Crop response, tree biomass production and changes in soil fertility characteristics were monitored in a long-term (1986–2002) alley-cropping trial in Ibadan, Nigeria. The systems included two alley cropping systems with Leucaena leucocephala and Senna siamea on the one hand and a control (no-tre...

A study was conducted on a ferralsol in southern DR Congo to assess the effects of spreading Tithonia diversifolia (Td) and Tephrosia vogelii (Tv) leaves on yields of four local varieties of common bean (Kasungeji, D6 Kenya, local white bean and Kigoma). The experimental design was a randomized c...

The USDA Natural Resources Conservation Service (NRCS) developed the Mississippi River Basin Healthy Watersheds Initiative (MRBI) program to improve the health, water quality and wildlife habitat within the Mississippi River Basin. Lake Conway Point Remove (LCPR) watershed was identified as one o...

Temporal and spatial variabilities in rainfall, herbaceous production and biomass were studied over a 4-year period in a topographically diverse, arid pastoral region of northwest Kenya. A significant relation between rainfall and primary production was found, and this was applied in a manner tha...

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 ...

Although the West-African moist savanna zone has a high potential for crop production, yields on farmers' fields are, on average, far below this potential, mainly due to the low use of external sources of nutrients. Since the mid-1990s, it has become clear that in order to upgrade crop production...

Earthworm populations (predominantly Hyperiodrilus africanus and Eudrilus eugeniae) were sampled monthly for 1 yr during 1994 and 1995 in natural regrowth vegetation fallow (dominated by the natural fallow shrub Chromolaena odorata L.), planted fallow (the woody species Senna siamea Lam., Leucaen...

A collection of Sesbania sesban accessions was grown out in the field and classified using real and standardised values of 10 agronomic attributes. Clustering the accessions using the observed values of the attributes produced several groups which were mainly based on the dry matter yields after ...
