Abstract: in alentejo region low temperatures and soil waterlogging during autumn- winter season are limiting factors for vegetable production under field conditions. short -day onions can be an option to surpass these restrictions. the aim of the present work was to evaluate the effect of short - day onion cultivars and band placement of the fertilizer on onion production in alentejo, planted during the autumn. the experiment was carried out at mitra research station of the university of évora and the treatments were: short - day onion cultivars (?spring star? and ?mineutaka?) and fertilizer application method at plantation (broadcasting and banding at 10 cm ± 2 depth, under the crop row). fertilizer banding did not affect root density (cm cm-3) under the crop row, nor onion bulb yield which was 8.3 and 9.0 kg m-2 for ?spring star? and ?mineutaka? respectively. since the studied cultivars presented resistance to waterlogging and low temperature that occurred during the growing season with good production, short - day onion has great agronomical potential for alentejo region. additionally, having in consideration the growing season conditions, water will not be a limiting factor.

Abstract: As baixas temperaturas e o fácil encharcamento da maioria dos solos do Alentejo constituem uma restri o à produ o de hortícolas ao ar livre, no Outono-Inverno. A cebola de dias curtos pode constituir uma op o pela sua capacidade para superar estes constrangimentos. Assim, este trabalho teve como objectivo estudar o comportamento de duas cultivares de cebola de dias curtos, plantadas no Outono e a influência da localiza o da aduba o aquando da planta o. O ensaio decorreu na herdade experimental da Mitra da Universidade de évora e os tratamentos em estudo foram: a cultivar de cebola de dias curtos (“Spring Star” e “Mineutaka”) e o método de aplica o do adubo à planta o (distribui o a lan o e localiza o do adubo numa faixa a 10 cm ± 2 de profundidade, sob a linha de cultura). A aduba o localizada n o afectou a densidade radical (cm cm-3) sob a linha de cultura, nem a produ o comercial de bolbos a qual foi respectivamente para a “Spring Star” e “Mineutaka” de 8,3 e 9,0 kg m-2. Visto as cultivares estudadas terem apresentado resistência ao excesso de água e às baixas temperaturas que ocorreram durante o ciclo, com produ es consideráveis, a cebola de dias curtos apresenta-se como uma cultura com elevado potencial agronómico para o Alentejo. Adicionalmente, dada a época em que é realizada a cultura a água para a rega n o será um factor limitante.

Abstract: Este trabalho teve como objectivo estudar a influência da aplica o de diferentes quantidades de azoto, repartidas por quatro aplica es, na disponibilidade de azoto nítrico no solo, no comprimento radical, na concentra o de azoto nas folhas e na produ o comercial de cebola de dias médios (cv. Gilmar) no Alentejo. O ensaio decorreu na Centro de estudos e experimenta o da Mitra da Universidade de évora e foi delineado em blocos casualizados com quatro repeti es. Os tratamentos consistiram em 4 níveis de aduba o azotada (0, 37, 74 e 111 kg N ha-1), repartidos por quatro aplica es. A disponibilidade de azoto nítrico no solo, o comprimento radical e a concentra o de azoto nas folhas foram avaliados aos 33, 57, 96 e 127 dias após a planta o. A densidade radical (cm cm-3) sob o bolbo e a 4 cm da linha de cultura, nas diferentes datas e profundidades de amostragem, n o foi afectada pelos níveis de azoto. Ao longo ciclo, 65 a 100 % das raízes, em termos de comprimento radical, concentraram-se sob o bolbo e a densidade radical máxima alcan ada foi de 1,88 cm cm-3. A profundidade máxima de enraizamento situou-se entre os 20 e 30 cm, n o ultrapassando os 10 cm de profundidade até aos 32 dias após a planta o. Nas condi es do ensaio, os resultados indicam como recomendável uma aplica o de 30 kg ha- 1 de azoto à planta o e um aumento da quantidade de azoto aplicado (16,2% do total de N aplicado), no início da forma o do bolbo. A produ o comercial aumentou com o nível de azoto, mas as produ es obtidas com a aplica o de 74 kg ha-1 (5,12 kg m-2) e de 111 Kg N ha-1 (6,59 kg m-2) n o diferiram significativamente.

Abstract: this is a time-trend ecological study to analyze respiratory disease mortality rates from 1980 to 2004. the periods before and after influenza vaccination campaigns for the elderly were examined. in the two years after the campaigns (2000 and 2001), mortality rates decreased, followed by a recovery to levels similar to 1999. this trend is observed for both genders after 2002, although the magnitude of average mortality rates in men is higher than in women. this increase is more evident in individuals over 75 years. vaccination coverage grew after 2002, even though there are no age-specific vaccine coverage data, or information about vaccination homogeneity in the community. some hypotheses to explain the inversion of these trends were raised: circulation of others respiratory viruses (syncytial respiratory virus, parainfluenza, adenovirus), after 2002, premature circulation of influenza a virus in 2004 (week 17), environmental factors (pollution and low temperatures), but they were not analyzed in this paper. etiologic surveillance of flu-like syndromes in the community, as the systematic incorporation of environment indicators, and more detailed vaccination coverage information by the epidemiological surveillance system are emphasized.
