Abstract
In New England, frequent rainfall, and prolonged high humidity are common during the period of wheat ripening. From the time of physiological maturity of the grain to acceptable storage moisture, the quality of the wheat can decline considerably due to these fluctuating temperatures and moisture conditions. Delays in harvesting may not only result in quality losses but reductions in yield due to lodging, shattering, or hail damage (Farrer, et al 2006). Baking quality of wheat suffers when high levels of the enzyme alpha amylase are present in the grain. This enzyme, which breaks starch down into sugars, is present when the grain begins to germinate. Pre-harvest sprouting occurs in the field if there is a delay in harvest during periods of high humidity or frequent rainfall. The objective of this research was to determine if timing of harvest affects yield and quality parameters of winter wheat.
