| The embryo transfer technique (ET) began to be used in Brazil in the 70's, based initially on in vivo embryo production (by conventional superovulation). The potential of the technique as a tool in the multiplication of superior genotypes or in breeding programs resulted in its rapid assimilation by the productive sector, with a consequent increase of its use in the following decades. In recent years, the development of the in vitro embryo production technology has revolutionized the national ma Status: Completed Start date: Thu Jan 01 00:00:00 GMT-03:00 2009 |
| 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 ...

| Reproductive biotechnologies, particularly in vitro embryo production, can be useful to improve the milk productivity in Brazil by accelerating the genetic gain and reducing the intervals between generations. Genomic selection associated with reproductive biotechnology may be applied at the embryonic stage to promote the selection of embryos with desirable genetic traits and disposal of those with undesirable traits; consequently, maintenance costs of recipient cows would be reduced and efforts Status: Completed Start date: Sun Jun 01 00:00:00 GMT-03:00 2014 |
| 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 |

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 ...Status: Completed Start date: Fri Feb 01 00:00:00 GMT-03:00 2008 |
| This project's goal is to evaluate and quantify the impacts caused by global climate changes in Brazilian's most important economic cultures . For such a purpose, the input database of all the models of all the proposed projects will consist of projections or regional scenarios released by the Intergovernmental Panel on Climate Change (IPCC), and serve as downscalings of the global climatic scenarios. These regional scenarios will define future agricultural scenarios based in mathematical models Status: Completed Start date: Thu Jan 01 00:00:00 GMT-03:00 2009 |
