INTRODUCTION
Today, in solving the food problem of the
population of our country, it is important to
prepare seedlings of sweet pepper varieties with
high quality, high transportability and resistance to
diseases. Sweet pepper is unique compared to
other vegetable crops, its fruit can be eaten both
when it is blue and red, and its fruit is rich in
vitamins A and C.
The average production of pepper in our republic
is 270-280 thousand tons, most of which is
exported abroad. In terms of biochemical
composition, nutritional value, transportability
and shelf life, sweet pepper is significantly different
from other vegetables. According to the amount of
dry matter (14.5%), it ranks first among vegetables
(after garlic), and according to the amount of
vitamin “C” (ascorbic acid). Sweet pepper fruits
grown in our country contain 54-118 mg/% in the
period of technical ripening, and 368-535 mg/% in
the period of physiological ripening of vitamin “C”
[1].
Under certain conditions, the possibility of
increasing the production of sweet pepper is to
expand the cultivated areas and increase the yield.
The main way to increase productivity and obtain
products suitable for export is the correct selection
of adaptive, high-yielding varieties, improvement
of agricultural cultivation technology, in particular,
rational use of organic and mineral fertilizers and
growth stimulants. [1,2].
In the conditions of irrigated light gray soils of
Kashkadarya region, it is recommended to use
organo-mineral fertilizers in order to obtain a high
and stable market yield (32-35 t/ha) from sweet

pepper variety “Dar Tashkent”. 20 t/ha manure +
N200P160K100 kg/ha and treatment with
solutions of growth stimulants during the
flowering period (gibberellin 0.6-0.7 g per 10 liters
of water).[7]
The seedling method has a number of advantages
over the conventional method of sowing seeds
directly into the ground. Seedlings are usually
grown for 30-80 days. The achieved progress in
plant development allows early harvest. Selling
early harvest at higher prices provides additional
income. Thanks to the advance, the seedling
method allows you to extend the growing season.
This increases plant productivity and makes it
possible to grow heat-loving crops and enrich the
variety of vegetables in the northern regions,
where the growing season is long, but there is not
enough heat, and there are no conditions to collect
the harvest from seeds. The seedling method
reduces the need for land at the beginning of the
plant's life. Better provision of plants with food,
moisture, heat, light and other factors, better
protection of still weak seedlings from pests,
diseases, and weeds, can reduce labor costs in the
fight against them. In the seedling method, seed
consumption is reduced by 3-7 times compared to
planting in a permanent place. Cultivation of plants
through seedlings in protected ground conditions
extends the product release period and provides an
opportunity to use artificial lighting sources
economically [7].
Accordingly, we focused on this type of crop in our
research.
The main goal of the research is to grow sweet
pepper seedlings of high-quality, disease-resistant,
highly transportable varieties.
Taking this into account, experiments were
conducted in laboratory conditions on a special
peat substrate.
METHODS
In the experiment, the seeds were collected in a
thermostat at 250C for 3 days, and then on January
10, they were planted in special cassettes as a
substrate in peat with a pH of 6.5-7.0. On January
20, seedlings were transplanted into special peat
containers with a capacity of 200 ml during the
period of two full blooms, then the seedlings were
watered, and the humidity was kept at 70-80%
MPV. 6 options were used for planting seedlings,
i.e. option 1 - control; Option 2: N18P18K18 kg/ha;
Option 3: N36P36K36 kg/ha; Option 4:
N54P54K54 kg/ha; Option 5: N72P72K72 kg/ha;
Option 6: N90P90K90 kg/ha was used. From
mineral
fertilizers,
NPK
fertilizer
18:18:18+3MgO+ME or azofoska was used. 10, 20,
30, 40, 50 grams were applied to 10 l of distilled
water.
Research was conducted in laboratory conditions.
All records, observations, analyzes and calculations
in the experiment were conducted based on
generally accepted methods and agricultural
recommendations [3,4,5].
RESULTS AND DISCUSSION
According to the results of the study, when
analyzing the growth and development of sweet
pepper varieties “Bella Vista”, “Kalota” and
“Dar
Tashkenta” in 6 options and 3 returns, the survival
rate of seedlings in the experimental options on the
5th day after planting is 100 percent it was
determined.
The use of mineral fertilizers tends to increase the
survival rate of seedlings. When the seedlings of
the plant form 5-6 true leaves, the biometric
indicators are analyzed in the section of the
varieties. Before planting in the field, in the 1st
experiment (“Bella Vista” variety was planted), in
the control option, the plant height is 6 cm, the
number of leaves is 6 pieces. , in the 2nd
experiment (the Kalota variety was planted) the
plant height was 5.5 cm, the number of leaves was
7 pieces, in the 3rd experiment (the Dar-Tashkenta
variety was planted) the plant height was 8 cm, and
the number of leaves was 8 pieces reached, the
highest superiority in variant 4 (N54P54K54)
compared to the control, in accordance with the
above, plant height 2 cm in experiment 1. ha, the
number of leaves is 3.5 pieces, 2 - in the
experiment, the plant is 1 cm tall. ha, the number of
leaves is 3.5, and in the 3rd experiment, the plant is
2 cm tall. ha, if the number of leaves was 2 more,
the relatively highest indicator was returned in 5-6
options. The lowest indicator was found in variants
2 and 3.

When these varieties were analyzed not only in the
section of variants, but also among varieties, the
“Dar Tashkenta” variety prevailed with all variants.
The “Kalota” variety took the second place after the
“Bella Vista” variety.
CONCLUSION
The seeds of medium-quick ripening varieties of
shirin qalanpir were grown in 200 g plastic
containers with soil + peat substrate. When
observations were made in all varieties, compared
to the control option, the highest advantage in
terms of plant height, joint spacing, number and
level of was returned in options 4, compared to
essa 4. - Observed in 5 options. It was found that
the lowest indicator is in 2-3 options.
