13. Growth, yield, and oil content of Brassica species under Brazilian tropical conditions
ABSTRACT Brassica oilseed species are becoming increasingly popular for industrial uses, with emphasis on biodiesel. It is of importance to evaluate the yield and oil production potential of nontraditional oilseeds for use as feedstock in Brazil. In this study, growth, yield, and oil content and their correlations were determined for eight accessions of B. j

14. Late defoliation of ‘Chardonnay’ grapevine in subtropical highland climate
ABSTRACT Chardonnay cultivar has shown great potential of planting and development in sites above 900m of Brazilian southeast for sparkling wines production. The quality of this product is related to vineyard climate and management, since both affect the vine development and grape composition. In this study, three defoliation orientations (east, west and eas

15. Amaranth in southernmost latitudes: plant density under irrigation in Patagonia, Argentina
ABSTRACT In Argentina there have been few evaluations of Andean pseudocereal plantings. This study explored the response of Amaranthus cruentus cv Mexicano to different plant densities under furrow irrigation in the lower valley of the river Negro, Patagonia, Argentina. The experimental design consisted of 3 blocks with randomized treatments (subplots), each

16. Brazil Nut Oil Extraction Using Subcritical n-Propane: Advantages and Chemical Composition
In order to provide an effective and environmentally correct alternative for oil extraction, subcritical n-propane was used under different temperature and pressure conditions to obtain Brazil nut oil. The composition of the oil was determined and compared to the oils obtained by conventional methods. The result of the extraction yield obtained using subcrit

17. Enhanced antioxidant activity of okara through solid state fermentation of GRAS Fungi
Abstract The enhancement of antioxidant activity of fermented okara was investigated using fungal solid-state fermentation. The initial fungal concentration and water activity were found to influence the enhanced antioxidant capacity of fermented okara. Extracellular enzymes, especially proteases and carbohydrases might facilitate the hydrolysis of okara pro

18. SEED METERING MECHANISMS AND TRACTOR-SEEDER FORWARD SPEED ON CORN AGRONOMIC COMPONENTS
ABSTRACT Seed metering system and tractor-seeder forward speed are factors that affect sowing. Therefore, this study aimed to evaluate sowing and agronomic components of corn as a function of seed metering mechanism and tractor-seeder forward speed, in addition to evaluating the yield data obtained from a harvester with a yield monitor. The soil of the area

19. SOYBEAN AGRONOMIC PERFORMANCE AND SOIL PHYSICAL ATTRIBUTES UNDER TRACTOR TRAFFIC INTENSITIES
ABSTRACT Machinery traffic intensification has been recurrent in intensive agriculture in annual crops, which may lead to structural soil degradation and, consequently, a reduction of its productive capacity. Therefore, this study aimed to assess the influence of tractor traffic intensification on soil physical attributes and soybean yield components. The st

21. Interference of Volunteer Corn from Different Origins and Emergence Time on Soybean Yield and Stress Metabolism
RESUMO: A ocorrência de milho voluntário em soja é favorecida pelo cultivo de milho tolerante ao glyphosate antecedendo a soja e pelo sistema de semeadura direta. A interferência de milho voluntário causa significativas perdas no rendimento de grãos de soja. Os níveis de perdas no rendimento da cultura variam com a densidade do milho voluntário, orig

23. 2,4-D Hormesis Effect on Soybean
RESUMO: Investigou-se o efeito hormético do 2,4-D, aplicado na soja em dois estádios de desenvolvimento, sobre os componentes fisiológicos de produtividade da cultura. Sementes de soja da variedade ‘AG 3680 IPRO’ foram semeadas em vasos contendo 7 L de substrato, mantidos em casas de vegetação. Foram avaliados 18 tratamentos no delineamento em bloco

24. Adubação nitrogenada e intervalos de colheita na produtividade e nutrição da erva-mate e em frações de carbono e nitrogênio do solo
Resumo Na erva-mate (Ilex paraguariensis) o principal produto colhido é composto por folhas (FO) e galhos finos (GF), resultando em elevada exportação de nutrientes, dentre eles o N. As informações técnico-científicas disponíveis para subsidiar uma recomendação da adubação nitrogenada racional são insuficientes, o que põe em risco a sustentabil
