During 2 years we harvested orchardgrass seed on the culms at different stages of maturity and cured it by two methods, viz., in windrows in the field and in a crop dryer at 35C. We used measurements of 1,000‐seed weight to determine if seeds continued to increase in weight after cutting while curing in the windrow. Weight of 1,000 seeds did not increase while curing in the windrow. Continued respiratory activity in the windrow before the seeds became dry may have caused loss of dry matter. Windrow‐cured seeds were superior in germination to dryer‐cured seeds at all stages of maturity.
