Análise econômica de sistemas de produção agrícola no sudoeste do Paraná

Abstract

This study aimed to evaluate different crop succession and rotation systems involving soybean, corn, common bean, pearl millet, buckwheat, and other species over six years of cultivation. The analysis considered effective operating costs (EOC), gross revenue (GR), gross margin (GM), and operating profit (OP). The experiment was conducted at the Experimental Station of the Federal University of Technology 3 Paraná, Dois Vizinhos campus. To determine the economic indicators, crop yield under different management systems, market prices of grains, input costs, and expenses with outsourced mechanized operations were considered in order to calculate the main profitability indicators. Results indicated that systems using cover crops in the second season had lower EOC, while grain production in both seasons required higher investments but yielded greater economic returns. The S3T13 system, involving rotation between common bean, corn, and soybean, achieved the highest OP, standing out for its productive stability and profitability. It is concluded that crop diversification and proper rotation result in superior agronomic and economic outcomes, being recommended strategies for sustainable and profitable agriculture.
