Timing is crucial in managing drought stress to save crops, as highlighted in a recent study published in Plant Phenomics. Researchers from the University of Florida Institute of Food and Agricultural Sciences, USDA, and NASA utilized hyperspectral imaging to identify stress in lettuce plants immediately after watering was decreased.

When it comes to drought stress, timing can be the difference between saving a crop and losing it, whether in a greenhouse or in the high-stakes environment of future space missions. In a recent study published in Plant Phenomics, researchers with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), the United States Department of Agriculture (USDA) and NASA used hyperspectral imaging to detect stress in lettuce plants shortly after watering was reduced.
