Studies of improved seed adoption in developing countries almost always draw from household surveys and are premised on the assumption that farmers are able to self-report their use of improved seed varieties. However, recent studies suggest that farmers’ reports of the seed varieties planted, or even whether seed is local or improved, are sometimes inconsistent with the results of DNA fingerprinting of farmers' crops. We use household survey data from Tanzania to test the alignment between farmer-reported and DNA-identified maize seed types planted in fields. In the sample, 70% of maize seed observations are correctly reported as local or improved, while 16% are type I errors (falsely reported as improved) and 14% are type II errors (falsely reported as local). Type I errors are more likely to have been sourced from other farmers, rather than formal channels. An analysis of input use, including seed, fertilizer, and labor allocations, reveals that farmers tend to treat improved maize differently, depending on whether they correctly perceive it as improved. This suggests that errors in farmers' seed type awareness may translate into suboptimal management practices. In econometric analysis, the measured yield benefit of improved seed use is smaller in magnitude with a DNA-derived categorization, as compared with farmer reports. The greatest yield benefit is with correctly identified improved seed. This indicates that investments in farmers' access to information, seed labeling, and seed system oversight are needed to complement investments in seed variety development.
In Mozambique, the legacies of colonial rule, socialism and civil war continue to constrain economic growth and agricultural production. Eighty percent of Mozambique’s labor force derives its livelihood from agriculture, but the nation remains a net food importer. The majority of all farmland is cultivated by smallholders whose fertilizer usage and crop yields are among the lowest in Africa. While Mozambique has experienced reasonable economic growth since the end of its civil war in 1992, it remains poor by almost any measure. In this literature review, we examine the state of agriculture in Mozambique, the country’s political history and post-war recovery, and the current fertilizer market. We find evidence that smallholder access to fertilizer in Mozambique is limited by lack of information, affordability, access to credit, a poor business environment, and limited infrastructure. The data demonstrate that increased investment in infrastructure is an important step to improve input and output market access for smallholders. The main government intervention currently impacting smallholder fertilizer use is the Agricultural Sector Public Expenditure Program (PROAGRI) initiative, however, more data is necessary to assess the impact of its policies and programs.
