The management of sandy soil in Bateke plateau to feed Kinshasa population in continued growth, is one of the problems that arises in this urban peripheral agriculture. Agroforestry in time, alternating trees and crops on the same land was used as technical means to increase fertility and production. However, agricultural practice in the long term at Bateke plateau showed that agroforestry was not able alone to ensure continuity of production on the same land. In this study, we tested the effect of biochar associated with litter from an agroforestry system could have on improving maize production in Bateke plateau. We observed that forty one and five months respectively after application of biochar and litter maize production was influenced favorably. Among all combinations of biochar doses (0, 2, 4 and 8 kg / m2) and Acacia mangium litter doses (0, 5, 10 and 20 t / ha), the combination of 4 Kg / m2 of biochar with 20 t / ha of litter was the best with 2019 kg / ha of maize cobs with spathe. Moreover, the presence of the clipped hedge has had an effect on the stems and maize cobs differently on plants in his neighborhood and those in the middle of the experimental plot.

Abstract: (french)
La gestion des sols sableux du plateau de Batéké, en vue de nourrir la population kinoise en croissance continue, est l’un des problèmes qui se pose à l’agriculture de ce milieu périurbain. L’agroforesterie dans le temps, alternant arbres et cultures sur un même sol, a été utilisée comme moyen technique pour augmenter la fertilité et par ce fait la production. Cependant, la pratique agricole de longue durée au plateau de Batéké a montré que cette agroforesterie n’a pas été capable à elle seule d’assurer la continuité de la production sur un même terrain. Dans cette étude, nous avons testé l’effet que le biochar associé à la litière provenant d’un système agroforestier pouvait avoir sur l’amélioration de la production du maïs au plateau de Batéké. Nous avons observé que 41 et cinq mois après les applications respectivement du biochar et de la litière la production du maïs a été influencée favorablement. De toutes les combinaisons de doses du biochar (0, 2, 4 et 8 kg/m2) et de la litière d’Acacia mangium (0, 5, 10 et 20 t/ha), la combinaison de 4 Kg/m2 de biochar avec 20t/ha de litière a été la meilleure avec 2019 kg/ha d’épis spathés de maïs. De plus, la présence de la haie tondue a eu de l’effet sur les tiges et les épis de maïs de manière différente sur les plantes de son voisinage et ceux du milieu de la parcelle expérimentale.
