when analyzing the seedling density, it was found that in the schemes where
the seeds were sown along the
furrows with film spreading,
compared with the
options where the seeds were sown in open ground according to the 90x10-1 scheme,
the number of seedlings was 1.7 thousand plants/ha, at the end vegetation period 2.2
thousand plants / ha, with a sowing scheme of 90x (60x30) x12-1, the number of
seedlings was 2.5-3.9 thousand plants / ha, at the end of the growing season 3.5-4.7
thousand. plants/ha, in the scheme 90x(60x30)x15-1
the number of seedlings was
2.2-3.3 thousand plants/ha, at the end of the growing season - 3.0-3.4 thousand
plants/ha, the number of seedlings in scheme (76x38)x8.8-1 amounted to 3.4-4.4
thousand plants/ha, at the end of the growing season 4.7-5.4 thousand plants/ha, and
in the scheme (76x38)x9.7- 1, the number of shoots is 3.2-4.2 thousand plants/ha, at
the end of the growing season it was 4.4-4.8 thousand plants/ha, in the scheme
(76x38)x11.4-1 the number of shoots is 2, 4-2.9 thousand plants/ha, and at the end of
the growing season it was 3.7-3.5 thousand plants/ha.
it was noted that when spreading the film on furrows and sowing seeds
according to the scheme (76x38)x9.7-1, compared with
the options where sown on
open ground according to the scheme (76x38)x8.8-1; (76x38)x9.7-1; (76x38)x11.4-1
weight of 1000 seeds up to 1.3-1.7-1.0 g and technological parameters of fibers, fiber
yield up to 0.4-0.3-0.1%, fiber length on average 0.6 mm, high tensile strength, up to
0.7-0.6-0.3 gk/tex.
it was determined that in the schemes where the seeds were sown along the
furrows with the spread of the film according to the scheme (76x38)x9.7-1 in a two-
row way, compared with the options where the seeds were sown in open ground
according to the scheme 90x10-1, the yield was more than 6,6 c/ha to 13.2 c/ha,
profitability level from 11.9% to 19.4%, compared with
the options with sowing
according to the 90x(60x30)x12-1 scheme, the yield was more than 1.7 c/ha up to
10.6 c/ha, profitability level from 5.0% to 17.5%, compared with the options with
sowing according to the scheme 90x(60x30)x15-1, the yield was more from 3.0 c/ha
to 12.4 c/ha, profitability level from 4.9% to 18.7%, compared with the options with
sowing according to the scheme (76x38)x8.8-1, the yield was more from 0.8 c/ha to
9.9 c/ha, the level of profitability is from 1.8% to 16.4%, compared with the options
with sowing according to the scheme (76x38)x9.7-1, the yield was more from 3.6
c/ha to 9.3 c/ha, the level profitability from 3.6% to 14.5%, compared with the
options with sowing according to the scheme (76x38)x11.4-1, the yield was more
from 2.3 c/ha to 11.8 c/ha, the profitability level was from 1.3% to 14.5%.
