    The Nitrate and Nitrite Levels of the Tubers of Potato Plant Fertilized With Different Doses
    (Scientific Technical Research Council Turkey, 1999) Aksoy, A; Türel, I; Arslan, B; Dede, Ö
    In this research,,This study was conducted to determine the effects of nitrogen forms (ammonyum nitrate, ammonyum sulphate and urea) and nitrogen doses (0. 7, 14, 21 and 28 g/m(2)) on nitrate and nitrite levels in potato cultivars (Caspar and Kondor). It was found that the levels of nitrate and nitrite obtained from the experiment did not exceed the accepted tolerance limits of 300 mg/g. However, differences among cultivars and nitrogen doses were found to be significant (p<0.05 and p<0.01, respectively) in terms of nitrate levels. The lowest nitrate levels were found in the caspar cultivar and the control. On the other hand, differences among nitrogen forms were found to be significant (p<0.05) in terms of nitrite levels. The highest nitrite levels was determined in ammonyum sulphate (27.67 ppb).
