INTRODUCTION 

Every day the role and importance of the agricultural 

sector in ensuring the food security of the world's 

population is increasing. In particular, an urgent task is 

to use the resources and opportunities available in our 

country to provide the population with agricultural 

products, further increase productivity and introduce 

scientific achievements and modern approaches to the 

sphere. 

Sunflower is one of the main oilseeds in the world. 

Sunflower oil plays an important role in meeting the 

needs of the population in vegetable oil. Sunflower 

seeds contain up to 55% oil, of which vegetable oil is 

mainly used for food. Margarine is made from 

sunflower oil. The low-quality part of sunflower oil is 

used for technical purposes. Cake obtained by 

processing seeds into oil is very nutritious, contains

about 20-35% protein and is a good feed for dairy cows. 

Oily sunflower varieties do not branch. 

Sunflower silage is well eaten by all kinds of animals. 

Silage is much more nutritious, contains easily 

digestible protein, carbohydrates, mineral salts and 

vitamins. In 100 kg of silage there are 16.2 feed units 

and 0.7 kg of digestible protein. Varieties intended for 

animal feed branch well. When sowing forage, it is 

recommended to sow in combination with corn. 

As part of the development strategy of the new 

Uzbekistan for 2022-2026 and the "Year of Human 

Dignity and Active Neighborhood", tasks were set to 

develop a program for 2022 and to increase the range 

of processed meat, milk, fruits, vegetables, oils and 

fats for industrial use from 898 up to 1100 items. 

The innovative technology of sunflower cultivation is 

based on the integrated use of the biological potential 

of the productivity of modern hybrids and varieties in 

different agro-ecological growing conditions, 

optimization of water and nutrient regimes in soils, the 

use of an integrated plant protection system against 

weeds, diseases and pests, modern complexes of 

machines for cultivation and harvesting. 

The cultivation of oilseeds in the country, along with 

the creation of opportunities for the rational use of 

land, opens up a wide path to solving the problem of 

meeting the needs of the population in food, i.e. fat 

and oil products. 

In the conditions of irrigated lands of the Republic of 

Uzbekistan, it is effective to sow sunflower as a feed in 

areas freed from grain crops, and the best time for 

sowing sunflower is from June 15 to July 15. 

Purpose of the study: The study of sunflower varieties 

and hybrids imported from Russia in the framework of 

bilateral cooperation at the Research Institute of Grain 

and Leguminous Crops is the purpose of this study. 

Results of the study: Twelve varieties and hybrids of 

sunflower were brought from the Russian Federation 

to the Research Institute of Grain and Leguminous 

Crops, planted and tested in 2021 on a field freed from 

grain crops to study adaptability to irrigated soil and 

climatic conditions of Uzbekistan. 

Long-term experience shows that sunflower in a crop 

rotation should return to its former field no earlier than 

after 8-10 years. Violation of the return principle can 

lead to mass damage by broomrape, downy mildew, 

white, gray, ashy rot, Fusarium, Phomopsis and other 

pathogens, and ultimately to a decrease in yield. 

Field experiments were carried out in conditions of 

irrigated meadow-serozem soils. In the experiment, 

the seeds of sunflower varieties and hybrids were 

sown to a depth of 5-6 cm with an SCh-4 pneumatic 

seeder according to the scheme 60 cm x 30 cm x 1 as a 

repeatedcarrying out technological measures that 

provide optimal conditions for the formation of a high 

yield and its quality. 

Sunflower has a high ecological plasticity. It develops a 

powerful root system, penetrating to a depth of 150-

300 cm, which makes it possible to use the moisture of 

deep soil layers that are inaccessible to many other 

field crops. 

Since sunflower develops a powerful root system, it 

should not be placed directly after crops with a deep-

penetrating root system - sugar beet, alfalfa, Sudanese 

grass. These precursors strongly desiccate the soil to a 

great depth, which leads to a moisture deficit during 

the critical flowering-seed-filling period for sunflowers. 

