Estimating consumer willingness to pay for food quality with experimental auctions: the case of yellow versus fortified maize meal in Kenya
Biofortification of maize with provitamin A carotenoids is a new approach to the alleviation of vitamin A deficiencies in Africa. Unfortunately these varieties are yellow or orange, while consumers generally prefer white. ...
Problems and prospects of the Triticale option for Kenya

Ecogeographical distribution of wild, weedy and cultivated Sorghum bicolor (L.) Moench in Kenya: implications for conservation and crop-to-wild gene flow
The potential gene flow between a crop and its wild relatives is largely determined by the overlaps in their ecological and geographical distributions. Ecogeographical databases are therefore indispensable tools for the ...
Wheat Farmers' Seed Management and Varietal Adoption in Kenya
(CIMMYT *Egerton University *KARI, 2002)
Wheat is the second most important crop in Kenya after maize and is becoming an important source of food both for humans and livestock. Despite increasing wheat production, only 50% of domestic consumption requirements are ...
Striga control and improved farm productivity using crop rotation
Crop rotations with crops that are non-hosts of Striga were evaluated to reduce the Striga seed bank in the soil and increase farm productivity. Field experiments were conducted at two sites in western Kenya from 1996 to ...
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 ...
