This study was conducted to determine the effects of nitrogen (0, 120,
and 240 kg N ha(-1)) and phosphorus (0, 90, and 180 kg P(2)O(5) ha(-1))
doses on some tuber quality traits of the potato cultivar Agria under
the ecological conditions of Erzurum in the years 2005 and 2006. The
effects of N levels were significant only on the protein content of
tubers while the P levels only significantly affected the oil content of
the crisps. No significant N x P interaction effects were found on any
of the traits evaluated. Based on these results, it could be concluded
that the potato crop should be fertilized with 120 kgha(-1) N and that
phosphorus fertilizers should be added when soils are P deficient in the
Erzurum region.
