Forage Responses and Beef Cattle Performance in Silvopasture Systems: A Meta‐Analysis of Tropical and Subtropical Regions of Brazil

Grass and Forage Science, Volume 81, Issue 3, July-September 2026.
ABSTRACT Silvopasture systems integrate tree, forage, and livestock components, offering a sustainable intensification strategy that combines environmental and productive benefits, although shading may impose constraints on forage accumulation. This study aimed to evaluate forage accumulation, nutritive value, and beef cattle performance in pastoral ...

Cover crops and nitrogen rates: Impacts on no‐till corn and soil health in Louisiana

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Use of cover cropping systems to improve soil health is still limited in Louisiana. This study aimed to examine the interaction between cover crops and nitrogen (N) fertilizer rates on crop yield, soil chemical, and biological properties. Winter cover crop treatments, including legumes, a grass and brassica, and a fallow control, were combined

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 ...
