Abstract
Determinants of adoption decision have been studied by many researchers for a long time. This systematic review applied weight analysis method to summarize and synthesize the most common factors from twenty-one studies that determine the farmers’ adoption decision of improved crop varieties in a regular pattern in Ethiopia. Hence, the result revealed that factors like Access to credit, Participation in social organization, hired labour, Participation in field day, farm income, farm size and extension contact were marked as best determinants. While training, oxen, fertilizer and access to input market were identified as promising determinants. This review recommends that adoption studies are still in need of fully conceptualization of the studies and methodological improvements. Key words: Determinants, adoption, crop-varieties, weight- analysis, Ethiopia.
Highlights
Agriculture is the back bone of Ethiopian economy
This systematic review aimed at: (i) Summarizing the result of many research articles that has been conducted on the determinants or factors that influence the adoption decision of improved crop varieties in the past ten years in Ethiopia. (ii) Synthesizing these incongruent results and sorting factors that influence the adoption decision of improved crop varieties as best determinants, promising determinants and worst determinants (iii) Assessing the existence of universally acceptable effect of explanatory variables across the studies
As a result of reviewing the selected articles conducted on the determinants of adoption decision of improved crop varieties, forty-eight independent variables were identified
Summary
Agriculture is the back bone of Ethiopian economy. It is indispensable for the comprehensive growth through ensuring food security and assuring economic wealth for many of the third developed countries. According to (Macauley and Ramadjita, 2015) and Bihon (2014), absence of suitable and affordable new agricultural technologies, inaccessibility to agricultural technology and low adoption rate toward new agricultural technologies are among the main obstacles of agricultural sector To overcome these obstacles the Ethiopian Government has been allocating substantial resources to research and extension in view of inspiring small-scale farmers to increase their productivity (Bayyisa, 2010).
