1. Watercress crop to salinity using a NFT hidroponic system / Resposta da Cultura do Agrião à Salinidade Utilizando um Sistema Hidropônico do Tipo NTF
After the Brazilian agriculture started to be outstanding in the scenery of the scientific researches, the great challenge started to be the productivity standardization in whole national territory. One of the main focus is being the semi-arid area for its water scarcity, so much quantitative as qualitative, for being an area with low annual precipitation an

2. Disponibilidade de água e desenvolvimento de plantas de sorgo (Sorghum bicolor (L.) Moench.) e braquiária (Brachiaria brizantha (A. Rich) Stapf cv. Marandu) consorciadas / Water availabity and development of sorghum plants (Sorghum bicolor (L.) Moench.) and Brachiaria (Brachiaria brizantha (A. Rich) Stapf cv. Marandu) associated.
The acknowledgement of the pluviometric offer and the variation of water in the soil are preponderant factors for the efficient handling and the success of the croplivestock integration system Therefore, the present work has evaluated the productivity and development of sorghum plants AG-1018 and Brachiaria brizantha cv. Marandu associated, under periods of

3. Forage based animal production systems and sustainability, an invited keynote
Forages are essential for the successful operation of animal production systems. This is more relevant to ruminants which are heavily dependant upon forages for their health and production in a cost-effective and sustainable manner. While forages are an economical source of nutrients for animal production, they also help conserve the soil integrity, water su

4. Sustentabilidade e qualidade do solo em propriedades de cana-de-açúcar orgânica e convencional / Sustentability and soil quality in organic and conventional sugarcane establishments
Soil quality evaluation is an important strategy, as it allows producers to focus agriculture techniques to constantly develop and maintain adequate, selfsustainable productions equilibrium. This study evaluated rural activities environmental impact by the system APOIA-NovoRural, as well as the influence of different sugarcane production systems on soil qual

5. Validation of the NUTMON model for the diagnosis of agricultural management: study on two family farms in Rio de Janeiro State. / Validação do modelo NUTMON para o diagnóstico do manejo agrícola: Estudo em duas propriedades familiares do Rio de Janeiro.
This study had the following hypothesis: the agricultural production systems adopted by small farmers brings about nutrient negative balances to soil, which causes the loss of soil fertility and crop yield decline in the time span. The general objective of this study was to validate the NUTMON model of the Food and Agriculture Organization of the United Nati

6. Typology of the system of handling of native açai crop practiced by the riverine ones in Belém, State of Pará / Tipologia do sistema de manejo de açaizais nativos praticado pelos ribeirinhos em Belém, Estado do Pará
O açaizeiro (Euterpe oleracea Mart.) é um dos principais componentes da renda e do consumo de ribeirinhos do Município de Belém, Estado do Pará, que manejam o açaizal para a produção de frutos, tendo o palmito como subproduto. O objetivo deste trabalho foi o de identificar e caracterizar os diferentes tipos de manejo de açaizais nativos, praticados

7. ANÁLISE ECONÔMICA E EXPERIÊNCIA COMPARATIVA ENTRE AGRICULTURA DE PRECISÃO E TRADICIONAL / ECONOMICAL ANALYSIS AND COMPARATIVE EXPERIENCE BETWEEN PRECISION AND TRADITIONAL AGRICULTURE
The study was developed in the farm Anna, located in the municipal district of Não-me-Toque RS, in the period included among the crops of 2002/03 and 2005/06. In the precision farming worked areas were generated yield maps of the culture, with information collected through sensors that equip the harvester, maps of soil fertility, with are based in geo-refer

8. Contribuição da fixação biológica de nitrogênio na produção sustentável da cultura de cana-de-açúcar. / Biologicals nitrogen fixation contribution in sugarcanes crop sustainable production.
Despite sugarcanes Biological Nitrogen Fixation (BNF) research efforts which have been carrying on in Brazil, most of its varieties still need nitrogen fertilizer complement, and the cost of this supply trends to raise following the petroleum price. Thus, the scientific research has worked on finding alternatives to nitrogen fertilizer through varieties with

9. Influence of systems of handling in the production and in the reservations of precocious peach tree (Prunus pérsica (L.) Batsch.) cultivated in tropical climate. / Influência de sistemas de manejo na produção e nas reservas de pessegueiro precoce (Prunus pérsica (L.) Batsch.) cultivado em clima tropical.
The precocity maturation is the main factor of economical success of the producing of peach from São Paulo, in view of that fact the very big demand exists goes new techniques that make possible the improvement of the quality of the fruits and the larger precocity in the crop. This work seeks to verify the influence of the systems of prunings and maintenanc

10. Diagnose of water use on irrigation of crops in hydrological basin of Jundiai-Mirim river / SP / Diagnostico do uso da agua na irrigação de culturas na bacia do Rio Jundiai-Mirim / SP
Recent researches demonstrate that the use of water for agriculture represents 60% of total consumption of freshwater in Brazil and that many irrigation systems do not have any control of the use of water for this activity. Also, it is estimated that 40% of the water applied in irrigation is misused by percolation and superficial drainage, what generates a g
