In modern nutrition, bioactive materials of different vegetables are especially important to be researched. The experiment was carried out on March 30, 2016 (sowing date). Mineral element content (B, Ca, Cu, Fe, K, Mg, Na, P, S, Zn) was evaluated on the 60th, 85th and the 105th day of the vegetation period. The data are presented as the mean of five varieties which can give the real state of these parameters of beetroot grown on lowland chernozem soil.

In the young beetroot leaves (60 days) the mineral element content was higher than in the older ones (85 days). The calcium and magnesium content of the leaves was much more favourable (10 times higher) than in the root. The potassium content of leaves has reached the amount of 5000 mg kg-1, but at the same time more than 3000 mg kg-1 was detected in the improved root. This value is favourable for the potassium supply of the human organism.

The sulphur content (1300 mg kg-1) of the leaves was the highest on the 85th day of vegetation period. Similar tendency was detected for boron content (2.45 mg kg-1), while for iron content it was higher (28.23 mg kg-1) in the younger leaves (60 days).

Finally, it can be concluded that the increased element content of beetroot leaves will be a favourable source of mineral element supply of the human organism.
