Summary of Methods: Holt et al. initiated grazing in newly seeded Russian wildrye (Elymus junceus) pastures in May, June, and August to determine if delaying grazing would enhance beef and forage production in subsequent growing seasons. Delaying grazing did not effect forage production in the establishment year but enhanced forage production in the second growing season, the greatest production occurring in plots that were delayed until August. Beef production was greatest in the first and second season when grazing was delayed until June during the year of establishment. Therefore the authors conclude that delaying grazing until June will be the most beneficial management practice for livestock producers grazing cattle on newly seeded Russian wildrye pastures in the northern Great Plains.

Annotation: The three grazing treatments in 1981 were: grazing to commence May 1; July 15 (early flower); and August 1 (mature seed). Three yearling Hereford steers (275 kg) were used to graze each paddock each year. In 1981, a put-and-take system was used for the May treatment but other pastures were grazed continuously. From 1981 to 1984, all pastures were grazed continuously from the same date in early May (when 10-cm of forage was available). Animals were removed when grass was grazed to 3-cm.
