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...

The agricultural sector of the Democratic Republic of Congo continues tosuffer from declining productivity after a decade of civil unrest andunderinvestment. Plantain and banana (Musa spp.) are considered the second mostimportant staple crop after cassava (Manihot esculenta). The Congo basin is a...

Result of long time alley cropping trials show that the inclusion of N2- fixing hedgerow species maintain higher levels of soil fertility than control treatment (no hedgerow) on high base status soils in the humid zone. Hedgerows contribute to nutrient cycling and higher faunal activity. With goo...

La mouche blanche (Bemisia tabaci) est le vecteur de la mosaïque et de la striure brune du manioc. Sa population a toujours été faible dans les champs de manioc. En plus, cet insecte trés polyphage, n'avait jamais constitué d'une manière directe, une menace réelle à la culture du manioc en Afriqu...

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...

Evaluation of soil aggregate stability under managed fallow systems is very relevant in the assessment of their agricultural sustainability. It is also important to identify the parameters that are most responsive to the effects of these fallow systems on aggregate stability. This study was carri...

The amounts of earthworm surface casts were monitored for 200 days after commencement of casting in three alley cropping experiments of different ages and hedgerow species. Casts were collected twice per week in transects from under the hedgerow to the middle of the interrow space. Average annual...
