Response of mononychellus tanajoa (acari: tetranychidae) to cropping systems, cultivars, and pest Interventions por Toko, M., Yaninek, J.S., O'Neil, R.J.

“…The effects of cropping systems (cassava monocropped and intercropped with maize), pest interventions (spray of acaricide and release of an exotic phytoseiid) and cultivars (‘Agric’ and ‘TMS 30572’) on the population dynamics of the green mite, Mononychellus tanajoa (Bondar), were evaluated in 2 locations (Dogbo and Intemational Institute of Tropical Agriculture) in Benin Republic, West Africa. Maize and cassava were intercropped at the beginning of the wet season. …”

Acceptability of forage legumes for improved fallows - first experiences of agro-pastoralists in subhumid southwest Nigeria por Muhr, L., Tarawali, Shirley A., Peters, Michael, Schultze-Kraft, Rainer

“…In the process of developing an improved fallow system based on forage legumes, the potential interest of crop-livestock farmers in enhancing soil fertility restoration and dry-season feed supply was assessed during a socio-economic study on 11 farms of settled agro-pastoralists in the subhumid zone of West Africa. Simultaneously, eight farmers in the group participated in simple and largely farmer-managed on-farm experiments testing the establishment of selected forage legumes on fallow land. …”

In West Africa, for example, labour supplied by women for rice cultivation varies from 3% for floating rice in Mali, to 80-100% in mangrove-swamp rice in The Gambia and Liberia, where women participate in most of the activities and undertake postharvest processing of the crop (Huvio, 1998). …”
