Evolução da área plantada, produção e produtividade do milho no município de Porto Nacional, Tocantins, no período de 2015 a 2024

Corn is an important crop for Brazilian agriculture and for the productive dynamics of the state of Tocantins. This study aimed to analyze the evolution of corn planted area, production, and productivity in the municipality of Porto Nacional, Tocantins, Brazil, from 2015 to 2024, identifying the main variations throughout the historical series. This is a descriptive study with a quantitative approach, based on secondary data from the Municipal Agricultural Production (PAM) survey, provided by the Brazilian Institute of Geography and Statistics (IBGE). The indicators analyzed were planted area, production, and corn productivity. The results showed fluctuations throughout the period, particularly a decline in production indicators in 2016 and an expansion in the final years of the series. In 2024, the highest values of the analyzed period were recorded for planted area, at 34,567 hectares; production, at 161,355 metric tons; and productivity, at 4,668 kg/ha. Between 2015 and 2024, planted area increased by 95.7%, production by 109.6%, and productivity by 7.1%. It is concluded that the historical series reveals important changes in the dynamics of corn production in Porto Nacional, particularly the expansion of the analyzed indicators in recent years. However, due to the descriptive nature of the study, causal relationships regarding the observed variations cannot be established.
