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

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 ...

Agronomic Traits, Physiological Parameters, Chemical Composition, and In Vitro Digestibility of Urochloa Brizantha Cv. Piatã, Megathyrsus Maximus Cv. Zuri and Megathyrsus Maximus Cv. Tamani in Silvopastoral Systems

New Zealand Journal of Agricultural Research
Urochloa species are widely used in silvopastoral systems (SPS), but production losses highlight the need for more productive forages. This study evaluated agronomic, physiological, chemical composition, and in vitro digestibility responses of ...

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 ...

Cover Crops Enhance Aboveground Biomass, Soil Biological Activity and Soil Organic Carbon in Tropical Agroecosystems

Soil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT In tropical agroecosystems, soil organic carbon (SOC) accrual is constrained by rapid organic matter turnover and seasonal water limitation. Cover crops are widely used to improve soil C inputs, but their effects on SOC fractions and soil biological activity can vary according to species composition and management duration.

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

Establishment of Urochloa brizantha cultivars intercropped with different cereal grains

Semina: Ciências Agrárias, 2015
<p>Crop-livestock integration is an alternative method of rehabilitating degraded pastures. The goal of the present study was to evaluate the initial responses of morphostructural characteristics of two different <em>Urochloa brizantha </em>cultivars grown in monocropping or intercropping systems over two agricultural years. <em>

Generalist With a Narrow Niche Breadth: Feeding Ecology and Seed Germination Effectiveness of a Large Canid Within a Silvicultural Matrix

Austral Ecology, Volume 51, Issue 6, June 2026.
Diet: The generalist canid exhibits a narrow niche breadth (0.12), consuming native plants (100% frequency) and animals (85%). Birds dominate animal prey (74%), peaking in the dry season, while Solanaceae plants dominate plant food (100%), peaking in the rainy season.
