dc.description.abstractThis 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.

dc.description.resumoEste trabalho tem como objectivo determinar a combinação das hortícolas que maximiza a margem bruta total, para uma unidade média de produção do agricultor no Vale do Infulene. No contexto do presente trabalho o dono da machamba é visto como o tomador de decisões, o gestor da unidade de produção, o qual dispõe de uma porção de terra, capital de operação, emprega basicamente mão de obra contratada e dispõe de água para irrigar as hortícolas. A margem bruta total obtida numa unidade resulta do somatório das margens brutas parciais de cada uma das hortícolas produzidas. Por essa razão, toma-se importante determinar a continuação das hortícolas que maximiza a margem bruta total. Para este trabalho foram utilizados dados primários e dados secundários. Foi realizado um inquérito numa amostra de 75 produtores para colher dados sobre o uso de insumos e força de trabalho, para determinar os coeficientes de produção de cada uma das hortícolas produzidas, a saber: abóbora, alface e couve. Os principais métodos de análise utilizados neste trabalho são: análise descritiva, orçamentos parciais e programação lnear. Após a análise descritiva dos do inquérito, foram determinados os coeficientes técnicos, os quais serviram para determinar os orçamentos parciais e construir a matriz técnica do modelo de programação linear. Os coeficientes da função objectiva são as margens brutas determinadas nos orçamentos parciais. Os produtores de hortícolas do Vale de Infulene também destinam da sua produção para o auto consumo. Por um lado pode ser que seja mais eficiente produzir as culturas que permitem obter maiores margens brutas e adquiri as quantidades de outras hortícolas necessárias para o consumo mercado. Por outro, o agricultor tem que produzir as quantidades mínimas para o auto-consumo. Segundo os orçamentos parciais todas hortícolas apresentam margens brutas positivas, o que significa que era todas elas, o produtor obtém retornos sobre os custos variáveis. Os resultados mostram que o agricultor pode maximizar a margem bruta produzindo apenas a hortícola com a maior margem bruta. Contudo, constata-se que o custo de produção das quantidades necessárias para o auto consumo é menor que o custo de aquisição, por isso deve-se incluir o auto consumo no plano de produção.pt_BR
