Abstract

The use of advisory videos is becoming prominent in agricultural extension, particularly for reaching small-scale farmers with timely and targeted information. This study was conducted to test the effectiveness of video-based advisories in enhancing the knowledge of tea smallholders in Sri Lanka, focusing on three key areas: nursery management, foliar fertilizer application, and labour wage issues. According to the farmers’ perspective, some problems were associated with the access to the updated and valid sources of information. A design-based research approach was adopted. The research process comprised three stages: audience analysis, advisory video development, and video evaluation. This study was conducted during the period of December 2024 –March 2025. Based on the audience analysis results, ten short video clips (4– 8 minutes) were developed using documentary and interview-style formats. A pre-test and post-test design was implemented with 30 smallholders, randomly assigned to two groups to assess knowledge levels before and after viewing the videos. Data were analyzed using the paired sample t-test. The results indicated significant knowledge improvement after watching videos across the selected topics (t = 5.19, p < 0.005). Hence, the video-based extension can have a significant impact on the knowledge level improvement of tea smallholders, and it can serve as a valuable supplement to traditional agricultural training. Also, the learning outcomes of the tea smallholders varied significantly with the variations of educational background and digital media literacy. This study recommends further research on long-term knowledge retention, technology access, knowledge improvement, and farmer adoption rates.
