Regrowth age modifies the leaf anatomy of Brachiaria genotypes
Acta Scientiarum: Biological Sciences, 2018 Changes in leaf anatomy were evaluated in genotypes of Brachiaria brizantha, Brachiaria decumbens, Brachiaria ruziziensis and three Brachiaria ruziziensis clones through tissue proportion in internerval and midrib regions at three regrowth ages ...

Upland rice yield as affected by Brachiaria coverage management
Revista Brasileira de Engenharia Agrícola e Ambiental, 2015 An important point in no-tillage system is the time between cover crop glyphosate desiccation and rice sowing. This study aimed to verify the effect of Brachiaria ruziziensis management time before rice sowing on rice

Grass straw mulching to suppress emergence and early growth of weeds [PDF]
Planta Daninha, 2014 Sorghum, pearl millet, and Brachiaria ruziziensis have similar characteristics which have led to their use for mulch formation in no-till systems. This study was carried out to evaluate the potential of these three species as straw suppliers to suppress ...

Genetic variability in Brachiaria ruziziensis for resistance to spittlebugs
Cropp Breeding and Applied Biotechnology, 2010 The aim of this study was to evaluate the resistance of B. ruziziensis clones to the spittlebug species Deois schach and Mahanarva spectabilis. Together with the cultivar Marandu () and the progenies 77s, 85s and 106s as controls, 71 B. ruziziensis clones were evaluated in a randomized block design.

Phenotypic characteristics for discrimination between advanced genotypes of Brachiaria ruziziensis
Genetics and Molecular Research, 2016 The aim of this study was to use multivariate methods and Pearson and partial correlations to disregard phenotypic characteristics that contribute little to differentiation between Brachiaria ruziziensis genotypes. Eighty-one genotypes of B. ruziziensis were assessed in completely randomized blocks with three replications.

Soil water dynamics and yield in maize and Brachiaria ruziziensis intercropping [PDF]
Pesquisa Agropecuária Tropical, 2020 ABSTRACT In intercropping systems, a high plant density can delay the biomass accumulation and affect the water availability to plants. This study aimed to evaluate the soil water dynamics and the crop yield performance in maize and Brachiaria ruziziensis intercropping under different sowing densities of the forage grass.

Nitrogen and Potassium Topdressing in Maize Intercropped with Brachiaria Ruziziensis
Sustainable Agriculture Research, 2015 Maize has been intercropped with different forage species, especially <em>Brachiaria</em> spp., for different purposes and at different times: after maize harvest, as a food source for cattle; and exclusively for the production of straw to maintain a no-tillage system, which is the main purpose of intercropping in western Paraná.
