Influence of water insurance upon technological qualities of root crops of sugar beet of various life-forms

Abstract

Goal. To investigate the influence of different modes of moisture provision on the formation of technological qualities of sugar beet root crops of different breeding origin. Methods. Vegetative, laboratory, statistical. Results. On the basis of the analysis of the research results, the influence of three modes of moisture supply of the soil - 45, 60 and 75% of the total field moisture content (PPV) on the formation of technological qualities of beet sugar of different breeding origin during the harvesting period was revealed. Conclusions. For increasing the level of soil moisture from 45 to 75%, the technological yield of sugar beet sugar varieties and hybrids of various biological forms (R2 = 0,93 - 0,99) increases due to the increase in the mass of root crops. However, it is advisable to determine the optimal conditions for moisture provision separately for each grade or hybrid.
