Abstract

This article presents the data obtained in determining the fractional composition of soybean grains in slightly salty gray–meadow soils and studying their effect on germination. At the same time, the soybean grain had an average of 7.67 mm in height, 6.58 mm in width and 5.51 mm in thickness. Grain height and width remained relatively stable and had a weak degree of variation (7.07-8.11%). It is noted that the height of soybean grain depends more on the biological characteristics of the variety than its width and thickness on the external environment. It was found that there is a weak correlation between the height, width and thickness of the grain and a strong correlation between width and thickness. The effect of fractional composition on the germination of soybeans has also been established. In large fractions, germination was 79%, in medium - 81%, in small-84%, in ultra-small-66%. When dividing soy grain into a large fraction, it is advisable to use sieves with a diameter of more than 6.14 mm, for the medium fraction - 4.9 mm and for the small fraction - 3.65 mm.
