Associative diazotrophic bacteria and forage legumes sustain brachiariagrass pasture performance through enhanced root traits

Crop Science, Volume 66, Issue 4, July/August 2026.
Abstract Interest in microbial plant growth‐promoting processes, particularly biological nitrogen (N) fixation (BNF), has increased globally as a strategic alternative to mineral N fertilization. Understanding the response of root traits to diverse N sources plays a critical role in unraveling canopy dynamics and improving decision‐making in forage ...

Repeatability, Genetic Variability and Importance of Forage Traits in Ecotypes of Brunswickgrass (Paspalum nicorae Parodi) via BLUP

Plant Breeding, Volume 145, Issue 3, Page 561-574, June 2026.
ABSTRACT This study estimated the repeatability of forage traits in 84 Paspalum nicorae ecotypes using six statistical methods and quantified the minimum number of harvests needed for effective selection. Multivariate analyses based on best linear unbiased prediction (BLUP) values were also performed to assess genetic variability, identify key traits ...

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 ...
