The present study attempts to identify actual use of agricultural resources in the production of corn in the area of Patos de Minas, Zone of Alto Paranaíba, State of Minas Gerais and analyze the economic efficiency with which these resources are being used. It also attempts to identify the possible changes which can increase this efficiency. The area was selected because of its importance in corn production.
The data were obtained bya survey of a randomly selected sample of 88 farmers.
The data was analyzed by means of a Cobb-Douglas type production function.
The independent variables were; cultivatedarea of corn inhectares, human labor in days; depreciation of imporvements in NCr$ and animal labor in days. The dependent variable was sacks of corn of 60 kg.
At the actual level of resource use, 765,61 sacks of corn were produced utilizing 18, 7 hectares of land, 283,7 days of human labor, NCr$ 51, 70 in depreciation of improvements and 96,7 days of improvements and 96, 7 days of animal labor. The profit was NCr$ 317, 00.
Calculation of the optimum combination of resources with all of the factorsvariable was not possible. Land was fixed at three levels, 10, 18,7 and 27 hectares, Considering land fixed at 18,7 hectares, the following quantities of the other resources were used; 298,3 days of human labor, NCr$ 142,40 indepreci- ation of improvements and 26 days of animal labor. The output would be 756, 1 sacks of corn with a value os NCr$ 1. 554, 70.
The profit of NCr$ 536,50 corresponde to 53 percent of the costs of the factors of production consider d, while in the case of the actual use of resources, the profit represented only 26 percent of the costs.
It was verified thattheprice of animal labor could have been overestimated. Modification of the price of animal labor resulted in a greater use of animal labor, while the quantities of the other resources used were essentially unchanged.
