Toward insect resistant maize for the third world
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 ...
Consumer acceptability of yellow maize products in Zimbabwe
This study analyzes consumers’ awareness of and attitudes towards yellow maize products in Zimbabwe and suggests intervention strategies that will ensure increased production and consumption of the crop, which is ...
An appraisal of farmer variety selection in drought prone areas and its implication to breeding for drought tolerance
Maize production and productivity among small scale farmers of southern Africa is limited mainly by drought and low soil fertility. This study aimed at assessing how farmers prioritize selection of varieties for planting ...
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 ...
