Özet:

 

Two field trials  FieldExp1 and FieldExp2  and a pot experiment  PotExp  were c0onducted over a period of 3 years to assess  olive tree response to nitrogen  N  applications and to estimate apparent N recovery. FieldExp1 was installed in a 3-year-old olive grove.  FieldExp2 consisted of a plantation of young rooted plants. Two treatments were applied in both experiments: N application and a  nonfertilized control. In PotExp, 4 N rates were used. In FieldExp1, olive yield significantly increased with applied N in only 1 of the  3 growing seasons. In FieldExp2, aboveground dry matter yield significantly increased with N application. In PotExp, total dry matter  yield displayed a typical saturation curve in response to N rates. The poor response of olive yield to N application might be due to the  reduced amount of N removed in the crop, and also to the negative interaction found between N application and water deficit. Apparent  N recovery reached values varying from 13.1% in FieldExp2 to ~100% in PotExp. The results indicate that the olive response to N and N  use efficiency seem to be influenced more by the agroecological conditions defining target yield and N loss, rather than by plant species.
