Comparative performance of conservation agriculture and current smallholder farming practices in semi-arid Zimbabwe
Conservationagriculture (CA) is currently promoted in sub-humid and semi-arid areas of sub-Saharan Africa as a means to increase crop water use efficiency and stabilize yields. In this study, conducted during three consecutive ...
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 ...
Use of tine-tillage, with atrazine weed control, to permit earlier planting of maize by smallholder farmers in Zimbabwe
Because of shortages of oxen for mouldboard ploughing, delayed planting of maize is common in Mangwende, Zimbabwe and reduces grain yield by 32%. On-farm experiments over four years tested the possibility of using a ripper ...
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. ...
Soil fertility management effects on maize productivity and grain zinc content in smallholder farming systems of Zimbabwe
Background and aims: Low soil zinc (Zn) threatens crop production and food nutrition in most cereal-based cropping systems in Africa. Agronomic management options that include farmers' locally available organic nutrient ...
