La concurrence des mauvaises herbes est un obstacle à la rentabilité de la production du manioc. La connaissance des espèces de mauvaises herbes qui affectent négativement la productivité du manioc est essentielle pour une gestion efficace. Une étude a été conduite entre mai et juin 2014 et 2015 ...

Changes in soil properties and nematode population status under Flemingia macrophylla [(Willd.) Merrill], Pueraria phaseoloides (Roxb.) Benth, and natural bush fallows were assessed in three villages in southern Cameroon. In each village, experiments were set up in a 4–5 year-old bush fallow domi...

Earthworms can have positive effects upon crop growth in the tropics. If soils are to be managed sustainably, then more attention should be paid to the effects of cultivation and cropping practices upon earthworms. When forest vegetation is cleared, slashed, burned and land is tilled and cultivat...

We evaluated if cropping maize immediately after plantain is affected by the previous plantain systems and if tillage or N fertilizer would affect maize growth and grain yield and soil physical properties. The on-farm experiment was conducted at Mfou in the central Cameroon on a clayey, kaoliniti...

Zonocerus variegatus (L.) is known as an agricultural pest in Central Africa. Since legumes are introduced in the Chromolaena odorata fallows in the southern Cameroon as short fallow improvement strategies, we evaluated the abundance of Z. variegatus in short fallows (natural versus planted legum...

Plantain (Musa spp.) is the most important food cash crop in SouthernCameroon. Farmers suffer severe income losses through yield losses due to pest anddisease infestation of suckers planted without any measure taken to remove pestsand diseases. This paper reports on the first trial conducted unde...

Crop management without fertilizer input, which is commonly practiced by most farmers in the humid forest zone of West and Central Africa, requires soil fertility replenishment during a fallow period. Hypothetical relationships between fallow length and crop yields assume, that after the cropping...

Two methods of intensifying crop production in ‘no-external-input’ slash and burn crop fallow rotation systems: increased crop density and increased cropping frequency, were tested on an Ultisol in southern Cameroon. Two common fallow types, secondary forest (forest fallow) and young...

Plantain is an important staple in West and Central Africa, where it is predominantly grown by smallholder farmers. On-farm data are rare but yields are considered to be low. We collated actual yields in the region, reviewed regional plantain research published from 1976 to 2013, then estimated w...
