The word carries two primary, context-dependent meanings: 1. A useful forage plant: In managed agricultural settings, it can be a deliberately planted crop for animal feed. 2. An invasive weed: In the context of cultivated fields (e.g., for corn, cotton, soybeans), it is almost exclusively discussed as a tenacious and undesirable pest. The negative connotation is dominant in modern agricultural usage.
