The quality of planting material plays a key role in the sustainability and profitability of cassava cultivation. This study evaluated how different planting materials and supplemental irrigation affect cassava growth, yield, and the quality of harvested cuttings. The experiment took place a...
ABSTRACT - Providing diets with high roughage in the first days of confinement is the common way of adapting beef cattle to intensive production. However, it is possible to offer the final finishing diet from the first day of adaptation. Our objective was to compare a...
The açaí palm (Euterpe oleracea) is a key economic resource in the Amazon region. Despite this, studies on its floral visitors in Amazonas state remains scarce, outdated, lack species identifications and inferences about their role as pollinators. This study aimed to identify the f...
The Amazon rainforest harbors a stock of naturally fallen trees whose rational use is limited mainly by the difficulty of accurately identifying their taxa and, consequently, assigning technological value to this resource. This study proposes a rapid, non-destructive strategy that authenticates&#...
O objetivo do trabalho foi avaliar a influência de diferentes doses de nitrato no meio de cultura de Murashige e Skoog-MS, visando aumentar o intervalo entre os subcultivos, através da desaceleração do crescimento, para a conservação in vitro do acesso 589 de ipecacuanha.
O objetivo neste trabalho foi estabelecer metodologias de condicionamento fisiológico (“priming”) para sementes de Brachiaria brizantha cultivar Xaraés. O experimento foi conduzido na Embrapa Gado de Corte, em Campo Grande/MS. Avaliou-se o método de imersão direta das sementes em soluções (q...
Foi investigada a eficácia de nanopartículas lipídicas sólidas (NLSs) de óleo fixo de Astrocaryum aculeatum em parasitos dactilogirídeos nas brânquias de Colossoma macropomum e seus efeitos na hematologia e histopatologia. O principal componente de ácido graxo do óleo fixo de A. aculeatum&#x...
Infectious agents shape fish populations by inducing lethal and sublethal changes that alter nutrient metabolism and metal bioaccumulation. These shifts can manifest as changes in the ionome—the specific combination of essential and non-essential chemical elements defining the whole-body composition o...
Projections of world population show that there will be a greater demand for food, fiber and energy, requiring an increase in agricultural productivity, cost reduction and sustainable use of natural resources. Thus, it is essential to consider the process of digital transformation in&#x...
In Brazil, the stingless bee species Scaptotrigona aff. depilis visits a wide range of floral resources from crops on which it is common the use of neonicotinoids. We investigated whether the survival rate of individuals of this species decreases (until the emergence) with increasi...
