Sugar beet yield and quality level depends on many complex factors, which in turn provide possibly full disclosure of their genetic characteristics potential. By forming sugar beet of proper quality during their growing season it is important to use different measures of agricultural technologies as raw materials inadequate quality recycling does not give economic effect. Plants growth and development processes strengthening and sugar beet a high productivity formation are impossible without external factors influence.

Effective and efficient measures to improve sugar beet potential productivity is creation of a joint agrochemical background and micronutrient foliar application. Foliar fertilization with microelements promotes synthesis in leaves activation, outflow assimilation as a result of their inclusion in sufficient quantity to roots cells biochemical processes, which ensures their normal growth and creating sucrose accumulation capacity (C12H22O11).

In 2010 field research was conducted to determine sugar beet agrophytocenoses optimal parameters and it was found that the best hybrids for extending to November 10 growing season were diploid hybrids Ukrainian ChS 72 and Leopard , which provide stable productivity by optimum plants planting density of 100-110 thousand/ha recommended for this unstable moistening area of the right bank of the central forest-steppes of Ukraine, by the double leaf-feeding in a phase of leaves closure + of 1-1.5 months before harvesting. On field research results based in order to maximize sugar beet plants productivity in unstable moisture areas, it was necessary to conduct a comprehensive experiment that includes the best elements of technology, which has been studied, namely variety - plants density - two shot micronutrients Reacom - plus - beet foliar feeding.

In the research years sowing period and staircase receiving were characterized by moisture small deficiency in the soil, but it almost did not affect on the field germination level which in variations were high and over the years averaged from 86.3% to 87.1%.

Plants uniformity placing in a row observation has shown that the plants placing intervals number in a given interval increases to 3.3% in the variant where was studied Leopard diploid hybrid (58.8% within a given interval), compared with a hybrid Ukrainian ChS 72 (55.5% within a given interval). However, even significant differences in this index, depending on hybrids planting different origin were not.

Under diploid biological forms plants uniformity placement in a row conditions and farming practices complex full use were formed the optimal plants supply area, which contributes to the correct roots formation and strong leaf mass, and ultimately on their productivity affects.

It is established that the average of research years plant density variations before harvesting was optimal for a given area and amounted for hybrid Ukrainian ChS of 101,4-104,3 72 thousand/ha, hybrid Leopard – 101,4-103,9 thousand/ha. There was not density significant difference depending on research hybrids.

Research has found sugar beet diploid forms root yield significant increase by plants double micronutrients foliar application - in closing leaves in a row phase and 1-1.5 months to harvesting. On plants density of 101-104 thousand /ha background and microelements application rate designed for root yield 70 t /ha in the zone of unstable moisture were yield obtained of 56.0 t/ha hybrid Ukrainian ChS 72 and 58.1 t/ha hybrid Leopard.

Both sugar beet hybrids productivity increase ranged from 4.1 (hybrid Ukrainian ChS 72) to 5.2 t/ha (hybrid Leopard) compared with control.

Under the root yield and sugar content increase sugar yield significantly increased in variants, where were spent two times micronutrients foliar application feeding. Thus, in sugar beet hybrid Ukrainian Chs 72 variant with foliar application feeding was 8.8 t/ha, hybrid Leopard – 9.1 t/ha, sugar yield increment – by 0.9 and 1.0 t/ha. There was no significant difference in sugar and gather its gain depending on the hybrids.

Thus, sugar beet agrophytocenoses optimization provided their productivity significant increase. However, under unstable moisture conditions, even with microelements sufficient collateral, high-yield diploid hybrids did not provide a planned productivity - 70 t/ha.
