13. Mass spore production and inoculation of Calonectria pteridis on Eucalyptus spp. under different environmental conditions
Calonectria pteridis is one of the most important causal agents of Calonectria leaf blight (CLB) of Eucalyptus spp. in Brazil, which is a limiting factor for growth of Eucalyptus plantations. In this study we developed standard procedures for in vitro mass spore production and inoculation of C. pteridis for screening plant species and clones for resistance t

14. Adubação nitrogenada e inoculação com azospirillum brasilense em híbridos de milho / Nitrogen application and Azospirillum brasilense inoculation on maize hybrids
Maize is one of the worlds most important cultivated cereals; however, it presents great challenges for correct fertilization management. Its high nitrogen demand has been the major cause of excessive applications of synthetic nitrogen fertilizers in the crop. As a result, both environmental and economical problems have increased. Therefore, alternative meth

15. Isolamento e caracterização de bactérias promotoras de crescimento vegetal de lavouras experimentais de arroz sob diferentes níveis de fertilização
Chemical fertilization is widely used for increased crop productivity, but its production and use lead to serious environmental damage. To reduce the use of fertilizers, one can make use of plant growth promoting rhizobacteria (PGPR), which are plant-associated bacteria that increase plant health, size and yield through various mechanisms. PGPR effectiveness

17. Fotossíntese, crescimento e composição química em plantas de Theobroma cacao L. submetidas a diferentes concentrações de silicato de potássio e sua interação com insetos-praga / Photosynthesis, growth and chemical composition in plants of Theobroma cacao L. subjected to different concentrations of potassium silicate and its interaction with insect-pests
The control of insect pests through the use of pesticides, is still the most method used in the cultivation of cocoa. However, due to environmental issues, there need to seek new alternatives of control less harmful the environment and to humans. In this context, silicon is a nutrient that is being used in various cultures, due to its beneficial effects on p

18. Rhizosphere bacterial communities of potato cultivars evaluated through PCR-DGGE profiles.
The objective of this work was to determine the shifts on the PCR-DGGE profiles of bacterial communities associated to the rhizosphere of potato cultivars, in order to generate baseline information for further studies of environmental risk assessment of genetically modified potato plants. A greenhouse experiment was carried out with five potato cultivars (Ac

24. THE USE OF BIO-DIGESTERS IN SMALL AND MEDIUM RURAL PROPERTIES WITH EMPHASIS ON VALUE ADDING: A CASE STUDY FROM NORTHWESTERN REGION OF RIO GRANDE DO SUL STATE / O USO DE BIODIGESTORES EM PEQUENAS E MÉDIAS PROPRIEDADES RURAIS COM ÊNFASE NA AGREGAÇÃO DE VALOR: UM ESTUDO DE CASO DA REGIÃO NOROESTE DO RIO GRANDE DO SUL
From the duration of the Kyoto Protocol, there has been a renewed interest in technology of bio-digesters. As they allow a reduction in the emission of greenhouse gases compared to other waste treatment methods, their deployment can permit the marketing of carbon credits, resulting in money. The present study aims to analyze the process of dissemination of t
