INTRODUCTION
Onion is a species of the Alliaceae family (Allium cepa
L.) and is used to improve the digestive system, as a
medicine for first degree burns and respiratory
problems. The origin of the onion, whose origins go
back many years, has also found its place in the
Egyptian pyramids [4].
Onion is a two-year plant that produces bulbs in the
first year and seeds in the second year. 100 g of onion
contains 1.2 g of protein, 0,1 g of fat, 8,9 g of sugar, 8 g
of water, 12 g of dry matter, 30 mg of calcium and 42
calories [2].
In our country, onion is second only to tomato in terms
of area and yield. Its share among vegetable crops is
23-24%, 18-19% of the gross product, and the average
productivity is 50-60 tons per hectare [1].
Onions grow well in short light days (10-12 hours), but
in such conditions, nutrients are not transferred to the
reserve (do not circulate), the onion head does not
form, the plant does not enter the dormant period, and

the onion remains in the state of a thick false stem. It is
important to know this characteristic of onion for the
length of the day in choosing a variety and carrying out
quality agrotechnical activities [3].
A new variety of onion, Phule safed, developed at
Raguri station, India, has higher yield (24,59 and 25,75
t/ha) than the popular variety N-257-9-1, which is grown
in large areas, and 7,29 and 5,71 t/ha, respectively gave
the product [5].
Onion varieties belonging to different ecological types
(in the USA, Iran and Egypt) were tested by planting
seedlings in 1 term (seeds were planted on March 18,
seedlings were planted on May 6) in the geographical
latitude of Moscow [7].
In the following years, the Ravnaq and Bahoroy
varieties of onion were created, based on their
biological characteristics, the issues of agrotechnics
and seed production, and the organization of these
activities through resource-efficient and intensive
technologies, are not scientifically based [6].
Based on this, the development of the biological
characteristics of these varieties, their production and
seed technology is one of the important tasks of
modern vegetable farming.
Research methods. The research was conducted in
field conditions, using the "Methodology of
conducting experiments in vegetable growing, potato
growing and potato growing".
Research results. The experiment was carried out in
two different (Sariosiyo and Bandikhon) districts of
Surkhandarya region on 20 plots of 1 ha. Karatol onion
seeds were used as seed material in the experiment.
The seed germination rate was 95% and the weight of
1000 seeds was 3.2 g. The experiment was carried out
using the observation method.
200 kg/ha of phosphorous fertilizer (Ammafos) was
given to the experiment area before planting seeds
(03.01.2022). The field experiments were carried out
under the following conditions: in the experiment in
Bandikhon district, the egates with a row spacing of 60
cm and a ditch depth of 12 cm were taken and placed
on 03.03.2022. The amount of sown seeds was 5 kg. In
the experiment in the Sariosia district, the rows with a
row spacing of 50 cm and a ditch depth of 12 cm were
taken and placed on 10.03.2022. The amount of sown
seeds was 5 kg. Daily weather data was observed and
recorded in a notebook from the day of sowing the
seeds until it was ready.
Phenological observations: The first observations were
made 10 days after sowing the seeds, the second after
50 days, and the third after 80 days. During the
observation, seed germination, development, leaf
length, surface, and bulb size were monitored (Table
1).

When the observation results were analyzed, the germination of our seeds planted in both districts did not differ from
each other, but as a result of the sudden rise in the weather in Bandikhon district, the level and length of the leaves
did not reach a sufficient level, and the size of the onion heads did not reach the expected 2-3 caliber (Table 2).

Looking at the results in Table 2, the heat level in
Bandikhon district increased sharply from the second
half of April, which had a negative effect on the growth
of onion heads. In the Sariosia district, the size of onion
heads was 2-3 caliber due to the fact that the weather
temperature remained at the same level and the
amount of precipitation was high.
CONCLUSION
In conclusion, it is worth mentioning that onion
cultivation is one of the most urgent tasks in our
country. It was observed that heat level is important in
our field experiments in Bandikhon and Sariosiya
districts of Surkhandarya region. In other words, it was
determined that the temperature between 20-25oC is
important for the onions to ripen and be ready.
