Efeito da deriva de glifosato em capim marandu

Semina: Ciências Agrárias, 2021
A deriva de glifosato em plantas não resistentes à molécula do herbicida pode resultar em estímulo a determinadas características biológicas, caracterizando o fenômeno hormese. Com base nisso, avaliaram-se características produtivas e químico-bromatológicas em capim Marandu, simulando efeito de deriva, com doses subletais do herbicida glifosato.

Soil Phosphorus Fractions: Effects of Silicate Amendments and Phosphorus Sources in Brazilian Tropical Soils

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.
ABSTRACT This study evaluated the effects of alternative phosphorus (P) sources and soil pH amendments on P fractions and soil chemical properties in two contrasting Brazilian tropical soils. A greenhouse experiment was conducted using a sandy Arenosol and a clayey Ferralsol treated with triple superphosphate (TSP), reactive phosphate (RP), or ...

Integrated triple cropping enhances soybean productivity

Crop Science, Volume 65, Issue 5, September/October 2025.
Abstract Using soil cover residues from previous crops through integrated systems has proven effective in driving changes in soil properties with nutrient cycling, promoting higher grain production. However, there is still a need to investigate the changes that different cultivation arrangements of these management systems can influence on soybean ...

Decomposition of straw resulting from different strategies of recovery of degraded pastures using an integrated crop-livestock system

Semina: Ciências Agrárias, 2018
Several strategies have been used to improve soil fertility using integrated crop-livestock (ICL) systems, and the harvest of the accompanying crop used for silage may have several benefits to the soil depending on the quantity and quality of the ...

Growth of marandu palisadegrass subjected to strategies of intermittent stocking Crescimento do capim-marandu submetido à estratégias de lotação intermitente

Scientia Agricola, 2009
Grazing strategies alter sward leaf area patterns of growth, affecting herbage accumulation and utilisation. The objective of this experiment was to evaluate the growth of marandu palisadegrass (Brachiaria brizantha cv. Marandu) swards subjected to strategies of intermittent stocking.

Structural and productive responses of signalgrass and its association with leaf area index and light interception under silvopastoral or monoculture systems

Agrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Silvopastoral systems (SPSs) have emerged as one of the most prominent alternatives for grassland recovery. We evaluated the structural and productive responses of signalgrass [Urochloa decumbens (Stapf.) R. D. Webster] and its association with leaf area index (LAI) and light interception (LI) measured with different equipment across different
