Abstract

The objective of the present study was to determine the combination of enterprises to maximize the income of agricultural activities of small landowners in the municipality of Nova Resende , Minas Gerais. The data are from the ProjecTMG-II and concern to the 1980/81 agricultural year . Forty-seven properties were studied, subdivided in four strata according to the area. The linear programming was the research model. Three situations were studied: present situation; planning situation by linear programining which was the decision model; and sensitivity of results to land changes. The results obtained for the planning situation as compared to those for the present situation have shown: a) Objective function - there was a small increase in the objective function for the strata I and II, and there was a high increase for the stratum III; the objective function for the planning situation and the present situation was the same in the stratum IV; this fact shows a correct allocation of resources. b) Constraint resources - the available land was the limiting factor to increase farmer's income in the strata I, III and IV; labor was the restrictive factor to stratum II, and invested capital (available building) was the limiting factor to increase income in the strata I, II and IV. Seasonal labor was not eliminated by the new combination of enterprises. c) Decision variables - most of the production of rice were to self-consumption. The production of coffee was almost totally directed to commercialization. The sensitivity of results to land changes for strata III and IV showed an increase in the objective function; in this case, labor in the second period (November-December), was the limiting factor. The general conclusion is that land and invested capital were the main limiting factors to increase the landowers' income.
