Aridification in semi-arid regions is a recurring theme in Intergovernmental Panel on Climate Change (IPCC) reports and has been documented in Northeast Brazil. This study analyzes the spatiotemporal dynamics of aridification in the Lower São Francisco "Territory of Citizenship" (Sergipe...
This study explores the use of hyperspectral imaging (HSI) combined with machine learning to detect physiological alterations in cassava leaves caused by Xanthomonas phaseoli pv. manihotis (Xpm), a bacterial plant disease that causes significant yield losses worldwide. Therefore, the use of ...
Erwinia psidii is an emerging bacterial phytopathogen of increasing concern in South America due to its ability to infect economically important hosts such as guava (Psidium guajava) and eucalyptus (Eucalyptus spp.). First reported in Brazil in the 1980s, affecting guava trees, the path...
Since 2018, outbreaks of typical bacterial blight caused by Xanthomonas have been observed in summer onion crops in central Brazil. To identify the Xanthomonas species involved and evaluate the role of rotation crops (e.g., soybean) and weeds, surveys were conducted at outbreak sites&#x...
Premature leaf yellowing, which is correlated to a decline in flower quality, represents a major challenge to the postharvest handling and commercialization of alstroemeria (Alstroemeria hybrida). Preservative solutions have been used as a strategy to address this problem. However, the results&#x...
Tem por objetivo caracterizar os polos de produção e de produtores de cenoura no Brasil para orientar políticas públicas e pesquisas. Como metodologia analisou os dados do Censo Agropecuário 2017, do IBGE, para mapear o perfil tecnológico regional. Obteve um retrato detalhado do se...
Avalia a biomassa, teor de mucilagem e acúmulo de macronutrientes em Plantago major L. sob doses de vermicomposto e épocas de colheita. Testa 5 doses (0 a 80 t/ha) em 3 épocas (40, 70 e 100 dias) em Latossolo Vermelho. Conclui que as doses de vermicomposto exerc...
Este trabalho objetivou avaliar a estabilidade térmica da matéria orgânica de dois Latossolos de MG. Amostras dos horizontes A e B, sem pré-tratamento, foram aquecidas até 600 °C por Análise Térmica Diferencial (ATD). Os resultados mostraram que o solo gibbsítico oxidou a uma tempe...
Avaliou-se a resistência à termodegradação dos horizontes A e B de dois Latossolos de MG. Em DBC e triplicata, alíquotas de TFSA foram aquecidas em mufla (100 a 500 °C) e o carbono orgânico quantificado por via úmida, ajustando-se curvas sigmoidais. O Latossolo gibbsítico resi...
Abstract: Climate emergency poses an unprecedented challenge to vulnerable populations, threatening above all low- and middle-income communities that depend on agriculture for their livelihoods, such as family farmers. Extreme events such as heat waves, droughts, and extreme rainfall are expected ...
