Agricultural extension service delivery system is a vital component in agricultural development initiatives of any nation. Several extension approaches are used to achieve these initiatives. Globally, many Governments and development partners in rural agricultural development initiatives have gradually transitioned away from total state control of rural community and agricultural extension service delivery into adopting and supporting a more multifaceted system built on holistic participatory approach commonly referred to as Agricultural Value Chain Extension Approach (AVCEA). This AVCEA is relatively new in developing countries, including Kenya, and specifically in Kericho County where exploration on its impact on farm-level technology adoption has yet to be undertaken. The purpose of this study was to investigate the interdependent effects of agro-input node interventions on the adoption of cattle milk production technologies among smallholder farmers in Kericho, Kenya. This study adopted an ex-post-facto research design and systematic random sampling technique to select a sample of 132 farmers who previously exposed to AVCEA. Interviews were conducted for eight (8) dairy production experts and 6 Dairy organization representatives as key informants. The primary data were collected using interview schedules, questionnaires and focus group discussion tools. The data were analyzed for descriptive statistics like frequencies, percentages and inferential statistics like Chi-square tests with the aid of SPSS version 26.0. The results of the study indicated that there was a significant interdependence between some agro-input value chain node interventions and the adoption of cattle milk production technologies. There was also Interdependence between ease of access to farmers ‘groups/cooperative societies and the adoption of cattle milk production technologies by the smallholder farmers. Based on findings of this study, Agricultural experts, stakeholders, and other concerned bodies should focus on developing strategies to strengthen interventions at the agro-input node, particularly by fostering cooperation among smallholder farmers to enhance collective actions.
