Effets du vermicompost à base d’ordures ménagères associées aux balles de riz sur les paramètres agronomiques du maïs (Zea mays L.)

Objectives: This study aims to produce and determine the fertilizing value of vermicompost, and to measure the effects of this vermicompost on the growth and yield of corn. Methods and results: The work consisted first of all in developing a household waste compost then its associated vermicompost by inoculation of the earthworm Eudrilus eugeniae (Kinb.), and then in evaluating their effects on the production of maize through a trial conducted in the natural environment in Jean Lorougnon Guedé University of Daloa. The treatments consisted of a control consisting of fallow soil, household waste compost associated with rice husks and the corresponding vermicompost. The results revealed that vermicompost has the highest levels of N, P and K, but the lowest concentrations of Cu, Zn Guei et al., J. Appl. Biosci. 2020 Effets du vermicompost à base d’ordures ménagères associées aux balles de riz sur les paramètres agronomiques du maïs (Zea mays L.) 15863 and Pb. Corn plants grow better on vermicompost compared to compost and control. In addition, the vermicompost treatment produced root biomass (45.625 ± 1.812 kg.ha-1), the number of grains per plant (391.68 ± 17.20 kg.ha-1) and the total biomass of grain (2608.969 ± 50.914 kg.ha-1) the highest. Conclusion and application of findings: The work revealed the importance of the species Eudrilus eugeniae in the formation of a compost of good chemical quality. Farmers can use household vermicompost associated with rice hulls to improve the yield of maize crops.
