  The result of sugar beet production is highly effected by the quality and the yield. Those agricultural techniques are very important which can be applied at low cost to improve these parameters. Such an opportunity is to increase sugar yield by foliar fertilization with nutrients and by treatment with bioactive fungicides.
  In my small block trial I examined the effect of the magnesium and strobilurin active ingredients in different combinations and at different application times on the quality and the yield of sugar beet.
  I found that there was a signifficant increase in sugar content on that blocks which were treated with a bioactive ingredient combined with magnesium in the middle of July and on those which were sprayed with bioactive ingredient in August.

  In our small block experiment in randomised blocks, we examined the effect of 6 foliar treatments at 3 different nutrition levels in 2002 on meadow chernozem soil.
  The experiment consisted of 3 blocks, which corresponded to 3 different nutrition levels. The first block was the control, the fertilization rate of the second block was 20 kg ha^-1 N, 40 kg ha^-1 P₂O₅, 120 kg ha^-1 K₂O, on the third block 40 kg ha^-1 N, 80 kg ha^-1 P₂O₅, 240 kg ha^-1 K₂O were applied. We applied magnesium and strobilurin active ingredient (Juwel, BAS 51200), in different combination and with different application dates.
  We found that the foliar treatments with bioactive fungicides significantly influenced the yield and some quality parameters in this field experiment.
