Maturity Most wheat in Arkansas is double-cropped with soybean. Thus, early wheat harvest is generally desirable to allow for timely planting of soybean. A disadvantage of a very early maturing variety arises if it begins to grow during early warm periods in the spring, making the plants susceptible to late freeze damage. Although earliness is generally preferred, some late season varieties have greater yield potential than early season varieties. However, the yield of a late maturing variety may be reduced because of high temperatures during grain fill. Planting date can have an important impact on the maturity type selected. Generally, an early maturing variety is better adapted to late planting and a late maturing variety is more suitable for early planting.
