The culture of black pepper ( Piper nigrum L.) is of great socio-economical importance in the northern states of Brazil, Pará especially. However, its production has been suffering the incidence of diseases such as the one caused by the Cucumber mosaic virus(CMV) and the Piper yellow mottle virs (PYMoV). Although these viruses have already been reported in many of the Brazilian states, there are too few studies that address the virus diseases which affect this culture. Hence, this project ...

The banana tree is cultivated from north to south of the country and the main cultivars used are susceptible to pests, with low productivity and some are very tall. The project aims to continue the banana breeding program underway since 1983 and aims to create and agronomically evaluate banana genotypes; assess resistance / tolerance to biotic and abiotic stresses; develop basic studies aimed at generating knowledge for pest control in support of the breeding program; use tissue culture techn

The changes in climate behavior will probably bring changes to the hydrological cycle. As a result, these variations will probably affect crop development, crop production, and water consumption.
Therefore, the project’s proposal is to determine the water requirement for irrigation in the current weather and in different future climate scenarios for the cropping of pineapple and coconut in the North, and orange, in the Northwest of the state of Rio de Janeiro, Brazil, since those are the cro ...

Historically, the agricultural activities in the northeast of Pará have been concentrated in the hands of small farmers and family-based workforce, who dedicate themselves almost exclusively to subsistence farming with focus on yuca (Manihot esculenta), corn and caupi-beans (Vigna Unguiculata) as crops with most significant socio-economic expression. This practice is done with little or no use of agricultural supplies, such as lime and fertilizers, leading the region's lands, which already have ...

This project that integrates the AgroNano Network aims to develop new materials of biological origin - Biodegradable compounds - from renewable sources, using nanotechnology and advanced characterization techniques. In other words, it aims to develop bionanocomposites containing nanoparticles out of agricultural products and by-products, adding value to different supply chains. As a result of this proposal, different products are expected to be obtained: cellulose nanostructures, nanostructured

The use of vegetable fibers as reinforcement in polymeric matrices has been an increasing demand of the industry, mainly because the whole environmental issue. The search for renewable sources, as well as the search for biodegradable products has been increasing in recent years. Pineapple fiber, more precisely from Curauá (Ananas comousus var. Erectifolius), is already being used to replace fiberglass in reinforcing polymer composites, with applications in the automotive industry. However, other ...

The recent expansion of sugarcane's culture by the mid-southern states of Brazil (Paraná, São Paulo, Mato Grosso do Sul, Minas Gerais - except the north, and Goiás), has been mostly happening on areas where degraded grasslands occur, characterized by eroded soils which are poor in nutrients, under distinct hydric regimes in regions of traditional sugarcane production. The incorporation of these flat topography areas enables mechanized harvesting and a more intensive soil use, with the eliminatio ...

Brazil has several breeds of domestic animals that have been developed from breeds brought by Portuguese colonists at the time of discovery. Over the centuries, these breeds have been subjected to natural selection in environments in which they live to the point of presenting specific characteristics to adapt to these conditions. They are known as “creole", "local" or "naturalized".


Currently, many of these breeds are endangered of extinction because over the centuries, they have

The cultures of castor oil plant, sunflower, cotton, orange, yuca and sugarcane have great importance in many regions of Brazil, and also represent a substantial part of the country's agricultural gross domestic product (GDP). They are cultures that, in most cases, occupy a considerable territorial extension with uniform surfaces, a fact which might cause them to suffer accentuated impacts of the global climate change, and subsequently cause ripple effects in food safety and other important sect

In order to achieve sustainable development from STI (Science, Technology and Innovation), Pará's Innovation System (SIPI) was created, being the state's pillar of CTI. A science and technology park (PCT) in Belém (PCT Guamá) will be set up in one of the structuring actions. This project aims to contribute to SIPI's consolidation, by setting up laboratories in the strategic areas to in order to promote the state's development, with the partnership of the state's two important research institutio ...
