A Meta‐Analysis Reveals That the Protective Role of Silicon in Grasses Against Fungal Pathogens Depends on Infection Mechanism

Plant, Cell &Environment, Volume 49, Issue 8, Page 5947-5964, August 2026.
ABSTRACT Pathogen infection drives plant community structure and constrains global agricultural productivity. Silicon (Si) improves resistance to abiotic and herbivory stress, particularly in grasses, but relatively little attention has addressed Si‐mediated resistance to pathogens, nor has it tested how this varies according to the type of plant and ...

Performance, nutrient use, and methanogenesis of Nellore cattle on a continuous grazing system of Urochloa brizantha and fed supplement types varying on protein and energy sources

Livestock Science, 2021
Supplementation of grazing cattle may improve forage utilization, methane emission and efficiency of nutrients use. This study aimed to evaluate the effect of different supllementation strategies on performance, metabolic parameters and methane emission ...

Phytoremediation of soils contaminated with picloram by Urochloa brizantha

Pesquisa Agropecuária Tropical, 2014
Picloram is an herbicide that presents a high persistence in the soil and may severely harm crops in rotation and the environment. The phytoremediation of contaminated areas has been investigated in order to decrease the persistence and environmental impacts of this herbicide.

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 ...

Urochloa brizantha competition on initial growth, physiology, and use of macronutrients in Caryocar brasiliense

Plant Species Biology
Forest recovery using Caryocar brasiliense (pequi) seedlings faces problems related to weed competition. Despite its relevance, weed competition has been little studied, especially in relation to its coexistence with Urochloa brizantha, which is ...

Can Marandu Grass (Urochloa brizantha) Extract Modulate Methanogenesis and Rumen Microbiota?

Agriculture
Urochloa spp. are the most important grasses for ruminants in Brazil and contain secondary metabolites, mainly saponins. Urochloa brizantha extracts (ethanolic EE and hydroalcoholic HE with 3.62 and 5.38 mg protodioscin mL−1, respectively) were developed

Plant growth‐ promoting bacteria inoculation and co‐inoculation effects on Palisade grass (Urochloa brizantha cv. Marandu) in ferralsol in Amazonas State, Brazil

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Deforestation is primarily driven by three main factors the conversion of the Amazon rainforest into pastureland, agriculture, and mining, as well as land invasion. These pastures are mostly degraded, and it is necessary to restore their productive capacity. Microbial inoculants can be used to increase nutrient use efficiency. The objective of

Physiological quality of Urochloa brizantha seeds submitted to priming with calcium salts [PDF]

Pesquisa Agropecuária Tropical, 2019
ABSTRACT Seed priming provides a variety of benefits, including seed invigoration and reduced dormancy. Urochloa brizantha seeds are typically primed with difficult-to-acquire potassium nitrate (KNO3). In this sense, calcium salts stand out as an alternative, but it is important to determine whether they provide the same benefits as potassium nitrate ...
