A phenologic study of the gases agroforeteries and sylvan was done in Beni-Butembo rea with the objective to determine the cash wood agroforesteries and sylvan in Beni-Butembo area.To achieve this, we identified the agroforestry and forestry species found in peasant fields in order to establish the optimal periods for their flowering, fruiting and seed production.After analysis, 19 species were identified, most of which are atmospheric nitrogen fixing legumes and the other agroforestry for the amount of their biomass which contributes to the improvement of soil structure.Most agroforestry species flower and give fruit once or twice a year such as Grevillea robusta, Markhamia lutea, Calliandra calothyrsus, Leucaena leucocephala, while Eucalyptus sp flowers all year round hence the permanent availability of its seed and Cedrella does not fruit in high altitudes. However, all of the inventoried species bear fruit during cropping periods, which implies that there is the possibility of producing the seed twice a year, and others throughout the year. Thus, the phenology depends on local climatic and ecological conditions and from one species to another.

Abstract: (french)
Une étude sur la phénologie des essences agroforestières de la région de Beni_Butembo a été effectuée dans les périodes courant entre 2017-2020.Pour y parvenir, nous avons procédé à une identification des espèces agroforestières et sylvicoles retrouvées dans les champs paysans afin d’établir les périodes optimales de leur floraison, fructification et de la production des semences.Après analyse, 16 espèces ont été identifiées, où la plupart sont de légumineuses fixatrices d’azote atmosphérique et les autres agroforestières pour la quantité de leur biomasse qui contribue à l’amélioration de la structure du sol.La plupart des espèces agroforestières fleurissent et donnent des fruits une fois ou deux fois par an comme Grevillea robusta, Markhamia lutea, Calliandra calothyrsus, Leucaena leucocephala, tandis que l’Eucalyptus sp fleurit toute l’année d’où la disponibilité permanente de sa semence et le Cedrella ne fructifie pas dans les hautes altitudes. Toutefois la totalité des espèces inventoriées fructifient pendant les périodes culturales, ce qui implique qu’il y a possibilité de produire la semence deux fois par an, pour d’autres toute l’année. Ainsi, la phénologie dépend des conditions climatiques et écologiques locales et d’une espèce à l’autre.
