Forage Biomass and Chemical Composition of Buffelgrass Genotypes in the Semi‐Arid Region of Brazil

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Forage improvement in semi‐arid regions requires the identification of genotypes capable of maintaining productivity under climatic variability and chronic water scarcity. This study evaluated six buffelgrass (Cenchrus ciliaris L.) genotypes over two production years in northern Minas Gerais, Brazil, to characterize their agronomic, morphological, and ...

ADUBAÇÃO POTÁSSICA DE CULTIVARES DE Megathyrsus maximus

Nativa
O potássio é o segundo macronutriente mais absorvido pelas plantas, podendo limitar a resposta da produção de forrageiras, principalmente as de maior exigência nutricional. O objetivo foi identificar a dose de potássio mais adequada para o desenvolvimento de cultivares de Megathyrsus maximus (Zuri, Tamani, Massai e Mombaça). O trabalho foi realizado na

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

New 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.

Performance of Beef Cattle Under Grazing as Affected by Urochloa decumbens Cultivars

Grass and Forage Science, Volume 81, Issue 2, April-June 2026.
ABSTRACT Testing animal performance under grazing is fundamental to determine the potential of recently released, high‐yielding Urochloa decumbens hybrids. The objective was to evaluate the weight gain of young bulls grazing on pastures of U. decumbens cultivars Basilisk, BRS Carinás, and BRS Poraitê, as well as to assess the nutritive value and plant ...

Different Grazing Frequencies Modify the Structure, Production, and Nutritional Value of ‘Zuri’ Guineagrass in the Brazilian Cerrado

Grass and Forage Science, Volume 81, Issue 2, April-June 2026.
ABSTRACT The increasing climate variability in tropical regions demands management goals that allow for shorter rest periods without compromising pasture persistence. The objective of this study was to evaluate the effects of four pre‐grazing light interception (LI) levels on the structural, productive, and nutritional responses of ‘Zuri’ guinea grass ...
