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 ...
Effects of conservation agriculture techniques on infiltration and soil water content in Zambia and Zimbabwe
The adoption of cropping systems (CA), based on minimal soil movement, permanent soil cover with crop residues or growing plants and crop rotation has advanced rapidly in the Americas and Australia over the last three ...
Smallholder farmer management impacts on particulate and labile carbon fractions of granitic sandy soils in Zimbabwe
Crop production in maize-based smallholder farming systems of Southern Africa is hampered by lack of options for efficiently managing limited and different quality organic nutrient resources. This study examined impacts ...
Indigenous legumes biomass quality and influence on C and N mineralization under indigenous legume fallow systems
Non-cultivated N2-fixing indigenous legumes can be harnessed to enhance soil fertility replenishment of smallholder farms. Understanding N release patterns of biomass generated by such legumes is key in managing N availability ...
Multi-site, multi-season field tests demostrate that herbicide seed-coating herbicide-resitance maize controls Striga spp. and increases yields in several African countries
Plant parasitic Striga (witchweed) species have not been controlled in susceptible host crops prior to exerting damage. High dose, localized herbicide levels can be applied on or near maize seed bearing acetolactate synthase ...
