The success of inland valley crop production in humid and subhumid areas of subSaharan Africa depends on the availability of appropriate crop varieties with some tolerance to excess moisture. Performance of upland crop associations [cassava (Manihot esculenta) + sweet potato (Ipomoea batatas) and...

The extent to which agricultural technologies have had an impact in the humid forest zone remains questionable as adoption levels have been low. The technologies developed emphasized on maintaining soil fertility and crop yields in short fallow systems. This chapter defines the problems and oppor...

Plantain (Musa spp.) cropping systems of Southern Cameroon can beseparated into those based on forest clearing and those based on land already used.Plantain is a major crop starting the forest clearing cycle. It is more than other foodcrops grown for commercial reasons. However, varietal choice f...

To evaluate the soil‐fertility sustainability of the fallow systems, nutrient concentrations and NH4+‐N mineralization were determined in different soil and fallow types in the humid forest zone of southern Cameroon. Two experiments were conducted, the first comprised planted leguminous tree Call...

Little research on slash and burn systems has investigated whether effects of burning are due to the fire per se or to the removal of biomass from the soil surface. In this experiment, the aim was to assess the effects of burning versus no burning and mulching versus no mulching on maize yields, ...

Chromolaena odorata (Siam weed; Asteraceae), is an important weed in most cropping systems of humid West and Central Africa. In plantain (Musa spp.), the most important cash food crop in Cameroon, the traditional system of slash and burn of old secondary forest with long phases of weed-free crop ...

Fallows improve soil fertility and allow sustainable agriculture. Soil fertility was assessed under different types of fallow through pH, nutrient concentrations and particulate organic matter (POM) quantity and quality. The two year-fallows were under Chromolaena odorata, Calliandra calothyrsus ...
