Evaluation of sulfur source and dose on the nutritional state and production of piatã forage

open access: yesSemina: Ciências Agrárias, 2019
Sulfur deficiency in soils has become a worldwide concern for agricultural production. This study aimed to evaluate the concequence of variable sulfur source and dosing on the nutritional status and production of Piatã forage in a dystrophic Ultisol. The experiment was arranged in a completely randomized block design with four replications.

Effect of nitrogen fertilization on structure and tillering dynamics of Piata palisade grass during the deferment period

open access: yesSemina: Ciências Agrárias, 2019
Nitrogen fertilization can increase the appearance of new tillers, which can improve the structure of deferred sward, since the deferral period is not long.

A Green Sample Preparation Procedure for Determining Proline in Honey and Wine by Visible Molecular Absorption Spectrophotometry After Microwave‐Assisted Derivatization

open access: yesChemistrySelect, Volume 11, Issue 38, 13 October 2026.
A green, simple, and rapid method quantifies proline in wine and honey. Microwave‐assisted derivatization and ultrasonic cooling drastically reduced reaction and cooling times. The validated spectrophotometric method shows high accuracy (95.7%–109.4% recovery) and is an eco‐friendly alternative, confirmed by the AGREEPrep (Analytical GReenness metric ...

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 ...

Production and nutrition rates of piatã grass and hybrid sorghum at different cutting ages - doi: 10.4025/actascianimsci.v35i3.18016

open access: yesActa Scientiarum: Animal Sciences, 2013
The influence of cutting age on yield and nutrition rates of piatã grass (Brachiaria brizantha cv. BRS Piatã) and hybrid sorghum (Sorghum spp. cv. BRS 801) under an integrated crop-livestock system was evaluated. The trial was carried out at the Embrapa

Evaluation the physiological quality of Brachiaria brizantha cv. BRS 'Piatã' seeds

open access: yesBioscience Journal, 2017
In a quality control program, seed vigor evaluation is of fundamental importance for the success of the program. The objective of this project was to evaluate the efficiency of several vigor tests to evaluate the physiological quality of Brachiaria brizantha cv. 'BRS Piatã' seed lots and to preview seedling emergence in the field.

Two new species of Calea ser. Multiplinerviae (Asteraceae: Neurolaeneae) from Brazil

open access: yesNordic Journal of Botany, Volume 2026, Issue 9, September 2026.
Detailed studies of specimens from Rondônia and Mato Grosso do Sul showed that two new species have been misidentified: Calea micropappa resembles Calea pilosa, but differs by leaf apex obtuse to acuminate (versus acute), paleae present (versus paleae absent), disc corolla lobes 1.2–1.3 mm long (versus 0.7–0.8 mm), and pappus scales 0.1–0.25 mm long ...

Cover Picture and Issue Information

open access: yesEcological Solutions and Evidence, Volume 7, Issue 4, October–December 2026.
Cover image: Moltrecht’s treefrog (Zhangixalus moltrechti) is a treefrog endemic to Taiwan, characterized by its jade green coloration and vivid orange patches on the inner surfaces of its hind limbs. Although this beautiful species is widespread and abundant throughout Taiwan, our findings reveal that its low‐elevation populations may be particularly ...
