摘要: This paper reviews the literature on factors affecting yield and nutritional value of created wheatgrass (Agropyron cristatum,. A. desertorum or A. fragile). The Agropyrons are cool-season perennial bunch grasses that are grown in western United States Canada where annual precipitation ranges from 9 to 18 inches (230 to 460 mm) forage 400 3000 pounds of dry matter per acre (450 3360 kg/ha). Forage production in northern Great Plains is best correlated with April June precipitation whereas area west Rocky Mountains production is best total autumn to spring precipitation.
