done in three rows of 25 feet each. On each line, the maize plants are separated by 0.20 m and the lines are spaced 0.80 m apart. The average density is 75000 feet per hectare to ensure good ventilation. The results obtained showed that the yield increased according to the doses of compost provided but decreased from 50 t. ha-1. There is therefore a compost use limit of between 25 t. ha-1 and 50 t. ha-1. Maize farmers could use compost for sustainable and effective fertilization to increase their production while preserving soil quality.
