B. Duguma et J. Tonye, SCREENING OF MULTIPURPOSE TREE AND SHRUB SPECIES FOR AGROFORESTRY IN THE HUMID LOWLANDS OF CAMEROON, Forest ecology and management, 64(2-3), 1994, pp. 135-143
A field screening trial Of ten exotic multipurpose trees and shrubs wa
s initiated in August 1987 in Yaounde, Cameroon. The objective of the
study was to identify adaptable species with desirable traits that cou
ld be used for agroforestry systems recommended for the humid lowlands
of Cameroon. The species included were Acacia auriculiformis, Acacia
mangium, Calliandra calothyrsus, Cassia javanica, Cassia siamea, Gliri
cidia sepium, Leucaena leucocephala, Paraserianthes falcataria, Sesban
ia grandiflora and Sesbania sesban. Results suggested that the two Ses
bania species were poorly adapted to the region (based on survival rat
e). P. falcataria and Calliandra calothyrsus were among the fastest gr
owing species and their foliage had high nutrient values, making them
promising candidates for agroforestry technologies aimed at improving
soil fertility. However, the coppicing ability of P. falcataria was be
average. Primary growth of the Acacia species was relatively high, bu
t they were poor coppicers. They could be useful as shade trees on coc
oa or coffee farms, but are not suitable for hedgerow intercropping.
