Abstract
We evaluated the effect of length of fallow period after application of glyphosate herbicide to kill oats ( Avena sativa L.) planted for grazing. We also evaluated grazing management practices on the subsequent emergence, growth and yield of grain sorghum ( Sorghum bicolor (L.) Moench) planted for grain in a no-till system. Grazing increased soil r esistance to penetration in the top 2 inches by 9% and incr eased availability of NO 3 -N in the top 8 inches of soil significantly as the length of fallow period increased. The number of grain sorghum plants and their growth were reduced significantly when the fallow period was less than 20 days or greater than 40 days. When the fallow period was only 19 days, the NO 3 -N concentration and grain sorghum stand was affected by the amount of oats stubble pr esent. Grain yield was r elated to the number of plants that survived.
