          Abstract

          Foram realizados ensaios de laboratório com amostras de sementes obtidas de dois experimentos em campo, no município de Pindorama, de maio a agosto, em 1992 e 1993, visando estudar o efeito do nitrogênio e de micronutrientes, aplicados sob várias formas,  na qualidade das sementes do feijoeiro cultivar IAC-Carioca. Tomaram-se amostras de sementes de cada tratamento aplicado em campo, acondicionando-as em sacos de papel e conservando-as em câmara seca com temperatura de 15o C e umidade relativa do ar de 40%, sendo efetuados testes de germinação imediatamente após a colheita e após 12 e 24 meses. Os resultados foram analisados e as médias, comparadas pelo teste de Duncan:tanto o fornecimento diferencial de N como o de micronutrientes não afetaram a qualidade fisiológica das sementes, medida por meio da percentagem de germinação e de plântulas anormais, não se observando acúmulo ou déficit de elementos nutrientes nas sementes do feijoeiro.

          Translated abstract

          Germination tests of cv. IAC Carioca were conducted with seeds from two field experiments in 1992 and 1993. Nitrogen and micronutrients, were applied in the yield various forms and the quality of seeds was assessed. Seed samples were packed in paper bags and maintained in a cold dry chamber at a temperature of 15o C and 40%relative humidity. Germination tests were conducted immediately after harvest and 12 and 24 months of storage. The data were analyzed by comparing the average by the Duncan test. The results showed that the different sources of N and micronutrients did not affect the quality of seeds and that there was no excess or deficiency of nutrients in the dry beans seeds.
