Abstract:
Water stress significantly limits soybean (Glycine max L.) productivity worldwide. Early water stress detection is crucial for implementing timely irrigation strategies to mitigate its adverse effects. Electronic noses (E-Noses), equipped with sensor arrays that detect volatile organic compounds (VOCs) emitted by plants, offer a non-invasive approach to monitoring plant health. This study proposes using radar chart areas as a novel method to evaluate the sensitivity of e-nose sensors in detecting water stress in soybeans. By converting multivariate sensor responses into radar charts, we quantitatively assess sensor performance and identify the most responsive sensors to water stress-induced VOC changes. The results demonstrate that radar chart areas provide a comprehensive metric for sensor sensitivity, enhancing the effectiveness of e-noses in agricultural applications.
