Productivity and forage quality of elephantgrass (Pennisetum purpureum) are directly affected by weed interference. The difficulty of control of these species is one of the main barriers to production and use of the forage as feedstock, as well as to the production of biomass for energy use. Despite the great progress in agro-ecological weed control techniques, herbicides are still indispensable. Thus, the rational use practices of these products should be improved in order to produce quality fo

Spittlebug, Mahanarva spectabilis (Hemiptera: Cercopidae) is capable to cause drastic losses in production and quality of pastures established with grasses. Currently, the use a grass resistant cultivar, to be obtained by means of constitutive antibiosis, is the best spittlebug controlling method. However, the time required for releasing a cultivar after detecting a spittlebug-resistant strain is relatively long. Allied to this, one should take into consideration that the adaptations of

Brazil leads the research on reproduction of forage plants, but faces as a challenge the low diversity of pastures, mainly formed by apomictic plants. Apomixia - asexual reproduction by seeds - is an area of biotechnology with great potential to optimize the genetic improvement of these species, as it develops genetic materials and procedures for plant cloning by the direct use of seeds. This project proposes the determination of strategies to regulate the genes associated with the mode of repro

Pastures of Cynodon spp. and elephantgrass ( Pennisetum purpureum Schum.) have their productivity and forage quality directly affected by weed interference. The difficulty of controlling weeds is one of the main obstacles to growing and using these forage crops as an input in animal feeding, as well as in the production of elephantgrass biomass for energy use. Despite the progress in agroecological weed control techniques, herbicides are still indispensable, especially in crops on ...

The growing biofuel industry generates by-products that have shown promise as energy and protein feeds in ruminant diets. The objective of this project was to determine the effects of by-products of biodiesel production, obtained from different sources of oilseeds, on the in vitro degradability of nutrients, in vitro ruminal fermentation and methane gas production. Palisadegrass ( Brachiaria brizantha) was used as a model. Its isolated incubation was considered as a contro ...

Alzheimer's disease (AD) is a progressive degenerative disease of the central nervous system (CNS) that mainly affects people over 65 years of age, resulting in loss of memory and cognitive functions such as language, attention, orientation and reasoning. According to the World Health Organization (WHO), 24.3 million people worldwide suffered from AD and other types of dementia in 2007, with a doubling of this number every 20 years. That Organization also stresses that the impact of AD in develo

This project aimed to present reuse alternates for the waste produced in the industrial processing of açaí, and thus obtain processing plants that minimize the release of waste products. A previous evaluation of this matter pointed out technological alternatives through which would be possible to: I) reuse the residue inside or outside the processing plant, or, II) produce byproducts with aggregated value. The project proposed to develop support technologies to the açaí agroindustrial complex, w ...

GM crops that are resistant to glyphosate have created a new scenario in Brazilian agriculture. Glyphosate has been generally used mainly in soybean farms in the Brazilian states of Rio Grande do Sul, Santa Catarina and Paraná. In the state of São Paulo, glyphosate is widely used in orchards, especially citrus ones. The repeated use of glyphosate has given rise to cases of weed resistance to this herbicide in different places of the country. The trend is that new glyphosate resistant crops such ...

Embrapa Gado de Leite has the main Elephant Grass Germplasm Active Bank (BAGCE) in the country. However, the main species of grasshopper (Hemiptera: Cercopidae) and the genetic variability for resistance to these pest insects were not known. Therefore, the objective of this work was to study the population dynamics of spittlebugs and to evaluate the accessions of the elephant grass germplasm bank, regarding resistance to Mahanarva liturata. The population dynamics of cercopids in Coronel Pacheco

This research project aims to obtain information about wood harvesting, energy supply and carbon credit market using five both native and exotic forest species in experimental homogeneous and mixed plantation systems in the counties in Pará. Furthermore, as additional information, activities that open up new guidelines regarding fertilization, dissemination and phytosanitary aspects of the species in question will be carried out throughout eight actions plans. The species of interest are: paricá ...
