Climatic variability in the production of corn, wheat and soybeans

Abstract

This study aimed to analyze how climatic elements affect the production of corn, wheat, and soybeans in the Northwest Mesoregion of Rio Grande do Sul, Brazil. To achieve this, three econometric models were estimated using temperature and precipitation variables to verify their impact on the production of these crops during the period from 2010 to 2019. The results showed that rainfall positively affected the production of all three crops. Maximum temperature negatively impacted the cultivation of corn and soybeans and positively affected wheat, while minimum temperature, dew point temperature, and wind speed negatively impacted the cultivation of all three crops.
