1. Fruit quality and occurrence of mildew in Niagara Rosada grown under plastic cover and defoliation rates
ABSTRACT The purpose of this study was to evaluate the agronomic behavior of the Niagara Rosada variety cultivated under plastic cover, using defoliation intensities, and its influence on the Plasmopara viticola. The experiment was conducted in Francisco Beltrão, PR, Brazil, in a vineyard of Niagara Rosada variety in a trellised system during the 2016/2017

2. Trellis systems, rootstocks and season influence on the phenolic composition of ‘Chenin Blanc’ grape
ABSTRACT: The biosynthesis of phenolic compounds might be influenced by environmental factors, such as solar radiation, temperature and relative air humidity, and production system. Some components of the production system, particularly the trellis system and rootstock, might change the phenolic composition of grapes due to microclimate of the cultivation re

3. BIOPHOTONICS: ACCLIMATION OF PRE-SPROUTED SUGARCANE SEEDLINGS IN PROTECTED ENVIRONMENT
ABSTRACT Sugarcane is considered one of the main alternatives for biofuel production and an important product of Brazilian agriculture, so it is indispensable to adopt new techniques for its cultivation and management. Thus, the present study aimed to evaluate the effect of the quality of supplemental lighting, based on light-emitting diode (LED), on the acc

4. Performance and selection of tomato cultivars for organic cultivation in greenhouse
ABSTRACT Production of tomato fruits in organic systems has difficulties such as the use of adequate cultivars. The hypothesis is that organic cultivation has strength dependency of the selection of appropriate genotypes to increase the economic viability of fruit production. The present work aimed to test and obtain, under organic greenhouse system, cultiva

5. Production of docosahexaenoic acid by Aurantiochytrium sp. ATCC PRA-276
Abstract The high costs and environmental concerns associated with using marine resources as sources of oils rich in polyunsaturated fatty acids have prompted searches for alternative sources of such oils. Some microorganisms, among them members of the genus Aurantiochytrium, can synthesize large amounts of these biocompounds. However, various parameters tha

6. Microbial Communities in Soil Cultivated with Muskmelon under Different Management Systems
ABSTRACT Microorganisms have a fundamental importance in agricultural ecosystems and may be influenced by several factors, including soil management. The aim of this study was to evaluate the effects of cropping systems and soil covers on the microbial community in soil cultivated with muskmelon (Cucumis melo L.). The experiment was conducted in a randomized

7. Sorghum silage production system in Cariri, Paraíba
The objective of this study was to characterize the sorghum farming and ensiling systems in the Cariri region of Paraíba State (Brazil), and to identify different groups of producers based on productive characteristics using frequency distributions, and principal component and cluster analyses. A total of 100 milk producers in the Caturité and Boqueirão m

8. Tensile strength and friability of an Alfisol under agricultural management systems
Management systems may influence the structural quality of soils. Tensile strength (TS) and friability (F) are indicators of soil structural quality. The aim of this study was to evaluate the TS and F of an Alfisol under different management systems. The treatments were as follows: (i) soil under conventional system with growing maize after tobacco cultivati

9. Ochratoxigenic fungi associated with green coffee beans (Coffea arabica L.) in conventional and organic cultivation in Brazil
The genera Aspergillus comprises species that produce mycotoxins such as aflatoxins, ochratoxins and patulin. These are cosmopolitan species, natural contaminants of agricultural products. In coffee grains, the most important Aspergillus species in terms of the risk of presenting mycotoxins belong to the genera Aspergillus Section Circumdati and Section Nigr

11. Pruning cycles and nitrogen fertilization of coffee feilds conducted in the "safra zero" system.
Modern, competitive and cost effective coffee production requires plants with high productivity that are more adapted to mechanical and manual harvesting. ?Safra Zero? is a cultivation system designed to limit plant height and eliminate the need for expensive harvesting during years of low productivity, which usually follow years of high productivity. This s
