| Resumo: |
The studies of fertilization splitting are necessary specially for the grass succession black oat-corn where N immobilization is very common. Four experiments were carried out in commercial farms under no-tillage, in four counties - Itaara, Santo Ângelo, Júlio de Castilhos and Tupanciretã, all of Rio Grande do Sul, Brazil, with the objective of evaluating the splitting of N application in a corn/black oat crop rotation, during the 97/98 and 98/99 cropping seasons. The N was applied at three times -- pre-planted, starter and sidedressed. The pre-planted applied N for corn, corresponding to total or partial rates that would be sidedressed presented similar results in relation to the sidedress application, however, years of above average rainfall presented N deficiency for corn, reducing yield, which indicates that N application as starter or sidedress is recommended.
