Comparatively, Zambian smallholder cassava productivity is low. Zambian farmers produce 6 ton ha-1 , compared to 20–25 ton ha-1 in Zambia. Therefore, understanding smallholder farmers' poor yields is necessary to develop cassava cropping systems for yield intensification. In this study, field...

Cassava (Manihot esculenta Crantz) is a staple food and a main source of income for several smallholder farmers. However, its yields are low at about 6 t/ha, lower than actual yields of 20–25 t/ha in Zambia. The main objective of the study was to assess sustainable management practices in cassava...

Organic amendments have been known to improve soil physical and chemical properties in sub-Saharan Africa. However, research information on how organic amendments affect aggregate stability and the degree of their effects in comparison to others is indaquate in Zambia. The study was therefore...

Common bean and groundnut are an important source of protein, fat, carbohydrates, vitamins and minerals for both humans and livestock. These legumes are produced mostly by smallholder farmers whose current yields are far below the potential yield of 2 t/ha for both legumes due to biological...

Zambia has soils with low plant available nutrients due to leaching, depletion of organic matter and acidification. One way of addressing this situation is by the application of organic materials such as aqueous neem leaf extract. No known documented research has been conducted in Zambia to...

This study was carried out during the 2008/09 season under irrigated conditions. It was conducted at the University of Zambia (UNZA), School of Agricultural Sciences Field Station. The objective of the study was to determine the yield response of selected varieties of a leafy vegetable, Rape...
