The use of nanotechnology has been putting nanoparticles and nanostructures in contact with live organisms in ways not yet fully understood. In agriculture, this interaction can occur on a large scale, such as in the applications of controlled release nanostructure-encapsulated pesticides whose toxicity inherent to the drug release system still requires continual verification. Cases like this have motivated the proposal of this project, whose objective was to evaluate the potential impact on liv

Sustainability of traditional cultivation systems (slash-and-burn) depends especially on long periods of set-aside in order to reestablish the stock of the soil's nutrients and raw organic material used and/or lost during the agricultural period. Population growth and decrease in the region's secondary vegetation availability has progressively reduced the set-aside period, subsequently increasing the pressure on riparian areas and cultivated ones. The result if degradation of natural resources a

Molecular genetics is an additional tool which provides information for the detection and exploitation of genes or chromosomal regions with large influence on economic traits. This comes from the development of dense maps of linkage disequilibrium among genetic markers for many livestock species. Although each type of genetic marker has advantages and disadvantages, the only polymorphisms with enough density to meet important requirements for gene mapping are the Single Nucleotide Polymorphisms

Brazilian native fruit species are excellent generators of income and job opportunities to family farmers and micro-entrepreneurs especially from the Northern and Northeastern regions of Brazil. Species such as the Platonia insignis, Myrciaria dubia, Byrsonima crassifolia and the Spondia mombin L. have been frequently cited as economically promising in the field of family farming, due to the myriad of business possibilities linked to the ever increasing demand of

The development of new technologies for the agricultural sector from cutting-edge areas such as nanotechnology is a demand Embrapa has recognized. The crosscutting and pervasive nature of developments in this area also makes it difficult to understand models that allow these new technologies to actually reach the production sector. It is evident that when a company in the food sector assimilates new technology, its behavior is structurally different from that of a company in the plastics industr

This project aims to develop, evaluate and validate the environmental and social sustainability of technical-economic milk production systems based on Integrated Crop-Livestock-Forest Systems (ICLFS), with the use of the main plant species silage corn, cowpea, Piata grass, eucalyptus, chestnut; and Dutch x Gir crossbreeds.

Genetic Vegetable resources, globally, involve a number of around 300,000 identified species, of which 30,000 are edible and only 30 consist of foods that feed the world's population. However, from this total, only three species provide 50% of proteins necessary in a regular diet (rice, wheat and corn). This situation has been stimulating a great number of researchers in the quest to increase the number of species dedicated to feed the population. Brazil is considered the world's greatest source

Germplasm banks have as their main purpose to get together in one place part of the genetic variability (germplasm), in order to prevent the loss of genes or gene combinations (genetic erosion), thus ensuring a broad genetic basis for research programs. Germplasm banks are usually made up of local races (ethnovarieties), improved varieties and wild species of the same genus. And because they bring together genetic constitutions of different origins and different breeding levels, they can be grea

In order to have the country keep growing and to open new markets, some sectors still require value aggregation to their products, which can only be achieved through the continuous incorporation of new technologies. In special, the quality and certification of agricultural products, biotechnology, agroenergy, environmental monitoring, new uses of agricultural products, precision agriculture and traceability, the inputs (fertilizers, pesticides) industry, innovation in medicine for veterinary use
