The objective of this trial was to evaluate the impact of the combination of manure (cow dung + DAP) and (Tithonia + DAP) on the growth and yield of the maize crop in monoculture and in association with cowpea compared to that of DAP + Urea. To assess this impact (the effects), measurements were made on the crop’s growth parameters including emergence rate, crown diameter, plant height and number of leaves. As far as production is concerned, measurements were made on the following parameters: the number of ears per plant, the number of rows per ear, the number of grains per row, the weight of a thousand grains and the yield. At the end of this study, the following results were recorded. Compared to the two cropping systems, there is no significant difference between maize monoculture and maize-cowpea combination. As for production parameters, the monoculture has a yield of 2.30 T/ha higher than the maize-cowpea combination with 1.39 T In terms of manure, it is the Tithonia + DAP combination that gives a higher yield than all the other monoculture treatments, while in the maize-cowpea combination, all the treatments show the same higher yield than the control.

Abstract: (french)
Cet essai a eu pour objectif d’évaluer l’impact de la combinaison des fumures (Bouse de vache + DAP) et (Tithonia + DAP) sur la croissance et le rendement de la culture du maïs en monoculture et en association au niébé comparé à celui de DAP + Urée. Pour évaluer cet impact (les effets), des mensurations ont été effectuées sur les paramètres de croissance de la culture notamment le taux de levée, le diamètre au collet, la hauteur de plants et le nombre de feuilles. En ce qui concerne la production, les mesures ont été effectuées sur les paramètres ci-après, le nombre d’épis par plant, le nombre de rangées par épi, nombre de grains par rangée, le poids de mille grains et le rendement. Au terme de cette étude, les résultats ci- après, ont été enregistrés. Par rapport aux deux systèmes de culture, en ce qui concerne les paramètres de croissance, il n’y a pas de différence significative entre la monoculture de maïs et l’association maïs-niébé. Quant aux paramètres de production, la monoculture affiche un rendement de 2,30 T/ha plus grand que l’association maïs-niébé avec 1,39T/ha. Au niveau de fumures, c’est l’association Tithonia + DAP qui donne un rendement de plus grand que tous les autres traitements en monoculture alors qu’en association maïs-niébé, tous les traitements affichent le même rendement plus élevé que le témoin.
