Determinants of adoption and intensity of improved haricot bean (Phaseolus vulgaris L.) varieties: A Socio-agronomic study from southern Ethiopia

Abstract

The Haricot bean (Phaseolus vulgaris L.) is an important legume crop in Ethiopia, serving as the main cash crop and the least expensive protein source for farmers in many of the lowlands and midlands of the country. This study examines the factors that influence the adoption and intensity of improved haricot bean varieties and associated agronomic techniques in the study area. To choose four rural kebeles (purposive sampling) and 100 (technology user) respondents (systematic random sample), a two-stage selection approach was used. In addition, focus group discussions and key informant interviews were held. The findings of the Tobit econometric model revealed that a wide range of factors had varying effects on adopting better haricot bean production practices. The adoption and intensity of improved haricot bean varieties and related agronomic practices were positively and significantly influenced by the gender of the head of the household, attendance at improved training in haricot bean production, field day programs, demonstrations, access to improved seed credit, and membership in a seed multiplication group, while the market distance was negatively influenced. When evaluating and choosing improved haricot bean varieties, farmers in the study area gave high yield, market demand and price advantage, maturity time, grain color, grain size, disease resistance, and storage priority. The Nasir cultivar comes first based on these criteria, followed by the Dimtu cultivar. Furthermore, fewer farmers in the study area applied fertilizer and seed at rates than advised by research and extension. Lack of extension assistance, high fertilizer costs, and lack of funds contributed to farmers' departure from advised packaging practices. To enhance the adoption of improved cultivars, it is suggested that the promotion of improved haricot bean cultivars, as well as improved farmers' access to extension services and timely market information, be emphasized.
