In this study made prebiotic from bioconversion of corn flour (Zea mays L.) by yeast Endomycopsis fibuligera as an alternative substitute for antibiotics. In this study, the addition of Na+, K+, Ca2+, and Mg2+ ions aimed to determine the optimum type and concentration of metal in prebiotic and testing the effect of prebiotic compounds produced on broiler weight gain. The analysis carried out included: reducing sugars, α-amylase and glucoamylase enzyme activity, protein content and cell biomass. To determine the existence of a significant effect, the analysis was carried out on broiler body weight given prebiotic compounds which were added to optimum metal ions and which were given prebiotic compounds without the addition of metal ions. The results showed that the addition of optimum metal ions was obtained on Ca2+ ions with a concentration of 0.25%, where the reducing sugar content of 0.600 mg / mL, the activity of the enzyme α-amylase and glucoamylase 0.519 and 0.287 units / mL, protein content 2.724 mg / mL, cell biomass 10.8933 mg / mL, from observations and statistical tests carried out by giving prebotic compounds by adding metal ions and giving prebiotic compounds without adding metal ions influence broiler weight gain with an average weight difference of 261 grams or 15% on day 30.

Objectifs : Cette étude se veut de produire et de déterminer la valeur fertilisante du vermicompost, et mesurer les effets de ce vermicompost sur la croissance et le rendement du maïs. Méthodologie et résultats : Les travaux ont d’abord consisté à élaborer un compost d’ordures ménagères puis son vermicompost associé par inoculation du ver de terre Eudrilus eugeniae (Kinb.), et ensuite à évaluer leurs effets sur la production du maïs à travers un essai conduit en milieu naturel au sein de l’Université Jean Lorougnon Guedé Daloa. Les traitements sont composés d’un témoin constitué d’un sol de jachère, d’un compost d’ordures ménagères associées aux balles de riz et du vermicompost correspondant. Les résultats ont révélé que le vermicompost a les teneurs les plus importantes en N, P et K, mais les plus faibles concentrations en Cu, Zn et Pb. Les plants de maïs croissent mieux sur le vermicompost par comparaison au compost et au témoin. De plus, le traitement de vermicompost a produit la biomasse racinaire (45,625 ± 1,812 kg.ha-1), le nombre de grains par plant (391,68 ± 17,20 kg.ha-1) et la biomasse totale des grains de maïs (2608,969 ± 50,914 kg.ha-1) les plus élevés. Conclusions et application des résultats : Les travaux ont révélé l’importance de l’espèce Eudrilus eugeniae dans la formation d’un compost de bonne qualité chimique. Les paysans peuvent utiliser le vermicompost d’ordures ménagères associées aux balles de riz pour améliorer le rendement des cultures de maïs. Mots clés : Vermicompost d’ordures ménagères, Balles de riz, maïs, croissance, rendement. ABSTRACT 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. Keywords: Household waste vermicompost, rice husks, maize, growth, yield.
