Brachiaria ruziziensis and herbicide on the yield of upland rice [PDF]

Planta Daninha, 2012
The correct management of cover crops in no-tillage aims to obtain greater benefits with its introduction in agricultural systems. The use of forage species such as Brachiaria, due to the large amount of biomass and for persisting longer on the ground, has become a good option.

Avaliação do glyphosate e paraquat no manejo da Brachiaria ruziziensis [PDF]

Revista Brasileira de Herbicidas, 2013
O objetivo deste trabalho foi o de avaliar o efeito de doses do paraquat e do glyphosate na dessecação da forrageira Brachiaria ruziziensis. O delineamento experimental foi de blocos casualizados com quatro repetições. As doses do do glyphosate foram 0, 90, 180, 360, 720 e 1440 g ha-1 e do paraquat foram 0, 50, 100, 200, 400 e 800 g ha-1.

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.

ESTABLISHMENT OF THE BRACHIARIA RUZIZIENSIS X BRACHIARIA BRIZANTHA HYBRID UNDER HUMID TROPICAL CONDITIONS

Revista de Investigaciones Veterinarias del Perú, 2007
The hybrid Brachiaria ruziziensis x Brachiaria brizantha (pasto Mulato) has been released as a highly productive tropical forage. This new option is being tested at Pucallpa in a field trial under a combination of NP fertilizer rates (0, 75 y 150 kg/ha/year of N and 0, 25 y 50 kg/ha/year of P).

Meiotic behavior in apomictic Brachiaria ruziziensis × B. brizantha (Poaceae) progenies [PDF]

Scientia Agricola, 2012
Hybrids combining desirable traits from divergent parents are the main objective of some Brachiaria (Syn. Urochloa P. Beauv.) breeding programs. There is great interest in the development of apomictic hybrid cultivars that combine desirable genes such as resistance to spittlebugs, high nutritive value, and tolerance to acid soils.

Nitrogen dynamics as a function of pH in soil cultivated with brachiarias

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Brachiaria production is an important segment in Brazil's agriculture, used as a forage or animal feed. Studying the influence of Brachiaria sp. on soil nitrogen (N) dynamics under different soil pH and amendment conditions is a critical research need.

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.
