Abstract


In optimal growth and development conditions of plants, ammoniacal salts and nitrates are absorbed in higher quantity than their ability to transform into protein substances. Achievement of a rational system of supplementary fertilization requires setting of the most appropriate combination of fertilizers, the ratio between these epochs and the doses of administration and knowledge of how each variety or hybrid reacts to fertilizers used. The behavior way of carrots on the content of nitrate and nitrite as a response to the experimental factors is different. The highest nitrate content in carrots roots from variant Nantes-sown early- chemical fertilized (17.03 mg/100 g sp) is descending followed, at statistically significant difference, by variant Nantes-sown later chemically-fertilized (15.27 mg/100 g sp). Flakker variety has the lowest content of nitrates into variant with late sown and chemical fertilization 10.85 mg/100 g sp Regarding the nitrite content, the values obtained from each experimental variants, did not exceed the admited norms but they framed between 0,17 and 0,33 mg/100 g s.p.
