| The program of genetic improvement of the cupuaçu tree ( Theobroma grandiflorum) needs to tend to the demand of new cultivares, especially of those resistant to the Monilophthora perniciosa fungus, the agent responsible for causing the deformity known as witch's broom disease, and also to increase as much as possible the genetic base of planting material. This project aims to develop new technologies which promote the quick multiplication of selected cultivares, as well as to early select ...

| The total extension of the grasslands in Brazil still isn't quantified with precision, and even less are the degraded pastures. The demand for technologies that are able to quickly map and monitor the areas which are occupied with grasslands and their level of degradation, with precision and low costs, are ever growing. This research investigates the potential of the correlation between the data extracted from satellite images and data regarding grassland degradation obtained in field s ...Status: Completed Start date: Sat Aug 01 00:00:00 GMT-03:00 2009 |
| The soil is of vital importance for the planet. The soil is the main support of agriculture; for climate change, it is one of the regulating elements of the water cycle. Status: Completed Start date: Thu Dec 01 00:00:00 GMT-03:00 2011 |
| 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. Status: Completed Start date: Tue Jan 01 00:00:00 GMT-03:00 2013 |
| 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 ...

| 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 ...

| 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 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 Status: Completed Start date: Thu Jan 01 00:00:00 GMT-03:00 2009 |
| Soil quality may be measured through the use of indicators, which are attributes that measure or reflect the environmental state or condition of sustainability of the referred ecosystem. The knowledge regarding the spatial distribution of soil quality and its levels becomes essential in this case, once it favors the study of their relation with the type of soil management, with the environmental impact and the productive capability of agricultural systems. For such, it is important to have a met Status: Completed Start date: Tue Sep 01 00:00:00 GMT-03:00 2009 |
