Desiccation Periods of Urochloa brizantha ‘Piatã’ Before Sunflower Sowing

Journal of Agricultural Science, 2013
In no-till farming, which integrates crops and livestock, the crop that is sown is often noted for reduced productivity. The aim of this experiment was to study the influence of a desiccation period of Urochloa brizantha ‘Piata’ on sunflower ‘Aguara 4’ development and productivity.

Effect of Season and Nitrogen Fertilization on the Agronomic Traits and Efficiency of Piatã Grass in Brazilian Savanna [PDF]

Agriculture, 2020
The aim of the present study was to evaluate the agronomic traits in the pre- and post-grazing and the nitrogen use efficiency of Piatã grass that was subjected to nitrogen fertilization throughout the seasons of the year. The experiment was performed in a randomized block design with four treatments (0, 150, 300, and 450 kg ha−1 N).

Signal detection and characterisation of a novel drug–drug interaction between methadone and a synthetic cannabinoid receptor agonist

British Journal of Pharmacology, EarlyView.
Background and Purpose Little is known about how synthetic cannabinoid receptor agonist (SCRA) co‐use with other psychoactive substances may exacerbate risk of death. This study aimed to characterise the polypharmacy of deaths where SCRAs were detected at post‐mortem, investigate the cardiotoxicity of SCRAs and probe their inhibition of human ether‐a ...
