Production and consumption traits and the adoption of improved maize varieties: Evidence from seed sample packs and cooking demonstrations

In developing countries, semi-subsistence farmers typically assume dual roles as both consumers and producers of the same crops, which shape their adoption decisions as they balance household food security with market-driven incentives. This study, conducted in eastern Uganda, employs a field experiment with two intervention arms to assess the relative importance of these factors in farmers’ decisions to adopt improved maize seed varieties. The first intervention focuses on production traits, distributing free sample packs of an improved hybrid maize variety to showcase benefits such as higher yields, pest resistance, and drought tolerance. The second intervention emphasizes consumption traits, offering cooking demonstrations and blind taste tests using flour from the same improved maize variety to highlight its taste, texture, and ease of preparation. Our findings reveal that while seed sample packs positively influenced farmers’ perceptions of both production and consumption traits, cooking demonstrations primarily affected perceptions of consumption qualities. We find some evidence that the cooking demonstrations and tasting sessions significantly boosted adoption of the improved maize seed variety promoted by the intervention. However, farmers who received seed sample packs tended to recycle the harvested grain as seed in subsequent seasons, thereby crowding out fresh seed purchases. This practice led to productivity losses, suggesting that the seed trial packs did not translate into lasting improvements in food security or increased market participation.

Brief

Integrating consumer traits is key to increasing uptake of improved crop varieties: Evidence and policy insights from seed sample packs and cooking events in Uganda

 Semi-subsistence farmers in developing countries often play dual roles as both consumers and producers of the same crops. Consequently, decisions regarding crop selection are influenced by a com bination of household consumption needs and market-oriented considerations.  In this policy note, we summarize findings from a field experiment suggesting that integrating con sumption-oriented traits such as taste, color, and ease of cooking alongside production advantages is crucial for driving demand for improved crop varieties.  The field experiment consists of two interventions designed to enhance the adoption of improved maize seed varieties among smallholder farmers in eastern Uganda. The first intervention involves providing farmers with free seed sample packs to plant and directly experience the production related benefits, such as higher yield potential and drought resistance. The second intervention consists of organizing cooking demonstrations and blind tasting sessions to compare maize from improved variety with local varieties, focusing on consumption traits like palatability, texture, and ease of cooking.  We find that the seed sample packs significantly enhance farmers’ perceptions of the seed’s production traits, while the cooking demonstrations improve appreciation for its consumption traits. We also find that the cooking demonstration and tasting session increased the use of fresh Bazooka seed, with some indications that this also led to higher maize productivity. On the other hand, farmers who received the sample packs are more likely to reuse/recycle the grain harvested from the sample pack as seed in the subsequent season, essentially crowding out the demand for fresh/purchased seed. We argue that this may be a rational response in the context of positive transaction costs related to the use of improved seed varieties

Market information and R&D investment under ambiguity: A framed artefactual experiment with plant breeding professionals

Market information and R&D investment under ambiguity: A framed artefactual experiment with plant breeding professionals

Investments in R&D are often made under ambiguity about the potential impacts of various projects. High-quality, systematic market research could help reduce that ambiguity, including in investments in agricultural research-for-development, such as plant breeding. Using an online framed artefactual experiment with a diverse sample of breeding experts working in various disciplines across the world, we ask how market information and information quality influences breeding experts’ investments in prospects with ambiguous returns, and how the quality and source of information affect willingness to pay for market information. We find that providing market information leads participants to make more prioritized (rather than diversified) decisions. However, participants do not consider differences in information quality, instead over extrapolating from noisy and biased information signals. Finally, while most participants are willing to use experimental funds to purchase market information, around half prefer lower quality information even if higher quality information is available at the same price. We conclude that prioritizing R&D projects with greater impact opportunities will require better awareness among decision-makers of quality issues in various types of market research.
