Using oral communication instructions to improve marketing and financial management skills of sweet potato farmers

PurposeThe aim of this study was to determine the impact of oral communication in improving the marketing and financial management skills of sweet potato farmers.Design/methodology/approachThe study used a quasi-experimental design with a pre- and post-test approach. The sample was 540 sweet potato farmers that were randomly assigned to training (n = 270) and no-training groups (n = 270) with analysis of covariance (ANCOVA) as the method of data analysis. While the training group received oral training sessions for three farming seasons beginning in 2019, 2020 and 2021, the no-training group did not receive any intervention.FindingsBefore the training sessions, all the sweet potato farmers scored low on marketing skills like advertising, sales promotion and sales forecasting. Both groups also scored low on financial management skills like budgeting, investments, saving and controlling expenditures. Their annual income level was also low and both groups did not significantly differ. However, after the training and during the follow-up evaluation, the participants in the training group reported a significant improvement in their marketing skills and financial management skills. There was also an improvement in their income level from $238 (N109,480) at baseline to $523 (N240,580) after the training and $782 (N359,720) after the follow-up evaluation. On the other hand, the no-training group reported a staggered fluctuation in their income of $241 (N110,860) at baseline, $371(N170,660) during post-training evaluation and $214 (N98,440) at follow-up assessment.Research limitations/implicationsThe first limitation is that the study examined only one crop. There is a need to pay attention to farmers of other crops for better understanding. Another limitation of the study is that the researchers examined only oral communication. There is a need to compare more than one training to understand which is more effective. Finally, the current study did not consider the moderating effect of other factors like the source of labour and expenses.Originality/valueThis study has shown that oral communication is an effective tool for promoting the acquisition of marketing and financial management skills and enhancing agribusiness.
