| In this paper the conceptual framework of individual farmers' adoption decisions of new agricultural technologies is used to identify factors that influence adoption modified fanya juu terraces in semi-arid eastern Kenya. The adoption decision model was specified using farm and farmers' characteristics and technology characteristics though likely to influence farmers' adoption behaviour. To test intensity of adoption a Torbit model was specified and estimated. Results of logit regression analysis reveal that access to markets, education, costs, technology attributes, labour, credit and risk preferences significantly influenced adoption decisions. Results from the estimated intensity of adoption model (tobit) show that variation in the proportion of land... |

| The development and promotion of improved crop varieties as well as efficient seed production, distribution, and marketing systems have contributed significantly to increased agricultural production and food security in Kenya. However, these impacts have not been replicated in the semi-arid midlands due to climatic, soil, and institutional factors. Following the liberalization of agriculture in the late 1980s, there has been greater participation of the private sector, non-governmental organizations, and voluntary agencies in the area. This study examined the extent to which these developments affected farmers’ access to dryland crops. The study found that the low quantity of seed traded, high cost of production, and high seed supply prices constrained the... |

| Lack of access to nutritious food is an underlying and major cause of child mortality in Africa. Improving the nutritional quality of food crops, through biofortification, would be a useful complementary strategy to other agricultural and public health interventions. Quality Protein Maize (QPM) varieties have been developed through biofortification. Consumption of these varieties leads to greater protein utilisation in adults and children. In Kenya three QPM varieties have been released. In Central Kenya, particularly Kirinyaga district, farmers have come together through Innovation Platform for Technology Adoption ( IPTA) with the aim of production, value addition and marketing of QPM based products. These groups require information on the potential... |

| Insect Resistant Maize for Africa Project (IRMA) aims at developing and deploying insect resistant maize varieties to reduce grain losses due to insect pests. As part of incorporating farmer’s perceptions and improving the adoption of the developed varieties, participatory approaches are adopted. The paper analysis farmer’s preferences of maize germplasm developed through conventional breeding. The paper uses data collected from evaluations conducted at the end of 2006 April and October rains. Nine stem borer resistant maize varieties were evaluated alongside six commercial checks in the moist transitional zones (East and West) at vegetative and harvest stage, while in the dry transitional zone and dry mid altitude zones, 6 new varieties were evaluated... |
