The increasing Kenyan population demands an increase in maize production if intermittent food deficits have to be averted. Since the introduction of improved maize varieties in mid-1960, the start of Green Revolution period, maize yields increased drastically up to 1970s and started declining from 1980s to-date. The key contributory factors are nutrient mining, sub-optimal input use and insect pest damage. Of the insect pests, stalk borer is of economic importance. Currently, KARI and CIMMYT are developing maize varieties that are tolerant to stalk borer damage. In order to evaluate the potential impact of these interventions economics of stalk borer control at farm level was evaluated. Surveys complemented with on-farm trials were executed in six major maize growing zones of Kenya. Farmers were randomly selected and a sample-frame established after which ...

It first analyses the impact of liberalization on input and output prices, followed by an analysis of farmer practices comparing two major farmer surveys, from 1992 and 2002. The results show that liberalization has had a general positive impact on the evolution of prices, with a decrease of input/output price ratios. However, fluctuations of maize prices has become very high and, combined with a decrease of marketing by the marketing board, has increased the uncertainty in maize production. The liberalization has also resulted in a decrease in extension services. Fortunately, farmers have an increased access to credit services. The combined effect of prices and access to services has resulted in little change in the number of farmers using new maize technologies, in particular improved varieties and fertilizer. The dose of fertilizer per ha has, however, decreased. As a result,...
