1. Crescimento vegetativo, produÃÃo e composiÃÃo quÃmico-bromatolÃgica da palma forrageira consorciada com cajà (Spondias spp) / Vegetative growth, production and chemical composition of cactus pear intercroppedwith caja (Spondias spp)
In the Brazilian Northeast the efficiency of the animal production was increased when combining native pastures and grass adapted in consequence of the low productivity of the native grass, mainly at that time of drought. The importance of the forager palm as one of the most important grass, for your high productivity and quality for the ruminant. However, t

2. Adubação fosfatada no plantio da cana-de-açúcar a partir de torta de filtro enriquecida com fosfato solúvel / Fertilization in the planting of sugarcane from the filter cake enriched with soluble phosphate
The phosphorus is considered an essential element for the plants and is in low amount in the Brazilian soils. The filter cake, mixture of sugarcane bagasse and sludge of decanter tanks, presents high organic matter, phosphorus and calcium content. The phosphorus existent in the filter cake is organic. The liberation of phosphorus and nitrogen happen gradual,

3. EMISSION OF NITROUS OXIDE AND CARBON DIOXIDE AFTER APPLICATION OF PIG SLURRY AND CATTLE DEJECTIONS IN AN HAPLUDALF / EMISSÃO DE ÓXIDO NITROSO E DIÓXIDO DE CARBONO APÓS APLICAÇÃO DE DEJETOS DE SUÍNOS E BOVINOS EM UM ARGISSOLO
Emission of greenhouse effect gases due to the agricultural use of the dejections of animals as fertilizers, as well as the mineralization of the carbon of those materials in the soil healthy aspects are still relatively a little studied in Brazil. This work was accomplished to evaluate: 1) the annual emission of nitrous oxide with the use, in the corn, of m

4. Nitrogênio (15 N) e atividade das enzimas redutase do nitrato e glutamina sintetase na cultura do milho em plantio direto / Evaluation of you cultivate of corn the application of Nitrogen and molibdênio and effect on the activity of the enzymes nitrate redutase and glutamina sintetase
This work was developed using data of the rehearsal conducted in the experimental station of CoimbraMG, area belonging to Federal University of Viçosa. It was aimed at through this theory: 1 - to evaluate the effect of the Nitrogen manuring on the activity of the enzymes nitrate redutase (NR) and Glutamina sintetase (GS) in corn cultivars in reduced spacing

8. Fertilizantes de leguminosas: tecnologia inovadora de adubação verde para provisão de nitrogênio em sistemas orgânicos de produção. / Legume fertilizers: innovative technology of green manuring for nitrogen supply in organic farming systems.
One of the main limitations to the organic food production is the reduced availability of low cost and efficient nitrogen (N) sources. Green manuring practices, in rotation or intercropped, have been used, but hardly are they able to supply crop needs. This dissertation presents an innovative technology of green manuring, derived of the cutting, dehydration

9. Caracterização agronômica de espécies de Crotalaria L. em diferentes condições edafoclimáticas e contribuição da adubação verde com C. juncea no cultivo orgânico de brássicas em sistema plantio direto. / Agronomic evaluation of Crotalaria species in different environmental conditions and the contribution of green manuring with C. juncea on organic production of cabbage and cauliflower under no-tillage system.
The objective of this work was to evaluate growth of Crotalaria species in different soil and climate conditions and to investigate the contribution of Crotalaria juncea, as a cover crop, on organic cultivation of cabbage and cauliflower, under no-tillage system. Five experiments were conducted. Three of them referred to the performance of Crotalaria species

10. Treatment of the chromium-containing solid wastes from leather industry: use in adsorption process and as nitrogen source in agriculture. / Tratamento de rejeitos sÃlidos contendo cromo da indÃstria de couro: uso em processos de adsorÃÃo e como fonte de nitrogÃnio na agricultura.
The leather industry has a great economic importance for Brazil, however it is responsible for the generation of solid wastes containing chromium (sawdust and stripes of wet blue leather), which need suitable disposal for being classified as class 1 waste. The objectives of this work were to treat this waste for chromium removal and to use the resultant mate
