The roles of government in the development of agriculture include the following except

The question asks for an option that is NOT a role of government in the development of agriculture. Therefore, we need to look for an option that is not a responsibility of the government in the development of agriculture. The correct option is "training of farmers' children" because it is not a direct role of the government in agriculture development. While the government may provide education and training opportunities for farmers, it is not specifically responsible for the education of their children. The other options listed are all roles that the government can play in promoting and supporting agricultural development.
