The necessary data was collected by interviewing the smallholders and conducting inventory of the stands. The data was analyzed with descriptive statistics, Mann-Whitney tests and Spearman correlations. More silvicultural practices were conducted by A. mangium planters with larger areas. Most of the smallholders practiced the suggested silvicultural activities. Productivity was affected by pruning in medium quality sites. This research recommends that smallholders were supported with incentives for the plantation establishment, education for smallholders in silvicultural techniques, organization and development activities for the wider market.展开更多

This situation is strengthened by the fallow periods shortening （and even suppression） in the southern Benin in general, because of demographic pressure. The promotion of some improved fallow technologies （IFT） was then launched some decades ago. This study focused on two IFT of high agro-ecological value, Mucuna pruriens and Acacia auriculiformis, in order to determine the influence of the farmers＇ wellbeing state on their farming systems in general, and on the adoption level of these two technologies in Godohou village （southern Benin）. The data analysis revealed that： There was no significant difference between the farmers＇ amount knowing the agronomic and ecological value of Mucuna pruriens and Acacia auriculiformis from a level of prosperity to another; Three wealth levels were distinguished： The poor class （Ayatonon class）, the less poor class （Metchivo-Houedeka class） and the non poor class （Hotonon class） which represented respectively 35.4%, 55.9% and 8.7%;The adoption rate of Mucuna and Acacia fallow was globally low in Godohou village （25.7%）, but this adoption rate was lesser in the poorest class than in all other classes. This trend was confirmed if we integrate a global agro-ecological analysis of the farming systems practiced by the farmers.展开更多
