Pasture regrowth from the end of grazing around September 10 through mid-October was significantly greater for all stocking rates on rotationally grazed pastures compared to continuously grazed pastures (Figure 26). Fall regrowth was not measured in 1996, but was in each subsequent year with the overall four-year effect being similar to what occurred in 2000 (Figure 27). There was year-to-year variance in fall regrowth response. Stocking rate effect was significant in every year, but had the least impact following the extremely dry conditions of 1999. Grazing method had the greatest effect following the same dry year. Grazing method was not a significant effect in 1997, but was in the following three years. Late summer moisture conditions were very good in 1997 which may have allowed all pastures to regrow optimally.
