The investigation was conducted in order to assess the effect of increasing doses of nitrogen (0-200 kg/ha) combined with constant P2O5 and K2O doses of 100 kg/ha, each on the yield and nitrate (NO3) and nitrite (NO2) content in vegetable crops on the chernozem soil. Yield of garden radish, carrot and beetroot was increased with increasing doses of nitrogen until to 50 kg/ha, at spinach, broccoli and cabbage until 100 kg/ha, at cauliflower until to 200 kg/ha. Nitrate content with increase of nitrogen in fertilization investigated crops was increased at spinach, cauliflower and carrot but at garden radish, broccoli and beetroot was not significant changed. Nitrite (NO2) content at investigated crops fertilization was increased at carrot and beetroot only.
