14. MORPHOLOGICAL AND GENETIC BEHAVIOR OF CASTOR BEAN CULTIVARS IN LOW ALTITUDES IN THE COASTAL TABLELAND OF SERGIPE. / COMPORTAMENTO MORFOLÓGICO E GENÉTICO DE CULTIVARES DE MAMONEIRA EM CONDIÇÕES DE BAIXAS ALTITUDES NOS TABULEIROS COSTEIROS DE SERGIPE.
The planted area of castor oil in exploration occurs in a sustainable manner, its necessary the use of plants improved and adapted to the region of cultivation, reducing costly and degrading agricultural practices, providing the identification and acquisition of genetically superior material. This study aimed to evaluate the behavior and genetic parameters b

15. Desempenho competitivo do estado de São Paulo e da região sul do estado de Goiás na produção de cana-de-açucar
The sugar cane is an important activity which generates energy and with high capacity to link many sectors of its economy. After a plenty of prohibitions and challenges faced by the sector in the two last decades, such as the Pro-alcohol project, the success of the car with alcohol engine, the beginning of the exportation of sugar for the private sector, the

16. Estrutura do solo e aporte de matéria seca, carbono e nitrogênio em sistemas de manejo do solo
A utilização de sistemas conservacionistas como o plantio direto e a rotação de culturas, incluindo plantas de cobertura do solo, podem contribuir na melhoria da estrutura do solo, distribuição das raízes e manutenção de carbono e nitrogênio do solo. Os objetivos do trabalho foram: 1) avaliar a estrutura do Latossolo Vermelho e associá-la à distr

17. CONTROL OF GROWTH AND DEVELOPMENT OF POTATO TUBER SEED THROUGH THE ELECTRICAL CONDUCTIVITY OF THE NUTRIENT SOLUTION / CONTROLE DO CRESCIMENTO E DESENVOLVIMENTO DA BATATA SEMENTE ATRAVÉS DA CONDUTIVIDADE ELÉTRICA DA SOLUÇÃO NUTRITIVA
Potato average production in Brazil is well above the worlds one, but in Rio Grande do Sul the opposite is true, as this state holds one of the countrys smallest mean production. This fact is mainly due to the use of low quality tuber seed. The multiplication of virus-free propagation material, obtained by meristem culture, requires more efficient and econom

18. Coeficientes de cultura (Kc) e crescimento vegetativo de âAcaià Cerradoâ (Cofeea arabica L.) associados a graus-dia (2 ano). / Crop coefficients (Kc) and vegetative growth of âAcaià Cerradoâ (Coffea arabica L.) associated to degree days (2nd year)
Crop coefficients (Kc) for arabic coffee plants are usually related to days after planting or Julian calendar, not considering the variation in the developing rates of the crop for places and years. There is a tendency for using meteorological variables, that consider the climatic effect on the lasting of the developing phases of crop. This study had the obj

19. Atributos químicos e microbiológicos do solo após aplicações de resíduos de suínos em sistema de plantio direto
Intensive rearing of swine livestock results in a huge amount of liquid residues (pig slurry), which can be a source of contamination to the environment. This residue contains phosphorus nitrogen and other nutrients; therefore it seems appropriate to use it on cropped soils as fertilizer. This work aimed to evaluate chemical and microbiological changes in th

20. Caracterização química de resíduos da produção de biodiesel compostados com adição mineral / Chemical characterization of residues from biodiesel production composted with mineral addiction
The production of biodiesel has in agriculture its base of sustentation. The culture of sugar cane and oleaginous species as castor oil plant after processing to obtain alcohol and vegetal oil, respectively, generates organic residues. These residues when used in agriculture in the compost form make possible the reduction of production costs and increase of

21. Potencial do lodo de esgoto calado como insumo agrÃcola para a cultura do milho em latossolo vermelho
The sewage sludge is a by-product resulting of the sewage treatment that contains high organic matter concentration and that, properly applied, it can to supply improvements in the soil fertility. The objective of this study was to evaluate the sewage sludge agricultural potential. The experiment was accomplished in field, in the year of 2004, with randomize

22. Pathogenicity of Fusarium oxysporum f. sp. phaseoli, nitrogen fertilization and common bean yield. / Patogenicidade de Fusarium oxysporum f.sp. phaseoli, adubação nitrogenada e produtividade de feijão.
Brazil is one of the biggest world growers and consumers of common bean, that is one of the main protein sources in the feeding habits of the significantly population plot. Even if present prominence in the world common bean production, the Brazilian yield is very low. In the spring-summer 2002 the yield was about 926 kg.ha-1, a value much lower than the cro

23. Synthesis and Accumulation of Nitrite in Soybean Nodules Supplied with Nitrate 1
Nodulated soybean plants (Glycine max [L.] Merr) were grown in sand culture without combined N or with a continuous supply of nitrate in nutrient solution. Moderate nitrate concentration (30 milligrams N per liter) had little effect on nodule weight/plant while high nitrate concentration (100 milligrams N per liter) depressed nodule weight/plant by 70 to 80%

24. Use of a Promoter Trap To Identify Bacillus cereus Genes Regulated by Tomato Seed Exudate and a Rhizosphere Resident, Pseudomonas aureofaciens
The goal of this study was to identify genes in Bacillus cereus, a bacterium commonly associated with plant seeds and roots, that are affected by compounds originating from a host plant, tomato, or another rhizosphere resident, Pseudomonas aureofaciens. We constructed a B. cereus chromosomal DNA library in a promoter-trap plasmid, pAD123, which contains a pr
