PRODUCTIVITY AND QUALITY OF WINTER WHEAT VARIETIES IN THE EASTERN PART OF THE ROSTOV REGION

Abstract

Productivity of winter barley varieties is a main characteristic for their wide introduction into agricultural production. Yields and quality of grain are usually formed under influence of a complex set of conditions. Grain productivity depends on such factors as cultivation technology, hydrothermal regime, tolerance to unfavourable weather conditions. Plant moisture supply is the main factor for obtaining high yields of winter barley in the eastern part of the Rostov region. The study was conducted in the years of 2014-2016, which were characterized with different moisture supply. There were studied the varieties ‘Master’, ‘Tigr’, ‘Timofey’ and ‘Erema’ developed by the FSBSI ARC “Donskoy”. On average three varieties ‘Master’ (4.26 t/ha), ‘Timofey’ (4.18 t/ha) and ‘Erema’ 4.37 t/ha) gave the largest yields for three-year period of study. On average for three-year period of study the greatest quantity of protein was found in the variety ‘Tugr’ (11.7%), the greatest amount of starch was found in the variety ‘Timofey’ (59.2%).
