12 pages., Purpose
Pervasive use of poor quality seed remains an important reason for low yields throughout the developing world. We explore ways to increase the quality of the local stock of seed tubers among a sample of Ugandan potato farmers.
Design/methodology/approach: Using videos, we provide agricultural extension information on (i) how to select the best seed tubers and (ii) how to properly handle and store seed tubers until the next planting season. The relative effectiveness of the information interventions is tested using an individually randomized controlled trial where we model spillovers using a randomization-based framework for estimating causal effects under interference between units.
Findings: Especially the video on seed selection translated into increased awareness and adoption of recommended practices, increased probability of using improved inputs, as well as higher consumption.
Practical implications: Interventions aimed at improving seed quality are important in the absence of access to high-quality seed. Video messages are becoming increasingly useful as a complementary tool in agricultural extension.
Theoretical implications: Randomization-based inference can be used to take into account spillover effects in the analysis rather than the design phase of an experiment.
Originality/value: This is the first study to address seed quality of potato tubers in a real-world setting using videos.
9 pages., Extension plays an essential role in serving local communities. How it can support farmers during the pandemic is a novel phenomenon that necessitates careful analysis. Drawing from a survey responded by 313 farmers across Hawai'i in late April 2020, this study assesses how farmers feel Extension can support them best during the pandemic. Farmers identified five areas of needs: community engagement and networking, information sharing and education, funding, research, and local sustainability. Discussion regarding the role of Extension support during the pandemic is offered.
