fear that if villagers were autonomously to elect contact farmers, they might be wealthy farmers, not representative of the average. On the other hand, if there has been no broad discussions in the village about the selection of the contact farmers, then most farmers may be unaware of who the contact farmers are, and will not know to ask them for advice. The World Bank has utilized this T & V system in Turkey, and in different states in India (these projects have a total cost of $141.5 million, of which the Bank has loaned $70.7 million), and has issued a detailed paper suggesting how to evaluate these projects. Benor reports these projects helped increase yields over 50 percent from 1.3-1.7 tons to 2-3 tons per hectare. It should be mentioned that some writers on extension suggest not trying to reach all farmers. In the Latin-American context, one writer suggests that extension agents concentrate their efforts on medium-sized farmers. The large farmers do not need help, and the small farmers are too numerous and weak for the capacities of existing extension services.2 In India, specialized agencies have been created for specific target groups, the Small Farmer Development Agency (SFDA) and the Marginal Farmers and Agricultural Laborers Development Agency (MFALDA). These agencies help small farmers and landless laborers establish enterprises that need little access to land, such as fruit and vegetable or dairy produc- tion, veterinary services, marketing assistance, etc. Michael Cernea and Benjamin Tepping, A System for Monitoring and Evaluating Agricultural Extension Projects (Washington: World Bank, 1977).
