    SACAROSE NA MITIGAÇÃO DOS EFEITOS DO ESTRESSE HÍDRICO NA CULTURA DO MILHO
    (UNIFEV, 2024) Rafael Paixão Alves
    The maize crop (Zea mays L.) cultivation is fundamental for global agriculture, facing significant challenges, among which water deficit stands out. This study aims to analyze alternatives for mitigating this water stress, addressing aspects such as the plant's physiological response, irrigation management and the adoption of sustainable practices. The justification lies in the growing demand for food and the need to increase the efficiency of water use in crops. The methodology involved a literature review and analysis of previous experiments, focusing on corn responses to different water regimes and management strategies, such as drip irrigation and the use of sucrose application. 16 pots of 8.18 dm³ were used, with substrate, which were randomly separated into the following treatments: 4 pots with water stress, 4 pots without water stress, 4 pots with water stress plus application of sucrose and 4 pots without water stress plus application of sucrose. The solution was 1 mol of sugar (320g) diluted in 1 liter of water. The results indicate that the application of efficient irrigation techniques and the use of sucrose increase the production of corn dry mass. The conclusions highlight the importance of implementing appropriate management practices to mitigate the effects of water deficit and ensure the sustainability of corn production in climate change scenarios.
