INTRODUCTION
It is known that increasing the productivity of
agricultural crops, including cotton, accelerating the
harvest and improving the quality of fiber is one of the
most important issues facing scientific production. In
this regard, one of the great achievements in the field
of science and technology in our time is the discovery
and creation of optical power generators-lasers.
The effectiveness of laser irradiation before planting
seeds was recorded in experiments conducted in
different growing regions. The "Termiz-14" variety
achieves the highest yield in 15-20 minutes of exposure,
5-7 times of irradiation. Irradiation of seeds has a
therapeutic
effect
on
uniform
germination,
development and growth of seedlings. In the
conditions of the southern desert zone of the
Surkhandarya region, the effect of laser irradiation on

germination, growth, and productivity of "Termiz-14",
"Termiz-16" thin-fiber cotton varieties before planting
is being studied for the first time.
The procedure of irradiation for the purpose of
selection differs from the procedure of irradiation for
the purpose of increasing productivity. It is necessary
to carefully select the irradiation method for each crop
and analyze many years of generations. The results of
experiments conducted on some vegetables and grain
crops show that it is desirable to carry out wider and
deeper researches in laboratory and production
conditions.
The data obtained from the experiment carried out by
the scientists of our republic showed that seed
irradiation in such varieties as "Druzhba-60", "9647-I",
"Sharof-81" has a significant effect on the
technological properties of the fiber. Currently, as a
result of research, it was found that "9647-I", "Drujba-
60" varieties are more sensitive to radiation than other
cotton varieties. When the seed was irradiated, the
fiber thickness and breakage rate of all types of cotton
decreased and the strength increased significantly. It
should also be mentioned that the fiber length of
"Sharof-81" variety increases significantly under the
influence of laser light.
Irradiation of thin fiber cotton seeds "Termiz-14",
"Termiz-16", "9871-I" will be carried out in March and
early April from 2015 to 2020 in the laboratory of the
physics department of Termiz State University.
In our experiment, when the dynamics of cotton
seedlings were studied. The seeds of "Termiz-14" and
"Termiz-16" varieties are naturally hairless, and there is
a significant difference in germination depending on
the period of irradiation of the seeds. By April 30, 76.1
percent of non-irradiated seeds will germinate, and
81.7 to 86.0 percent of irradiated varieties will
germinate. Among the options studied, the best result
was achieved when the seed was irradiated from 10 to
40 minutes, even 83.1-85.5 percent.
It is necessary to mention that in all the options where
the seed was irradiated, the seedling germinated and
developed in a uniform thickness compared to the
usual one. It should be recognized that in the varieties
that were irradiated for 40 minutes and seven times,
the seedlings germinated with a uniform thickness
compared to the normal and all other varieties.
However, it usually did not exceed 79.5 thousand per
hectare. Observing the state of the cotton before
starting to harvest shows that the long and short
period of seed fertilization has different effects on the
structure of the cotton.
(Table 3)
The results of experiments conducted on cotton
showed that seed irradiation before planting has a
positive effect on the opening of bolls. The number of
opened pockets was from 18.5 to 23.2 units, depending
on the options. The seeds opened 1.0-4.7 more pods in
the irradiated options compared to the control.
Thus, laser irradiation of "Termiz-14" and "Termiz-16"
fine-fiber cotton seeds before sowing has a positive
effect on the germination of seeds with a uniform
thickness compared to the usual one, good growth and
development of the plant.
Our experiments showed that laser irradiation of
cotton seed with thin fibers has a positive effect on its
germination, stalk thickness, plant growth and
development, and ensures high cotton yield. (Table 4)
The yield was higher in all variants where the seed was
irradiated with laser compared to the control. The
highest cotton yield was obtained in 30.40 minutes in

CONCLUSION
In conclusion, it can be said that in "Termiz-14" and
"Termiz-16" thin-fiber cotton varieties, laser irradiation
of seeds before planting has a positive effect on
seedling germination, growth and development,
productivity. In places where fine fiber cotton is
planted, this event will speed up the harvest and
increase the weight of the first harvest cotton. It was
observed that the technological quality of cotton fibers
improved slightly when lasered before seeding.
