摘要
Agriculture provides food for the people and generates hard currency for exporting countries. One of the moving forces is the production of the knowledge and technology required for the sustained growth of the agricultural sector. The relationship between the production of a primary good and the generation of knowledge to produce it was analyzed in leading countries in their respective production. Upon studying the number of publications in scientific journals a general positive correlation is found between national production of diverse crops and the generation of knowledge about each of them. However, in general industrialized countries contributed proportionately more to knowledge generation than to physical crop production and most of their scientific output was published in international journals with higher impact. In contrast, in the group of less industrialized countries production, in general, was proportionately larger in grain than in knowledge, except for certain crops in Brazil, China and India, and most of the knowledge produced was disseminated in journals of lower impact, with the exception of Argentina, which showed an intermediate pattern. In general, the number of published articles is associated positively to the funds assigned to research and development, notably higher in industrialized countries, both in absolute terms and in relation to their gross domestic product. Recognizing the pivotal role of science for agricultural progress will be crucial for emerging economies and should be a central theme in their public policies.
