Introduction.
Among agricultural crops, potatoes are considered the daily food product
consumed by the population. Therefore, it is grown annually in the world on an area of 18-19
million hectares, yielding 3.1-3.3 million tons. In world agriculture, it is the second largest
agricultural crop after wheat, rice, and corn in terms of area, and in terms of importance, it is
used to prepare more than 500 different dishes.
Potatoes are considered the second bread among the population due to their high
consumption. One of the main reasons for this is that potato tubers are rich in nutrients necessary
for the human div - starch, protein, sugar, fiber, various vitamins, and mineral elements.
Among the European, Asian, North American, South American, African, and Oceanian
continents growing potatoes in the world, the countries of the European continent are in first
place, and in terms of potato cultivation - the sown area is 9145 thousand hectares, and the gross
harvest is 138.2 million tons.
According to the Food and Agriculture Organization of the United Nations (FAO), global
potato production could double within 10 years, making a significant contribution to global food
security. By focusing on increasing yields and fully utilizing historical potato fields, global
production could reach 500 million tons by 2025 and 750 million tons by 2030. (FAO report
2023).
In Uzbekistan, potatoes have been grown mainly for food purposes for 160 years.
Potatoes are grown by farmers, agricultural clusters, and household plots.
Population growth, limited land and water resources used in agriculture. Therefore, in our
country, with the rational use of opportunities, in order to provide the population with high-
quality food products and develop product exports, great attention is paid to sowing repeated
crops in areas freed from grain.
In order to develop this industry, the Resolution of the President of the Republic of
Uzbekistan dated May 6, 2020 No. PP-4704 "On measures to expand potato cultivation and
further develop seed production in the republic" was adopted. In accordance with the resolution,
special attention is paid to increasing the production of consumer and seed potatoes in the

value-added chain in the industry based on modern technologies, meeting the demand of the
domestic market, expanding its exports, growing super-elite and elite generations of seed
potatoes on 50 percent of sown areas, and widely introducing advanced technologies, innovative
solutions, and scientific achievements.
The aim of the research is to improve integrated control measures against weeds on
potatoes planted as a repeated crop in the conditions of meadow-saz soils of the Fergana region.
The scientific novelty of the research is as follows: for the first time, the influence of
combined weed control on weeds in potato fields planted as a repeated crop in the conditions of
meadow-bog soils of the Fergana region has been determined;
The influence of combined weed control on the agrophysical, water-physical, and
agrochemical properties of the soil in potato fields sown as a repeated crop is determined;When
cultivating potatoes grown as a repeated crop, various methods of soil cultivation and the
application of herbicides have a positive effect on the growth, development, yield, and quality
indicators of potatoes;

compared to plowing to a depth of 25-30 cm with a two-tier plow in autumn, the degree of weed
infestation of plants with conventional (single-tier) plowing increased by 2.5 times (31%).
The current period of development requires accelerating agriculture with innovative
technologies, strengthening the fight against weeds, and improving control methods. In reducing
weed damage, combined use of herbicides along with various soil cultivation methods creates
the possibility of their complete elimination.Taking these circumstances into account, when
implementing integrated control measures against weeds, in order to determine the effectiveness
of the use of herbicides along with the main soil tillage methods on weeds in potato fields
planted as a repeated crop, the number of weeds was taken into account before the main soil
tillage and surface tillage.
The obtained data (2024) show that when taking into account the number of weeds in the
field before soil cultivation with a conventional plow to a depth of 28-30 cm, the number of
annual weeds was 28 units/m2, while in perennial weeds this indicator was 23 units/m2. In
summer (2024), taking into account the number of weeds before surface tillage on this
background, it was noted that the number of annual weeds was 13 units/m2, and the number of
perennial weeds was 13 units/m2.
When taking into account the number of weeds in the field before plowing to a depth of
28-30 cm with a two-tier plow, the number of annual weeds was 29 units/m2, while in perennial
weeds it was 22 units/m2. In summer (2024), when taking into account the number of weeds
before surface tillage on this background, it was noted that the number of annual weeds was 9
units/m2, and the number of perennial weeds was 8 units/m2.
As can be seen from the obtained data, when plowing with a two-tier plow to a depth of 28-30
cm, compared to soil tillage with a conventional plow to a depth of 28-30 cm, the germination of
annual weeds was 4 units/m2, and perennial weeds - 3 units/m2.
Based on the above data, it can be concluded that plowing with a two-tier plow to a depth
of 28-30 cm, compared to soil cultivation with a conventional plow to a depth of 28-30 cm, leads
to the burial of weed residues and seeds in deep layers, which explains the low germination of
their seeds and rhizomes (Table 4.1).
In our study, in order to study the effectiveness of the combined use of herbicides during
the growing season of potatoes in combination with basic soil tillage against weeds, the number
of weeds in all variants of the experimental plot was taken into account after 20, 40, and 60 days.
According to the data obtained from the observations, in the control variant, where the
soil was cultivated with a conventional plow to a depth of 28-30 cm and herbicides were not
used against weeds, in our first observation, a one-year experiment was conducted.The number
of annual weeds was 21.45 units/m2, the number of perennial weeds was 14.40 units/m2, in the
variant with the application of the herbicide Dafosat at a rate of 4.0 kg/ha with sowing, the