In irrigated soils, sunflower after these crops can be 

sown in 1-2 years. Sunflower should not be placed

earlier than 3-4 years after soybeans, peas, rapeseed, 

beans, as these crops have a number of common 

diseases. The best predecessors of sunflower are 

winter crops, a good one is corn for silage. 

Fertilizers are one of the effective means of increasing 

the yield of sunflower. The effectiveness of their 

application depends on the biological characteristics of 

varieties and hybrids, the provision of soils with 

available forms of nutrients, the timing and methods of 

application. 

The main fertilizer provides the need for sunflower 

plants in nutrients throughout the growing season. 

Organic and mineral fertilizers are used as the main 

ones. Of the organic manure, the effectiveness of 

which depends on the conditions of moisture and the 

temperature regime of the soil is of the greatest 

importance. The optimal rate of manure is 20 t/ha 

applied in autumn. 

In the ongoing experiments, the annual norm of 

phosphorus and potassium from mineral fertilizers for 

sunflower is given at the rate of 90 kg of pure 

phosphorus and 60 kg of potassium per hectare during 

the period of land preparation before sowing. 

During the period of crop care, the first top dressing 

was carried out with nitrogen fertilizers in the phase of 

4-6 leaves of the plant to a depth of 10-12 cm between 

rows of 90 kg/ha of urea in its pure form. During the 

period of formation of 10-12 leaves in the plant, the 

second top dressing was carried out with ammonium 

nitrate in the amount of 70 kg/ha with pure fertilizer by 

the cultivator to a depth of 14-16 cm between the rows. 

The crops were irrigated after each feeding. Also, 

during flowering and grain filling, regular watering was 

carried out, depending on soil moisture and the state 

of the crop. 

During the growing season of sunflower, with the help 

of a cultivator, row-spacings were treated 3 times, 

chemical treatments were carried out against diseases 

and pests. 

According to Table 1, the height of the Umnik and 

Buzuluk varieties is 185 and 188 cm, respectively, and in 

the hybrids Natalie, Mercury, Fakel, Elion, Epsilon, 

Nord, Revansh, Arneb and Typhoon, the height was 

185, 180, 186, 193, 190, 170, 179, 175, 175 and 180 cm 

respectively. In general, it was noted that all varieties 

and hybrids in the test completely went through the 

phases of growth and development. 

According to the results of field trials, varieties Umnik 

and Buzuluk fully ripened in 90 and 95 days, 

respectively, and hybrids Natali, Mercury, Fakel, Elion, 

Ersilon, Nord, Revansh, Typhoon, Arneb and Aris in 98, 

93, 90, 99, 100, 88 , 85, 100, 92 and 95 days respectively. 

According to the results of the experiments, the 

highest yield was obtained from 2 varieties and 4 

hybrids of sunflower grown as a re-crop in the fields 

freed from grain crops. The yield of sunflower varieties 

and hybrids was as follows: varieties Umnik 28.9 c/ha, 

Buzuluk 27.8 c/ha and hybrids Elion 27.5 c/ha, Arneb 27.1 

c/ha, Aris 26.7 c/ha, Typhoon 26.5 q/ha.

This means that if the average yield of cereals planted 

as the main crop per hectare is 6.0-7.0 tons per hectare, 

then from the variety and hybrids of sunflower planted 

on this area as a secondary crop, you can get a yield of 

2.5- 3.0 t/ha. As a result, 8.5-10.0 t / ha of crop is 

obtained from 1 ha due to the double harvest from one 

area. 

Due to re-sowing, the amount of agricultural products 

grown from 1 ha will increase by 1.5 times. This is 

certainly important for ensuring food security. 

CONCLUSION 

In conclusion, we can say that when growing sunflower 

varieties Umnik, Buzuluk and hybrids Elion, Arneb, Aris, 

Typhoon on plots freed from grain crops in the soil and 

climatic conditions of Uzbekistan, it is possible to 

productivity is about 2,5-2,9 c/ha
