The Effects of Different Nitrogen and Phosphorus Rates on Some Quality Traits of Potato
Tóm tắt
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 P2O5 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 × 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 kg ha−1 N and that phosphorus fertilizers should be added when soils are P deficient in the Erzurum region.
