Alfalfa, scientifically known as Medicago sativa L. , stands as one of the most vital forage crops globally, often referred to as "the queen of forages" due to its exceptional nutritional value and adaptability. This perennial flowering plant in the pea family Fabaceae (legumes) is primarily cultivated for livestock feed, particularly for cattle and horses, but its sprouts are also consumed by humans. Its extensive root system and nitrogen-fixing capabilities contribute significantly to soil health and agricultural sustainability. Known by various names across different regions, such as lucerne in the United Kingdom, Australia, South Africa, and New Zealand, and as Chara, Rajka, or GAD in parts of South Asia, alfalfa's widespread adoption underscores its importance in diverse agricultural systems. The plant's showy, attractive purple flowers, clustered similarly to clover, not only enhance its aesthetic appeal but also play a crucial role in its ecological interac...
