Dendrometric and Structural Characterization of Moringa Oleifera Agroecosystems in Central Africa: A Case Study from Cameroon

Abstract

The main objective of this study is to analyze the dendrometric and structural parameters of Moringa oleifera populations in the agroecosystems of the Far North Cameroon. The method quadrat 25 m × 25 m was undertaken to evaluate dendrometric parameters using the average diameter, average height and radius of the average crown. The population structure of M. oleifera is determined by density, basal area and rate of aerial cover. A total of 288 plots have been installed. The data collection was carried out in an area of 1 ha per plot. The parameters calculated in three subdivisions (Diamaré, MayoDanay and Mayo-Tsanaga) showed that the average diameter varies from5.63 ± 2.74 to 17.7 ± 7.43 cm; the average height of 3.37 ± 0,80 to 6.21 ± 1.75 m; an average crown of 1,50 ± 0,75 à 3,16 ± 1,23 m.With an average density between707 ± 16.64 and 1457 ± 45.41 stems/ha; an average basal area between 1.70 ± 0.02 and 10.86 ± 0.009 m²/ha and an aerial cover between 13.48 et 54.93%. The population distribution showed a predominance of individuals with a diameters of between 5 and 10 cm with a height of between 2 and 6 m and a crown radius of less than 2m reflecting a young population. The result show a significant correlation between diameter, height, and crown (p= 0,0001) in the three subdivisions. This study can be used as part of the sustainable management of this species in Cameroon.
