In low-input land-use systems combining timber trees with shade-tolerant understorey crops, it is essential to establish the effects of tree density upon weeds and the contribution of weeds to competition and nutrient cycling. Adjusting tree density may alter weed competition for light, water and...

Tree litter fall was monitored for 2 years in two Terminalia ivorensis A. Chev. plantations in the humid tropics of southern Cameroon. The plantations were 6 and 17 years old when they were each thinned to two timber stand densities (TSD) and understorey food crops were introduced. Leaf litter wa...

Plantain (Musa spp. AAB, French, cv. Essong) was grown on an acid ultisol in southern Cameroon to determine yield response to (1) a hot-water treatment to control nematodes and (2) the application of fertilizer. Observations were made for 42 months. Establishment was unaffected by hot-water treat...

The impact of land use (unfertilized continuous maize cropping, unfertilized and fertilized alley cropping with maize, Gliricidia sepium tree fallow, natural fallow) on the soil organic matter (SOM) status and general soil fertility characteristics were investigated for a series of soils represen...

There are limitation to all methods currently available for estimating symbiotically fixed nitrogen. This paper evaluates the I5N dilution and N difference methods, and reports on the results of field experiments conducted with faba beans (Viciafaha) and peas (Pisum sativum). The objectives of th...
