Experiments were conducted to investigate the potential allelopathic effects of Acioa barteri, Cassia siamea, Gmelina arborea and Flemingia macrophylla leaf material on the germination of maize and early growth of cassava cuttings. Incubation of maize seeds with freshly added G. arborea and C. si...

Biomass production and nutrient uptake of all components in planted Senna
spectabilis, Dactyladenia barteri and Flemingia macrophylla hedgerow fallow were
determined after three two-year fallow phases and compared to natural fallow. Total
above-ground biomass production after each of three fallow...

To assess if the nutrient supply through planted tree fallows meets crop nutrient uptake and export, N, P, K, Ca and Mg uptake and export by a groundnut/maize/cassava intercrop was compared with the nutrient uptake by three planted fallow systems (Senna spectabilis, Flemingia macrophylla, Dactyla...

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...

Nitrogen and phosphorus uptake by maize as affected by particulate organic matter quality, soil characteristics, and landuse history for soils from the West African moist savanna zone
Soil moisture depletion during dry seasons by planted hedgerows to lower levels than under natural fallow, would reduce drainage and nutrient losses in the following rainy season when food crops are grown. The volumetric water content of the 0–150 cm soil profile was measured under planted hedger...

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...

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...
