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. Pyrolysis of the Caupi Bean Pod (Vigna unguiculata): Characterization of Biomass and Bio-Oil
The use of agricultural residues for the production of bio-oil is an important alternative to the use of fossil fuels. In this study, the Caupi bean pod (Vigna unguiculata) was characterized and used as biomass in the production of bio-oil. This biomass was evaluated in terms of physicochemical, morphological (scanning electron microscopy (SEM)), and thermal

15. 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

16. Update on new GH-IGF axis genetic defects
ABSTRACT The somatotropic axis is the main hormonal regulator of growth. Growth hormone (GH), also known as somatotropin, and insulin-like growth factor 1 (IGF-1) are the key components of the somatotropic axis. This axis has been studied for a long time and the knowledge of how some molecules could promote or impair hormones production and action has been g

19. 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

21. Soybean in succession to the residue of the sorghum/Paiaguás grass straw with Azospirillum brasilense
ABSTRACT One of the alternatives to achieve agriculture with sustainability and reduction in production costs, mainly with fertilizers, is the formation of straw from the previous crop and the use of genus Azospirillum bacteria. The objective of this study was to evaluate the agronomic characteristics and yield of soybean, cultivated in areas under straw of

24. Relationship between milk production system and milk traits and somatic cell counts in Brazilian Murrah buffaloes: a multivariate analysis
ABSTRACT. The purpose of this study was to evaluate the monthly milk production and quality of buffaloes from two milk production systems in the Brazilian northeast using the multivariate analysis: principal component analysis (PCA). A total of 2,506 individual milk recordings were performed in two production systems, containing information on milk productio
