Tolerance to flooding in five Brachiaria brizantha accessions [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2002
Some physiological and morphological responses of five Brachiaria brizantha accessions (BRA000591 cultivar Marandu, BRA003441, BRA002844, BRA004308 and BRA004391) were compared for plants grown in pots under flooding and well-drained conditions for 14 days.

Novel tetronamides derived from mucobromic acid: synthesis, structural elucidation, DFT calculations and phytotoxic activity

open access: yesPest Management Science, Volume 82, Issue 12, Page 11853-11863, December 2026.
The acyclic mucobromic acid, activated by (1S)‐(+)‐10‐camphorsulfonic acid, afforded the chiral compound 1b, precursor for aza‐Michael addition/elimination on the butenolide yielding tetronamides 2b‐7b. Their relative SRSR configuration was confirmed by the spectrometric methods, DFT calculation and statistical methods.

Evaluating seedling traits, maintenance and effective costs to support tropical forest restoration practices

open access: yesEcological Solutions and Evidence, Volume 7, Issue 4, October/December 2026.
Seedling weeding in tropical forest restoration may not be universally needed across all species. Its cost may not be affordable for private landowners. This research shows that all landowners who wish to plant trees on their lands should be encouraged to do so—weeding or no weeding.

Effect of Contrasting Tropical Grazing System Intensification on the Performance of Holstein and Jersey‐Holstein Crossbred (Kiwi Cross) Dairy Cows

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 5, October 2026.
Milk production in Brazil relies on pasture, and intensifying production systems help reduce land use, leading to reduced deforestation and environmental impact. The hypothesis that Jersey crossbred cattle are particularly well suited to grazing systems is also important for Brazilian livestock sustainability.

Soil carbon stock and physical attributes under land‐use chronosequence in the Brazilian Cerrado

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Land‐use changes impact soil physical quality and carbon stocks. Most studies evaluating the conversion of native Brazilian Cerrado to agriculture focus on surface soil layers (up to 40 cm), with fewer examining deeper layers (0–100 cm). This study assessed the impacts of different land‐use systems on soil physical attributes and soil organic ...
