Rainfed smallholder agriculture in semi-arid areas of southern Africa is subject to numerous
constraints. These include low rainfall with high spatial and temporal variability, and …

Intercropping cereals with legumes can potentially enhance productivity and soil fertility.
There is limited experimental evidence on the mechanisms underlying benefits or risks in …

Constraints to effective weed management may be the main reason for the small area under
minimum tillage (MT) in smallholder farming in southern Africa. The effect of maize residue …

Continuous conventional tillage coupled with unsystematic cereal/legume rotations has
promoted low crop productivity on smallholder farms. A multi-locational study was …

The productivity and residual benefits of four grain legumes to sorghum (Sorghum bicolor)
grown in rotation were measured under semi-arid conditions over three cropping seasons …

Planting basins and ripper tillage practices are major components of the recently introduced
conservation agriculture package that is being extensively promoted for smallholder farming …

Sustainable crop intensification in sub-Saharan Africa cannot be achieved if farmers
cultivate inherently infertile soils that are deficient in key essential nutrients, such as nitrogen …

This study aimed to create a model to identify land suitable for growing sunn hemp
(Crotalaria juncea) and pigeon pea (Cajanus cajan) in the Okavango River basin of the …

Cassava is an important crop in Africa. This thesis focuses on cassava production in the mid
altitude zone of East Africa, an area characterized by high population densities, bimodal …

General belief has it that cassava is (i) a subsistence crop, grown to avoid hunger (ii) by poor
farmers,(iii) predominantly as an intercrop,(iv) requiring less labour than other crops and (v) …
