Agriculture in Burkina Faso faces challenges such as low productivity and limited access to information. Survey data from three regions were analysed using descriptive statistics and inferential testing with a confidence level of 95%. SMS-based interventions showed a significant improvement in farmers' knowledge (p < 0.01) compared to voice call-only services, with an average increase of 27% in adoption rates. Mobile technology enhances agricultural extension but SMS outperforms voice calls, particularly in terms of knowledge dissemination and farmer engagement. Implement mixed methods for better impact and consider pilot projects in diverse regions to validate the findings.
