摘　　要：<em>Tithonia diversifolia</em> is a year-round weed that decomposes rapidly after application as a soil amendment and it is more and more used in agriculture due to its numerous properties. The use of <em>Tithonia diversifolia</em> in the production of plantain vivoplants is a great opportunity for small holders’ farmers that cannot easily buy chemical inputs for yield improvement. All plant parts are used because of their richness in nutrients, mineral elements and phytochemicals without knowing which part is the most efficient. <em>Tithonia diversifolia</em> used as substrate amendment for plantain vivoplants production in nursery could promote their growth. This study aims to evaluate the effect of <em>T. diversifolia</em> leaves and stems as substrate amendment on plantain vivoplants growth promotion. The vivoplants were produced in substrates amended with <em>T. diversifolia</em> leaves, stems, combination of leaves and stems, and control without amendment. The vegetative growth parameters (number of shoots, height and diameter of shoots, area of shoots leaves) were assessed in sterilized substrate and unsterilized substrate conditions. <em>T. diversifolia</em> leaves and stems treatment increases the number of shoots, the height and the diameter of shoots as well as the area of shoots leaves compared to the control. <em>T. diversifolia</em> stems are the more efficient treatment, followed by the combination of <em>T. diversifolia</em> leaves and stems and finally the <em>T. diversifolia</em> leaves. They act as a biofertilizer promoting thus, the growth of plantain vivoplants in the nursery. All parts of <em>Tithonia diversifolia</em> can therefore be used by poor small holder farmers, as green manure for soil amendment in a green agriculture context.<em>Tithonia diversifolia</em> is a year-round weed that decomposes rapidly after application as a soil amendment and it is more and more used in agriculture due to its numerous properties.
