Insecticide dissipation from soil and plant surfaces in tropical horticulture of southern Benin, West Africa por Rosendahl, I., Laabs, V., Atcha-Ahowé, C., James, B., Amelung, Wulf

“…The objective of this study therefore was to study the fate of pesticides in two representativehorticultural soils (Acrisol and Arenosol) and plants (Solanum macrocarponL.) after field applicationand thus to gain first insight on environmental persistence and dispersion of typical insecticides used invegetable horticulture in Benin, West Africa. On plant surfaces, dissipation was rapid with half livesranging from 2 to 87 h (a-endosulfan <b-endosulfan < deltamethrin). …”

Characterisation of a germplasm collection of the tropical pasture legume Centrosema brasilianum in subhumid West Africa por Peters, M., Kramer, H., Tarawali, Shirley A., Schultze-Kraft, Rainer

“…Benth. was assessed between 1993 and 1995 in northern Nigeria to complement existing knowledge on the genetic diversity of this species and to identify accessions with high agronomic potential for subhumid west Africa. The excellent nutritive value and good dry matter productivity of C. brasilianum and its outstanding ability to remain green over extended dry periods confirmed its potential as an important forage resource, especially for the dry season, and indicated its possible role in soil conservation. …”

Soil water depletion under various leguminous cover crops in the derived savanna of west africa por Salako, F.K., Tian, G.

“…Therefore, a study was carried out at Alabata, Ibadan, southwestern Nigeria, to evaluate the effects of leguminous cover crops on soil water suctions in 1993 and 1994 in order to assess the possibility of integrating them into the farming systems of the savanna zone of West Africa. In 1993, 13 leguminous cover crops (Aeschynomene histrix, Centrosema brasilianum, Centrosema pascuorum, Chamaecrista rotundifolia, Cajanus cajan, Crotalaria verrucosa, Crotalaria ochroleuca, Lablab purpureus, Mucuna pruriens, Psophocarpus palustris, Pseudovigna argentea, Pueraria phaseoloides and Stylosanthes hamata) were planted in a randomized complete block design with four replications. …”
