Alfalfa plants can catch water from sprinklers, which is important for efficient watering. Researchers studied how much water alfalfa plants can catch at different growth stages using low-pressure sprinklers. They found that the plants can catch more water as they grow, with the most being caught during the bud stage. The type of sprinkler used also affects how much water the plants can catch. The taller and leafier the plants are, the more water they can catch. This information can help farmers know when and how much to water their alfalfa crops.
