Dzyubenko, I. | Ermantraut, E.
In a field experiment (2011-2013) we studied the effect of foliar fertilization on the yield of modern sugar beet hybrids of Ukrainian selection and we established the optimal harvesting dates for the conditions of right-bank forest-steppe of Ukraine. The obtained results showed that foliar feeding with microfertilizers (Reakom, Tseovit, Rostok) provides an increase in root yield of hybrids(Alexandria, Romulus, Kvarta, Zluka) by September 1 2,3-6,6 t/ha, September 20 2,8-8,1 t/ha, October 10 - 2,6-7,0 t/ha. Sugar content of roots was increased on September 1 by 0,9-1,4%, on September 20 by 0,8-1,7%, on October 10 by 1,2-1,8%, sugar yield gain on September 1 was 1,1-1,9 t/ha, on September 20 - 1,3-2,3 t/ha, on October 10 1,6-2,4 t/ha in comparison with the control variant. The transfer of harvesting dates from September 1 to October 10 provides an increase of root yield from 4,5 to 6,7 t/ha, beet sugar content increases by 1,0-1,9%, and the yield of sugar - 1,5-2,2 t/ha.
