Alocação da terra na produção das principais hortícolas no Vale do Infulene

Abstract

This work aims to determine the combination of vegetables that maximizes the total gross margin, for an average farmer's production unit in the Infulene Valley. In the context of the present work, the owner of the machamba is seen as the decision maker, the manager of the production unit, who has a portion of land, operating capital, basically employs hired labor and has water to irrigate the crops. vegetables. The total gross margin obtained in a unit results from the sum of the partial gross margins of each of the vegetables produced. For that reason, it becomes important to determine the continuation of vegetables that maximizes the total gross margin. For this work, primary and secondary data were used. A survey was carried out on a sample of 75 producers to collect data on the use of inputs and workforce, to determine the production coefficients of each of the vegetables produced, namely: pumpkin, lettuce and cabbage. The main analysis methods used in this work are: descriptive analysis, partial budgets and linear programming. After the descriptive analysis of the survey, the technical coefficients were determined, which served to determine the partial budgets and build the technical matrix of the linear programming model. The objective function coefficients are the gross margins determined in the partial budgets. Infulene Valley vegetable producers also use their production for self-consumption. On the one hand, it may be that it is more efficient to produce crops that allow for higher gross margins and acquire the quantities of other vegetables needed for market consumption. On the other hand, the farmer has to produce the minimum quantities for self-consumption. According to partial budgets, all vegetables have positive gross margins, which means that, in all of them, the producer obtains returns on variable costs. The results show that the farmer can maximize gross margin by producing only the vegetable with the highest gross margin. However, it appears that the cost of producing the quantities needed for self-consumption is lower than the acquisition cost, so self-consumption must be included in the production plan.
