Table 1. Results of studying the mass of 1000 seeds
For example, the coefficient of variation of the mass of 1000 hairy seeds is 1.73%, while the
coefficient of variation of the mass of 1000 treated seeds is 0.27%, that is, the coefficient of
variation of 1000 treated seeds is the same as that of hairy seeds. is decreasing by 6.4 times.
Therefore, processing hairy seeds with compounds that protect and nourish seeds allows
obtaining seeds close to each other in terms of mass [11-15].
Table 2 shows the results of the study of the geometric dimensions of hairy seeds and
processed seeds.

As can be seen from the results presented in the table, the geometric dimensions of the hairy
seed were also changed when processed. For example, if the average length of hairy seeds is
α = 9.59 mm, after processing, their average length is α = 11.01 mm, that is, the length of
processed seeds is hairy seeds. 1.42 mm increase compared to that of seeds.
A similar pattern was observed for the width and thickness of processed seeds. In particular,
the width and thickness of processed seeds are increased by 0.34 and 0.30 mm, respectively,
compared to those of hairy seeds.
It should be noted that the processing of hairy seeds allows obtaining seeds close to each
other in terms of geometric dimensions.
Table 3 shows the results of the study of the friction angles of hairy seeds and processed
seeds.

As can be seen from the results presented in the table, changes in the mass and geometric
dimensions, as well as the angle of friction, were observed when the hairy seeds were
processed. For example, if the friction angle of hairy seed seeds is on average φ=33º28r, after
processing their friction angle is on average φ =22º16r 22º16r, that is, the friction angle of
processed seeds is hairy seed compared to that of seeds decreased by 11º12r. In other words,
the dispersibility of processed seeds increased by 1.5 times compared to the dispersibility of
hairy seeds. This is of great importance for planting hairy seeds with a low level of precise
nesting [16-20].
From the results of the study of some physical and mechanical properties of processed hairy
seeds, the following conclusion can be made: when processing hairy seeds, seeds that are
close to each other in terms of mass and geometric dimensions are obtained. , dispersion and
granularity increase, and it is possible to plant them accurately at low rates.
