Physiological response of marandu grass seeds exposed to NPK fertilizer [PDF]

Ciência Rural, 2019
ABSTRACT: To facilitate seeding process of forage species, a common practice is to mix seeds with fertilizers in monocropping and intercropping or in implementing integrated livestock production systems. However, in prolonged periods of contact, the fertilizer’s salinity and acidity negatively affect the seeds’ physiological quality.

Climate risk and seasonal forage production of Marandu palisadegrass in Brazil [PDF]

Anais da Academia Brasileira de Ciências, 2020
This study aimed to characterize Brachiaria brizantha cv. Marandu seasonal production (seasonality) and its variation (climate risk) yearlong throughout Brazil. Data from weather stations in Brazil (1963-2009), were associated with an empirical herbage accumulation rate (HAR; kg DM ha-1 day-1) model which considers growing degree-days adjusted by a ...

TOLERANCE OF MARANDU GRASS TO EXCESS IRON AND MANGANESE

REVISTA DE AGRICULTURA NEOTROPICAL, 2023
In soaked soils there is an increase in the availability of iron and manganese. Thus, it becomes important to investigate the tolerance levels of plants to excess of these nutrients. The objective was to evaluate the tolerance of Urochloa brizantha cv. Marandu cultivated in nutrient solution with different levels of iron and manganese. The experimental