number of annual weeds was 20.45 units/m2, perennials - 13.85 units/m2, in the variant with the
application of the herbicide Ridovn Xtra 75% at a rate of 2.0 kg with the emergence of 2-3 true
leaves, the number of annual weeds was 21.15 units/m2, perennials - 14.55 units/m2.
In the control variant with plowing with a two-tier plow to a depth of 28-30 cm and
without the use of herbicides against weeds, in our first observations, the number of annual

with the application of the herbicide Dafosat at a rate of 4.0 kg/ha with sowing, the number of
annual weeds was 16.40 units/m2, and perennial weeds - 11.70 units/m2, in the variant with the
application of the herbicide Ridovn Xtra 75% at a rate of 2.0 kg with the emergence of 2-3 true
leaves, the number of annual weeds was 16.85 units/m2, and perennial weeds - 12.20 units/m2.
In the experiment, in order to determine the effectiveness of soil tillage methods against
weeds and the combined use of herbicides, after 20 days, in the control variant with soil tillage
with a conventional plow to a depth of 28-30 cm and without the use of herbicides against weeds,
the number of annual weeds increased by 28.20 units/m2 (32.5%), and the number of perennial
weeds increased by 16.80 units/m2 (18.6%), in the variant with the application of the herbicide
Dafosat at a rate of 4.0 kg/ha with sowing, the number of annual weeds decreased by 6.65
units/m2 (67.2%), and perennial weeds by 3.75 units/m2 (73.2%), in the variant with the
application of the herbicide Ridovn Xtra 75% at a rate of 2.0 kg with the emergence of 2-3 true
leaves, the number of annual weeds decreased by 4.60 units/m2 (77.7%), and perennial weeds
increased by 15.30 units/m2 (5.1%).In the control variant with plowing with a two-tier plow to a
depth of 28-30 cm and without the use of herbicides against weeds, the number of annual weeds
increased by 20.80 units/m2 (23.8%), and the number of perennial weeds - by 23.8%.
In the variant with the application of the herbicide Dafosat at a rate of 4.0 kg/ha with
sowing, the number of annual weeds decreased by 4.70 units/m2 (73.9%), perennial weeds by
2.30 units/m2 (82.0%), and in the variant with the application of the herbicide Ridovn Xtra 75%
at a rate of 2.0 kg with the emergence of 2-3 true leaves, the number of annual weeds decreased
by 2.60 units/m2 (84.1%), while the number of perennial weeds increased by 12.63 units/m2
(3.6%).
In order to account for weeds in the experiment, we conducted a second observation after 40
days.The obtained results show that in the control variant with soil cultivation with a
conventional plow to a depth of 28-30 cm and without the use of herbicides against weeds, the
number of annual weeds increased by 28.95 units/m2 (35.0%), and the number of perennial
weeds by 17.20 units/m2 (21.8%), in the variant with the application of the herbicide Dafosat at
a rate of 4.0 kg/ha with sowing, the number of annual weeds decreased by 6.25 units/m2 (69.3%),
and perennial weeds by 3.62 units/m2 (73.9%), in the variant with the application of the
herbicide Ridovn Xtra 75% at a rate of 2.0 kg with the emergence of 2-3 true leaves, the number
of annual weeds decreased by 4.27 units/m2 (79.5%), and perennial weeds increased by 15.65
units/m2 (7.6%).
In the control variant with basic tillage of the soil with a two-tier plow to a depth of 28-30
cm and without the use of herbicides against weeds, the number of annual weeds increased by
21.35 units/m2 (26.1%), and the number of perennial weeds increased by 13.91 units/m2
(18.5%), and these indicators in the variant with the application of the herbicide Dafosat at a rate
of 4.0 kg/ha with sowing, the number of annual weeds decreased by 3.75 units/m2 (75.9%), and
perennial weeds by 2.14 units/m2 (82.7%), in the variant with the application of the herbicide

Ridovn Xtra 75% at a rate of 2.0 kg with the emergence of 2-3 true leaves, the number of annual
weeds decreased by 2.40 units/m2 (85.4%), but the number of perennial weeds increased by
12.86 units/m2 (5.1%).
Conclusion:
When applying the herbicide Dafosat at a rate of 4.0 kg/ha with the main
tillage of the soil with a two-tier plow to a depth of 28-30 cm and simultaneous sowing against
weeds, when applying the herbicide Ridovn Xtra 75% at a rate of 2.0 kg with the emergence of
2-3 true leaves, a sharp decrease in weeds occurs and favorable conditions are created for the
growth and development of cultivated plants.
