Özet

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.
