Análise de variáveis de produção do milho no município de Boa Vista/PB
This study analyzes the dynamics of corn production in the municipality of Boa Vista – PB between 2004 and 2023, based on data from the Municipal Agricultural Production (IBGE). Five variables were evaluated: planted area, harvested area, volume produced, average yield, and production value. The data were organized into graphs and subjected to Principal Component Analysis (ACP) using the R software. The results showed high interannual variability in all variables, without a defined linear trend of growth or reduction. A recurring discrepancy was observed between planted area and harvested area, in addition to the occurrence of years with total crop failure, strongly influenced by the rainfall irregularity typical of the semi-arid Northeast region. Production and economic value showed punctual peaks, especially in 2008 and 2022, but maintained unstable behavior throughout the historical series. ACP explained 89.4% of the total variance in the first two components, revealing a strong association between average yield, quantity produced, and value of production, while area expansion did not always result in higher productivity. It is concluded that corn production in Boa Vista is extensive, highly vulnerable to climate change, and faces technological limitations, reinforcing the need for adaptive strategies to increase regional resilience.
