Risco climático para o cultivo do algodoeiro na região nordeste do Brasil

Abstract: Médias semanais de radiação solar, precipitação pluviométrica, evapotranspiração e temperatura do ar foram utilizadas na delimitação das áreas da região Nordeste do Brasil com menor risco climático para o cultivo do algodão. Para cultivos irrigados, o potencial de rendimento da cultura foi avaliado pelo índice acumulado de crescimento (IAC). Para cultivo de sequeiro, o risco climático foi determinado pelo déficit potencial de água (DPA). Para cultivos irrigados, o menor risco de queda de produtividade ocorre q… Show more

“…2021 explained 95% of the variability in the influence of climatic variables on cotton yield according to AIC value, that is, a strong to very strong correlation. For Azevedo & Silva (2007), the ideal mean air temperature range for satisfactory cotton yields is between 20 and 30 °C. Bibi et al (2008) reported that cotton plants are expected to have a high photosynthetic rate at 32 °C, but net photosynthetic rate starts to decrease from 22 °C.…”
