Echinochloa frumentacea, commonly known as barnyard grass, is a species of grass native to tropical and subtropical regions. It is often found in wet, disturbed areas and is known for its rapid growth and ability to thrive in various soil types. This grass can reach heights of up to 1 meter and produces small, spike-like flower clusters. Barnyard grass is considered a valuable forage crop in some regions, providing food for livestock. However, it can also be a troublesome weed in agricultural fields, particularly in rice and maize cultivation, where it competes with crops for nutrients and water.
