Clover is an annual herbaceous plant. Its length is 50-80 cm. It has a deep root system. It goes 8-10 meters deep under suitable conditions. Effective root depth is 120-180 cm. Alfalfa is an important forage plant. It is very resistant to grazing. For this reason, pasture breeding is a plant that mixes with other plants and improves the quality of mer'an. Clover grows in very cold regions such as Alaska and Siberia, as well as the species that grow in the hottest regions. The higher the number of hot days, the higher the number of forms and hence the yield of grass.
