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.
21 pages, via Online Journal, This paper explores the role of regulation and legislation on influencing the development and diffusion of technologies and methods of crop production. To do this, the change in pesticide registration under European Regulation 1107/2009 ‘Placing Plant Protection Products on the Market’ was followed through the UK’s agricultural system of innovation. Fieldwork included: a series of interviews conducted with scientists, agronomists and industry organisations; a programme of visiting agricultural events; as well as sending an electronic survey to British potato growers. The innovation system is noted to have made the legislation less restrictive than originally proposed. The most notable system response to the legislation is the adjustment of agrochemical company pesticide discovery strategy and their expansion into biologically derived treatments. There have also been other innovation responses: agricultural seed companies have been breeding in pathogen resistance in their cultivars; agricultural consultancies are prepared to recommend pathogen-resistant seeds; scientists are using the change as justification for adopting their solutions; the agricultural levy boards funded research into off-label pesticide uses; and producers, potato growers in particular, have been seeking advice, but not changing their growing practices.

4 pages, Selecting optimal corn and soybean seeding rates are difficult decisions to make. A survey of Ohio and Michigan farm operators finds that, although generally keen to learn from others, they tend to emphasize their own experience over outside information sources. Soybean growers declare university and extension recommendations as more important than do corn growers. In response to direct queries and in free comments, growers place more emphasis on understanding the agronomic and technological problems at hand than on adjusting to the market environment. Given the decision environment, we argue that these responses are reasonable.
