Análise do zoneamento agrícola de risco climático para as culturas anuais no município de Cocal, Piauí

Abstract

The agricultural sector in the Northeast faces several bottlenecks in achieving ranking in production statistics, and one of them is the risk of loss linked to climate conditions. In this study, cassava, corn, and cowpea crops were used, as they are the most cultivated crops in dryland conditions by family farmers in the municipality of Cocal, with the aim of analyzing the Agricultural Zoning of Climatic Risk (ZARC) for these crops. The research was carried out between July and September 2024, with academic research and analysis of the “ZARC-Plantio Certo” application. The inclusion of the application in agriculture allows producers to make appropriate decisions about planting times, outlining fundamental strategies to strengthen their properties. For the municipality of Cocal, cassava cultivation with the lowest climate risk (20%) is recommended in the months of January to March, varying according to soil texture. Regarding short and long cycle bean crops, the most appropriate window for sowing occurs in the months of March and April. Failure to adhere to this guideline may imply an increase in climate risk of 30% to 40%. Sowing of short cycle corn is more suitable for the third ten days of January for medium and clayey textured soils and may extend to the months of February to march. For long cycle crops, it begins in the third ten days of January to the third ten days of February and may have interference or vary depending on the texture of the soil
