Lucerne, also known as alfalfa, is a perennial legume crop that is known as the "Queen of forage crops" as it is highly nutritious, productive, and tolerant of drought and frost. It is cultivated primarily for hay and can be grown in various climates, with optimal growth occurring in loamy soils with adequate drainage. Lucerne fixes atmospheric nitrogen, is highly palatable and digestible for livestock, and can yield between 35-40 tons per acre in Punjab when harvested up to 6 times per year.
