Levels of nutrients and grain yield of maize intercropped with signalgrass (Brachiaria) in different arrangements of plants [PDF]

Planta Daninha, 2015
Competition between maize and signalgrass can economically cripple the intercropping by the reduced yield of maize and dry matter content of the forage. In seeking to define plant arrangements which make this system more efficient, this research was held

Community grown corn growth with Bidens pilosa and Urochloa brizantha

, 2020
Studies on the competitiveness of weed crops allow us to develop strategies for their management, since they can define the characteristics that give a greater competitive ability to the crops. Thus, the objective of this work was to determine the effects of the competition of brachiaria and blackthorn species and the combination of the two in ...

DRY MATTER AND PROTEIN ACCUMULATION AS A FUNCTION OF NITROGEN FERTILIZATION IN Brachiaria brizantha CV. MARANDU (Urochloa brizantha)

Revista Brasileira de Agropecuária Sustentável, 2022
In Brazil, forage is the main source of nutrients for ruminants, but most production systems are extensive and low amounts of inputs are used to improve soil fertility. This study aimed to evaluate the effect of nitrogen doses on dry matter yield and protein content in leaves, stems and shoots of Brachiaria brizantha cv. Marandu.

Structural and Functional Shifts in Belowground Components Following Grass Invasion in a Tropical Savannah

Journal of Vegetation Science, Volume 37, Issue 2, March/April 2026.
Our study reveals that the belowground component of Cerrado savannahs invaded by Urochloa brizantha is functionally and structurally different from that of non‐invaded areas. Invaded areas were dominated by the invader's fine roots and rhizomes, with reduced bud bank density.
