Shyrokostup O. Improvement of intensive production practices for sugar beet in Right–Bank Forest–Steppe

The dissertation presents a theoretical justification and experimental results of solving important scientific tasks to improve elements of intensive technologies of cultivation of sugar beet in the Right Bank Forest-Steppe of Ukraine. The research resulted in a adaptive technology that ensures the formation of beet roots productivity from 64,5 to 78,9 t/ha through the use of new highly disease–resistant domestic hybrids and farming practices and reducing costs by 21,2 % due to minimizing production steps as well as reducing chemical loads through the use of new formulations at the minimum application rates. For timely adjustment of nutrition regime in sugar beet, foliar application of microelements in the first and second half of the growing season is needed in the way of successive spraying minimum rate micronutrients. Longer growing season of sugar beet in the autumn when applying foliar feeding in two or four consecutive sprays of micronutrients promotes developing potential productivity of the crop.The proposed system of weeds control in sugar beet does not imply inducing chemical stress in plants and comprises increasing the number of consecutive sprays of herbicides at the minimum application rates. It was found that in the Right–Bank Forest–Steppe zone of Ukraine, increased number of consecutive sprays of fungicides Falcon 460 ES Alto Super 330 ES, KE, Impact 500 CS, Cercostef SC to four sprays provided saving 59,9 ton/ha of roots. Sugar content in roots in this treatment was 16,8 %, conductometric ash content of 0,93 %, and sugar yield of 10,1 t/ha.
