White clover is undersown in the spring with wheat, barley and peas. Irrigation is used in order to achieve a heavy flowering in the white clover crop over one month. Three barley crops must be grown successively in some paddocks to eliminate yarrow. Lupins, peas and soybeans are alternative legumes to white clover, but white clover is still the preferred legume to grow, especially with new cultivars becoming available.
