Interhabitat variation in diplochory: Seed dispersal effectiveness by birds and ants differs between tropical forest and savanna
(Elsevier B.V., 2019-06-01)
Diversified assemblages of frugivores interact with fruits/seeds in tropical environments. Species within assemblages vary largely in body size, abundance, seed treatment and places of seed deposition, with possible delayed ...
Potential of methane and carbon dioxide in vitro production by urochloa hybrid subjected to periods of coexistence with weedsPotencial de produção in vitro de metano e dióxido de carbono pela urochloa híbrida submetida a períodos de convivência com plantas daninhas
(2020-05-01)
The increased world population has raised the demand for animal proteins, forcing livestock to become productive, efficient, and environmentally sustainable. This study aimed to assess the effect of weed coexistence on ...
The presence of invasive grasses affects the soil seed bank composition and dynamics of both invaded and non-invaded areas of open savannas
(2020-12-15)
One of the major threats to tropical savannas globally is the invasion by alien grasses. In systems frequently disturbed, individuals can be recruited from the seed bank, and areas under natural regeneration can be more ...
Tractor performance and corn crop development as a function of furrow opener and working depth in a Red Latosol
(2015-01-01)
To use a no-tillage system, the producer must know the ideal tool for each condition encountered in the soil. In seeding, the function of the furrow opener is loosening and disturbing the soil, but if the opener lacks the ...

(2010)
The objective of this work was to evaluate the growth of yellow passion fruit seedlings in response to increasing simple superphosphate levels. The experiment was carried out under greenhouse conditions in the campus of ...
Comprimento radicular e nutrição de cultivares de painço em resposta à calagem
(2013)
Information on improved cultivars of fall panicum and cultural practices concerning its cultivation is scarce in Brazil. So, the objectives of this research work were to evaluate root length and the mineral nutrition of ...
Appropriate hydration period and chemical agent improve priming in brachiaria seeds
(Escola de Agronomia e Engenharia de Alimentos/UFG, 2016)
Priming is an alternative to improve the performance of seeds that have germination problems, such as Urochloa brizantha seeds. This study aimed at evaluating the appropriate hydration period and chemical agents used for ...
Electrical conductivity of different common bean seeds genotypes
(ABRATES - Associação Brasileira de Tecnologia de Sementes, 2013)
The electrical conductivity test is a fast and non-subjective method used to assess seed physiological potential. Thus, the objective of this study was adapting the methodology for conducting the electrical conductivity ...
RESISTÊNCIA DE VARIEDADES DE SOJA À MORTE DE PLÂNTULAS CAUSADA POR COLLETOTRICHUM TRUNCATUM
(Instituto Biológico, 2022-01-10)
Anthracnose causes high damages in soybean yield, mainly in warm and wet regions. This study was aimed to evaluate the resistance of various soybean varieties to Colletotrichum truncatum. To obtain the inoculum, the isolate ...
Physiological and biometric indices in bean under different doses of phosphorusÍndices biométricos e fisiológicos em feijoeiro sob diferentes doses de aduba̧ão fosfatada
(2010-01-01)
The study had the objective of evaluate the growth of bean cultivar Carioca early cultivated during the rainy season under different doses of phosphorus applied to soil. We adopted the experimental design at random blocks, ...
