The native forage, false Rhodes grass [Leptochloa crinita (Lag.) P.M. Peterson and N.W. Snow], represents an important component of the arid and semi-arid rangelands of the Americas, due to its large area of distribution and its tolerance to drought and cattle grazing. Precise information on its nutritive value and the factors that influence this trait is relevant for its effective utilization as a forage in arid regions of the world where revegetation with L. crinita is possible. Here, we characterized dry matter (DM) per plant and nutritive value parameters in leaves, stems, and panicles of 21 genetically-diverse L. crinita accessions, in a two-year partially replicated trial. Dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ash, fat, P, and Ca concentrations were determined. Significant (p
