Variation in water availability is a major source of risk for agricultural productivity and food security in South Asia. Three hundred and thirty expert informants were surveyed during 2008-09 to determine the relative ...
Nitrogen effects on maize yield following groundnut in rotation on smallholder farms in sub-humid Zimbabwe
Rotating maize (Zea mays L.) with groundnut (Arachis hypogaea L.) has been proposed as a way to maintain soil fertility and prevent maize productivity declines in the smallholder cropping systems of sub-humid Zimbabwe. ...
The sustainability of a groundnut plus maize rotation over 12 years on smallholder farms in the sub-humid zone of Zimbabwe
An experiment was conducted on four smallholder farms and on-station in the sub-humid zone of northeast Zimbabwe for 12 years to assess how the rotation of groundnut with NPK-fertilized and unfertilized maize affected the ...
Maize adaptive research: achievements and prospects in Southern Africa
In the last six to eight years, farming systems adaptive research has contributed much to the understanding of maize production constraints on smallholder farms in southern Africa. It has contributed less to the development ...
Farmers' taxonomies as a participatory diagnostic tool: Soil fertility management in Chihota, Zimbabwe
Soil infertility is a major constraint to food production in the communal areas of Zimbabwe. Smallholders in the region recognise the problems of low soil fertility and have devised ways of coping with them. This study ...
