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

This project aims to recover legal reserve areas (ARL) or areas of permanent preservation (APP), in regions of family agriculture at the Brazilian Oriental Amazon, in the hopes of reducing impacts resulted from agricultural and forest practices. The project aims to train at least 150 family farmers in management of natural resources in areas which are close to bodies of water, and also to recover and monitor these areas' environment. The project will be developed in micro-basins of the Bragança, ...

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

Currently, Brazil is the fourth largest consumer of fertilizers in the entire world; on average, the fertilizers may represent from 25 to 40% of the variable cost of the most important agricultural production systems in the country. One of the main cost variables is the fact that great quantities of applied nutrients via fertilizers are lost through volatilization and leaching. Thusly, methods of nutrient fixation which allow their extended-release in the soil might contribute to a more rational

The goal of this project is to develop an integrated database system for the Department of Vegetal Sanity (DSV), the Secretary of Agriculture and Stockbreeding Defense of the Agriculture, Stockbreeding and Provision (Mapa), hoping to facilitate processes of risk analysis of plagues that attack vegetable products. The vegetable product imports which can be potential spreaders of plagues is normatized by the International Plant Protection Convention (IPPC), which is linked to the Committee of Sani

Cattle farming is one of the most important activities of Brazilian agribusiness. Brazil is the world's largest beef exporter, holds the world's largest commercial herd, and is the world's third largest producer and consumer of beef and the world's seventh largest milk producer, with about 4% of the world's total. In spite of its large overall production, Brazilian cattle farming remains low in productivity, indicating a great potential for improvement and expansion of this sector of the economy

Silvopastoral systems may be an option to prevent grassland degradation because of the potential to control erosion and the ability of some tree species to add nitrogen and other nutrients to pasture, improving soil fertility. In view of this potential, in-depth evaluations of the soil and plant components of these systems are critical. The objective of this project was to verify the effect of trees on soil quality (fertility, biomass and microbial activity) and to evaluate the dry matter produc

The Extractive Reserve (Resex) "Forever Green" was created in 2004, in an area of 1,288,717 hectares in Porto de Moz- PA. The families that live in this reserve survive especially of artisan fishing, of subsistence agriculture and of raising domesticated buffalos. The region's income increase face the lack of technical knowledge and difficulty of direct access to the consumer market as main obstacles, point out locals. This project aims to organize and develop practices inside Resex with the int ...

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 state of Pará is the largest northern producer of rice, corn and caupi beans, and the second largest soy producer. These species are cultivated in all the macro-regions of the state, where the Research and Technology Transfer Support Centers (NAPTs) of the Oriental Amazon are located. Based on this structure, this project aims to propose a strategy for the disclosure and transference of cultivars that are adequate to the region's producers' socio-economic and environmental conditions, throug ...
