Description	In this experiment was watched the progress of making the total polyphenols content in different leveles of fertilizer sulphur in onion during vegetation. In the work we watched also the influence of sulphur fertilization on the antioxidant activity.The content of total polyphenols was estimated using Folin-Ciocalteau reagent. The absorbance was measured at 765 nm of wave length against blank. Antioxidant activity was measured using a compound DPPH (2,2-diphenyl-1-picrylhydrazyl) at 515,6 nm in the spectrophotometer. Our values of total polyphenolic content during vegetation period were in range from 508,16±27.59 to 638,2±12,84. The highest content of total polyphenolics was recorded at the end of the vegetation period (638,32±12.84) in III. sampling (incorporation of sulphur in quantity of 14,6 mg Skg-1soil). This increase was statistically significant (P-value = 2,10-3). The lowest content of total polyphenols was measured in the middle of vegetation period (415,41± 13,32) in II. sampling (inc In this experiment was watched the progress of making the total polyphenols content in different leveles of fertilizer sulphur in onion during vegetation.
