With the beginning of autumn, the concern in the central areas of Brazil becomes the final period of the rainy season. This change in the precipitation regime directly impacts the second-crop agricultural cultures, such as cotton, beans, and corn. In this crop season, there were rainy periods at the time of sowing these crops, making it impossible or delaying sowing within the ideal window, especially in areas of the states of Goiás and Minas Gerais.
