Abstract

The environmental changes promote the need to increase crop productivity to meet the global demand for food has been growing. Soybean (Glycine max) plays a crucial role in this regard, both for human and animal consumption. Melatonin (MEL), a bioregulator, has demonstrated efficacy in mitigating the effects of stress, such as those caused by abiotic factors, by boosting the antioxidant system of plants. Under field cultivation conditions, an experimental area at Texas Tech University with a semi-arid climate and high average temperatures will be investigate the application of Melatonin in plants of six different soybean genotypes with resistance to water deficit. The following treatments will be tested: 1) No melatonin (control); 2) With melatonin application (100µMol), under two irrigation regimes, 80% evapotranspiration replacement and 30% replacement. Biochemical and physiological parameters, such as the number of flowers and pods, will be evaluated. The evaluation of the number of flowers and pods will be done using an electronic device with a camera, associated with artificial intelligence that will count and detect soybean pods and flowers. The expectation is that this advanced phenotyping tool will provide insight into counting reproductive structures in different soybean strains with and without Melatonin application, promoting more sustainable agricultural practices.
