Since the beginning of 1970’s, more than 40 improved maize varieties have been released and disseminated to maize potential areas in Ethiopia. Using cross-sectional survey data collected in 2011 from 39 districts in five Regional States, this paper examines smallholder farmers’ knowledge,...

Zambia’s maize seed industry is one of the strongest in the region, and smallholder farmers grow numerous varieties, with no single variety dominating more than a small share of maize area. Yet, the foremost consumer (purchaser) of maize seed over the past decade has been the Government of...

This paper assesses the feasibility of the maize storage structures used in Kenya. Maize is the most important staple crop, but produced seasonally, and consumed continuously at farm level, hence the need for on-farm storage. However, heavy post harvest losses occur mainly during harvesting and...

This paper establishes level of up-take of the business opportunities provided by the metal silos technology among the artisans who were trained on how to make metal silos. It also assesses the factors that determine the practice of the metal silo business among the trained artisans. A third of...
