Análise comparativa dos custos de produção entre safrinha e safra milho: um estudo nas principais cidades produtoras do Brasil

Abstract

The second corn crop (off season) has been gaining prominence in the national agricultural scenario, with its average productivity comparable to that of the main crop. Cultivating corn in the second season allows for better crop rotation, contributing to disease, pest, and weed control, as well as soil fertility improvement. Additionally, it enables farmers to diversify the risks associated with agriculture, reducing dependence on a single crop and managing costs more effectively throughout the agricultural year. However, it is important to note that secondseason cultivation still entails risks and requires a more in-depth analysis to demonstrate its viability. In this context, the study conducts a comparative analysis of planting costs between the main and second crops, using data from Conab in the main producing cities of Brazil. Employing a selected descriptive quantitative methodology, the study aims to examine how the production costs of second-season corn behave in different regions of the country, utilizing statistical procedures, comparing total production costs, and processing database information from official sources provided by Conab. Trends in production cost proportions have revealed a gradual convergence over time between second-season corn costs and those of the main season, particularly from 2014 onwards. Analysis of variance (ANOVA) showed statistically significant differences for the CMO and CHA groups, underscoring the need for further investigations to better understand the nature of these differences among the studied groups.
