The following combinations of experiments were arranged: (1) control - without foliar nutrition, and foliar nutrition with: (2) urea, (3) solution of urea+Mo, (4) urea+Mo+BA (benzyladenine BA), (5) urea+Mo+BA+sucrose, (6) BA in the concentration of 5 mg·dm-3 and (7) BA in the concentration of 10 mg·dm-3. In combinations 2-5 the following concentrations of components in solutions were applied: urea and sucrose each in 20 g·dm-3, molybdenum 1 mg·dm-3, benzyladenine 5 mg·dm-3. Foliar nutrition was applied three times. In both years of study the greatest mass of storage roots and whole plant (haulm + root) was determined after spraying with benzyladenine in 5 mg·dm-3 concentration.
