Purpose: The study determined (i) the mediation effect of motivation to transfer on the relationship between performance self-efficacy and (a) training design (b) farmer capacity to transfer and (c) training transfer; and (ii) the mediation effect of training design on the relationship between performance self-efficacy and training transfer. Design/Methodology/Approach: A survey of 301 bean seed farmer trainees in South-Central Uganda was conducted, and data was analyzed using partial least squares structural equation modeling. Findings: Motivation to transfer and transfer design partially mediated the hypothesized relationships, with performance self-efficacy as the independent variable, and training design, farmer capacity to transfer, and training transfer as the dependent variables. Practical implications: Pre-training strategies in which trainees with high levels of performance self-efficacy are selected coupled with market opportunities will motivate trainees more leading to enhanced transfer. Originality/Value: The mediation analysis for a specific agricultural training for small-scale farmers has been conducted and the interactions between critical variables that inform practice and science verified. Theoretical implications: The role of motivation to transfer and training design as mediating variables has been confirmed especially for critical pre-training transfer stages for which interventions can be planned.
