- 21 pages, Despite decades of investment in agricultural extension, technology adoption among farmers and agricultural productivity growth in Sub-Saharan Africa remain slow. Among other shortcomings, extension systems often make recommendations that do not account for price risk or spatial heterogeneity in farmers' growing conditions. However, little is known about the effectiveness of extension approaches for nutrient management that consider these issues. We analyze the impact of farmers' access to site-specific nutrient management recommendations and to information on expected returns, provided through a digital decision support tool, for maize production. We implement a randomized controlled trial among smallholders in the maize belt of northern Nigeria. We use three waves of annual panel data to estimate immediate and longer term effects of two different extension treatments: site-specific recommendations with and without complementary information about variability in output prices and expected returns. We find that site-specific nutrient management recommendations improve fertilizer management practices and maize yields but do not necessarily increase fertilizer use. In addition, we find that recommendations that are accompanied by additional information about variability in expected returns induce larger fertilizer investments that persist beyond the first year. However, the magnitudes of these effects are small: we find only incremental increases in investments and net revenues over two treatment years.

- 8 pages, Does it matter whether farmers receive advice on pest management strategies from public or from private (pesticide company affiliated) extension services? We use survey data from 733 Swiss fruit growers who are currently contending with an infestation by an invasive pest, the fruit fly Drosophila Suzukii. We find that farmers who are advised by public extension services are more likely (+9–10%) to use preventive measures (e.g. nets) while farmers who are advised by private extension services are more likely (+8–9%) to use synthetic insecticides. These results are robust to the inclusion of various covariates, ways to cluster standard errors, and inverse probability weighting. We also show that our results are unlikely to be driven by omitted variable bias. Our findings have implications for the current debates on both the ongoing privatization of agricultural extension and concerns regarding negative environmental and health externalities of pesticide use.

- James F. Evans Collection, Washington, D.C. : United States Department of Agriculture, 1926. 20 p. (Department Bulletin no. 1384), With a background of 10 years of cooperative extension work under the Smith-Lever Act, extension administrators and supervisors everywhere are seeking definite information upon which to base decisions affecting the future conduct of the work. Facts rather than opinions are needed. The field study reported in this bulletin was made by the Office of Cooperative Extension Work, in cooperation with the State extension services of Iowa, New York, Colorado, and California. Considerable light is thrown upon concrete problems concerning which extension leaders have long desired reliable information. The determination, in any adequate degree, of the results of extension teaching is a most complex matter. Only some of the most obvious results are here shown. It is hoped the present study mat be the basis for more comprehensive studies in the future. (original)
