Summary of Methods: Tobosa (Hilaria mutica) was seasonally grazed with cattle in New Mexico, under continuous stocking treatments in 1980 and 1981. Grazing strategies did not influence the proportion of green tobosa within the standing crop. However, flexible rotation produced a more uniform use of green tobosa within the cell, when compared to grazing with fixed intervals between rotations. In this study, flexible rotation of cattle among paddocks, based on a 30-35% reduction of tobosa standing crop height, reduced gray tobosa within the standing crop more than with the continuous stocking treatment. Total heifer liveweight gain per ha in 1980 and 1981 was reduced by 43 and 24%, respectively, under continuos stocking compared to rotationally grazed pastures.

Annotation: Low-density (.33 to .38 au/ha) continuous stocking was conducted in a 33.6-ha paddock while a 34.7-ha cell, subdivided into 10 smaller paddocks, was managed under high density (2.0 to 5.7 au/ha) stocking. Plots excluded from cattle grazing were located in a paddock which lay between the 2 grazed areas.
