Speaker talking to a group of people in front of a field.

Oklahoma is the nation’s fifth-largest producer of hay, with forage and hay produced on pastureland playing a significant role in the prosperity of farms and ranches involved in livestock production, which generates billions of dollars to the state economy annually. Approximately 20 different grass and legume species are grown for pasture and hay in Oklahoma.


The OSU Extension Forage and Pasture Management program provides timely and relevant resources to assist producers in making the best possible decisions when adjusting for differences in plant species, soil types, precipitation amounts, temperature and similar considerations. You can also access up to date Fact Sheets about Pastures and Forage on the OSU Extension web site.



GrazeOK is a user-friendly electronic version of the Oklahoma grazing stick, which allows fast and proper estimation of stock density, number of pastures, grazing and rest days by simply measuring plant height and canopy cover with a yardstick and inputting them in your phone.
