Avaliação produtiva e econômica da produção de silagens de capim mombaça e sorgo

Abstract

The objective of this study was to compare the production and economic viability of Mombaça grass and sorghum silage, analyzing the productivity of the crops in different plots and the production cost of both. The production, agronomic management and costs of inputs, mechanization and labor were analyzed, considering factors such as climate, soil fertility and productivity. The study was characterized as a descriptive analysis. The methodology for the financial analysis was considered the economic indicators, according to the methodology suggested by the Institute of Agricultural Economics, which considers the following variables: Effective operating cost (COE), total operating cost (COT); total production cost (CTP); gross revenue (RB); operating profit (LO); unit profit (LU); return on investment (ROI); break-even point (PE); return period (payback); projected economic analysis (NPV and IRR). This methodological framework is adapted by several authors in studies of economic viability of forage crops. Mombaça grass silage had a lower production cost and higher return, with a profitability index of 66.04% compared to 31.31% for sorghum silage. The payback period for Mombaça grass silage was significantly shorter at 15.78 months than that for sorghum silage at 33.92 months. The study showed that Mombaça grass has an economic advantage and a quick recovery of the investment, while sorghum, despite its superior nutritional value, requires greater initial capital and a longer return.
