Abstract:
... ‘BRS Vitória’ is a seedless table grape released by the grape breeding program of EMBRAPA in 2012. It has attracted great interest from grape growers because of the high fertility of its buds, its exotic and pleasant taste and its tolerance to downy mildew (Plasmopara viticola). The aim of this study was to characterize the agronomic and productive behavior of the grape ‘BRS Vitória’ under the tro ...

Abstract:
... This work aimed to evaluate the capture success of early life stage fish using three sampling methods (hand net, plankton net, and quatrefoil light trap). The hand net presented better sampling efficiency in the studied lagoons, with the capture of 13 exclusive taxa. Young migratory species, such as Prochilodus argenteus, P. costatus and Salminus hilarii, were only collected in the hand net, sugge ...

Abstract:
... Boron is one of the micronutrients that mostly limits crop yield in Brazil, especially for tomato. When boron is deficient, there is initially growth reduction in meristematic tissues (root ends and branches), although for tomato, this behavior has not yet been characterized. The aim of this work was to characterize the effects of boron deficiency on biometric characteristics, anatomical changes a ...

Abstract:
... There is a growing interest by the Brazilian sugarcane (Saccharum sp.) industry in removing sugarcane straw from the field to use as raw material for increasing bioenergy production (e.g., second generation and co-generation). In contrast, straw has an essential role in sustaining critical soil functions, so indiscriminate straw removal can jeopardize soil quality and consequently reduce crop yiel ...
