Agronomic Traits, Physiological Parameters, Chemical Composition, and In Vitro Digestibility of Urochloa Brizantha Cv. Piatã, Megathyrsus Maximus Cv. Zuri and Megathyrsus Maximus Cv. Tamani in Silvopastoral Systems

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Urochloa species are widely used in silvopastoral systems (SPS), but production losses highlight the need for more productive forages. This study evaluated agronomic, physiological, chemical composition, and in vitro digestibility responses of Urochloa brizantha cv. Piatã and Megathyrsus maximus cvs.
