Maize was relay cropped with the cover crops Mucuna pruriens or Pueraria phaseoloides for between 1 and 7 consecutive years in three sites, Ngoungoumou, located in an area of low land use intensity (LUI), about 100 km away from the next major market, and at Evendissi and Andok, in a medium LUI ar...
The contribution of the cover crops Mucuna pruriens var. utilis and Pueraria phaseoloides to the N balance of a sole maize relay cropping system was estimated. Over 4 consecutive years, amounts of N in 8-9 months old aboveground M. pruriens, P. phaseoloides and natural fallow biomass and litter w...
Topsoil (0–15 cm) bulk density, aggregate stability, soil dispersibility, water retention and infiltration were measured between 1989 and 1996 on an Alfisol under rehabilitation in southwestern Nigeria. The planted leguminous species were Pueraria phaseoloides, Senna siamea, Leucaena leucocephala...
With increasing population densities, food production needs to be increased. A common response of farmers is to shorten fallow periods, which can lead to a decline in crop yields, due to incomplete nutrient replenishment. However, whether farmers change their management of soil and nutrients acco...
Earthworm surface cast production and nutrient turnover through casts were measured for 3 years in a 17-year-old timber plantation in southern Cameroon after selective reduction to two timber stand densities (TSDs) and understorey cropping with plantain and tannia. Neither understorey cropping no...
Maize/cassava were intercropped between hedgerows of Senna spectabilis [(DC.) Irwin and Barneby], Flemingia macrophylla [(Willd.) Merrill] and Dactyladenia barteri [(Hook f ex Oliv.) Engl.] for five consecutive years on an Ultisol in southern Cameroon. Crop yields and hedgerow biomass production ...
An intercrop of maize and cassava was cultivated for six consecutive years from 1990/91 to 1995/96. This paper reports on crop performance from the fourth to the sixth year in alley cropping with Senna spectabilis and in a no-tree control, with and without tillage. Maize grain yield increased sig...
Deforestation in the humid tropics poses an increasing threat to natural forests and future timber supplies. Smallholder slash and burn farming and timber extraction are the major causes of deforestation in the Congo basin. Therefore, the feasibility of an alternative to slash and burn, the combi...
Data are presented for termite assemblages across an anthropogenic disturbance gradient in the humid forest zone of West and Central Africa. Sampling was by standardised 100m × 2m transects in: primary forest, several ages of regenerating forest, agroforestry plots, short fallows, mixed food crop...
