Leaf anatomy of Urochloa brizantha and Urochloa ruziziensis (Poaceae) plants subjected to different fertilization management practices

Agronomy Science and Biotechnology, 2022
Brazilian agribusiness is heavily influenced by beef export. Thus, it is important to evaluate the quality and growth rate of forage species used as cattle food. Given that the structural organization of leaf cells and tissues is directly related to forage-plant growth, we aimed to analyze the foliar anatomy of Urochloa brizantha and U.

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.

In vitro salinity stress tolerance in Urochloa brizantha cultivars

Colloquium Agrariae, 2021
Urochloa brizantha is the main forage grass to raise cattle in Brazil, but salt stress can reduce yield. Physiological and molecular mechanisms of adaptation to salt stress remain poorly understood in this species. The objective of this work was to evaluate the responses of three cultivars of U. brizantha to in vitro salt stress.
