ABSTRACT
The article provides information on the dependence of such indicators of productivity as the number of bolls, the yield
of cotton from one boll and the yield of one boll for various varieties and samples of fine-staple cotton on low-nutrient
desert sandy soils of the river. Termez district of Surkhandarya region on the biology of varieties.
KEYWORDS
Cotton, medium fiber, white fiber varieties and samples, number of bolls, cotton in one boll, number of seeds, weight
of 1000 seeds, yield per bush, average yield.
INTRODUCTION
In our republic, mainly medium-staple (G. hirzutum L)
and partly fine-staple (G. barbadense L) varieties of
cotton are grown. In recent years, fine-staple cotton
has been grown only in the Surkhandarya region. These

two species differ sharply from each other in valuable
economic characteristics and precisely in terms of
productivity. Productivity of a crop of one bush, the
crop is received taking into account the area. it's called
performance. The high yield of cotton depends on such
indicators as the number of bolls, the number of bolls
per bush, the weight of cotton per bolus, the number
of seeds and the weight of 1000 seeds. If these figures
are high, the yield of one bush will be high. Such
varieties and samples have high yields. In addition to
the variety factor, two indicators determine high
productivity. One of them is productivity indicators,
and the other is the number of productive plants per
unit area. Usually, a boll of medium-staple cotton
varieties has a large size, on average 5-6 g, the number
of bolls in fine-staple cotton varieties is a little small,
3.0-3.5 g. It will be. But the number of bolls is high
because the fine-fibre zero-type cotton is tall, and the
branching stem cotton is multi-branched. As a result,
performance will be high. In addition, an increase in the
rate of irrigation and fertilization by agrotechnological
factors has a positive effect on increasing yields.
Fertility
: When plants are grown in a large feeding
area, their bolls are large, the amount of cotton in the
pods is high, and the seeds are also large. Therefore, in
the process of growing elite cotton seeds, a large area
of plant nutrition is 0.6 m of row spacing. 3 bushes per
linear meter, row spacing 0.9 m. 4 bushes are grown in
one linear meter. To obtain a good harvest, 6-8 plants
are grown. The reason is that the quantitative and
qualitative signs of plants grown on a large feeding
area are completely absent. However, productivity is
low due to the small number of plants on the site.
Therefore, 6-8 bushels of cotton are grown per 1 linear
meter for the production of industrial crops. But the
main indicator is the diversity factor. Considering the
above, an urgent issue is the study of productivity
indicators of new promising varieties and accessions of
fine-staple cotton with a low supply of nutrients.
MATERIAL AND METHODS
Field experiments. It was held on the basis of the
educational and experimental farm of the Termez
Institute of Agrotechnologies
and Innovative
Development. The experimental area is a desert, sandy
soil with a very small supply of nutrients. In the field
experiment, we used 2 reproductive seeds of G.
barbadenze L. of the species Surkhan-16, Surkhan-103,
Termiz-202, Yolatan-14, Termiz-111 with fine fibers.
Experimental plot (4 rows, row spacing 0.6 m, length
30 m). Experimental area (4 x 0.6 x 30) 72 sq.m. Field
experience is divided into two levels and consists of
four returns. As a model for evaluating the studied fine-
fiber varieties, the Surkhan-14 variety, recommended
for planting on the territory of the republic and planted
on the main fields in the Termez region, was used.
The studies were carried out according to the OZPITI
(2007) and generally accepted methods.
RESEARCH RESULTS
According to the data obtained in the experiments, the
number of bolls in one bush is from 16.5 to 21.4 pieces,
the weight of one cotton boll is from 3.0 to 4.1 g, the
number of seeds in one boll is 32.0. It was found that
37.0 seeds and 1000 seeds have different weights from
117 to 125 grams. It should be noted that the number of
pods in varieties Surkhan-103 and Termez-111 was very
high compared to other varieties, from 19 to 21 per
bush. It was noted that the number of seeds in one
bean in these varieties is 3-4 more than in the model
variety (Surkhan-14). Length 37 mm. micron -4.3-4.4,
relative density 35 gk/tex and fiber length 1 mm has 9-
10-fold curl, these varieties are studied as high-quality
fiber-giving, high yields, blueberries in 1 bush - 18.6.

pieces, the weight of cotton in 1 bag is 3.6 g, the
number of threads is 35.3 DNA, the weight of 1000
threads is 120 g. The yield of the Termiz-202 variety,
which has a high yield index, was 33.2%, while it was
found that the yield of this variety is 0.6 t/ha less than
that of the model variety (Surkhan 14).

Productive indicators of samples of fine-staple cotton of different varieties
CONCLUSION
The productivity indicators of fine-fiber cotton
varieties are different on desert sandy soils with very
low nutrient supply in the Termez district of the
Surkhodarya region. The Termiz 103 variety and the
Thermi-111 sample, which have high productivity
indicators, have high productivity, as well as high fiber
quality indicators.
