AbstractTobosa (Hilaria mutixa [Buckl. ] Benth.) is a coarse, unpalatable grass when it is dormant. It grows on floodplains, which often have a higher production than adjacent, upland areas. Therefore, it is an important resource, often underutilized, in the arid, semidesert region of the southwestern United States. The objective of this study was todetermine if tobosa could be used by weaned calves during the winter-spring period when it is mostly dormant. Herbel found that nitrogen (N) fertilization increased tobosa production on floodplains 2 years during 1957-61. N fertilization increased crude protein of mature tobosa herbage in four of the five years. During 1966-70, Dwyer found that 67 kg/ha of N increased herbage production 2 years. He recommended burning tobosa to remove old growth in early summer, shortly after initiation of new growth. According to Ares, tobosa hay harvested when the plants were green and succulent was readily consumed by cattle. Paulsen showed that cattle grazed dormant tobosa sprayed with molasses much more readily than untreated tobosa.
