ABSTRACT 

Sunflower oil ranks first among selected vegetable oils in terms of quality. Therefore, in many countries of the world, 

an increase in the level of economic efficiency is observed depending on the area of sowing and the amount of yield 

obtained from it. This scientific article develops the main elements of the technology of growing oil sunflower as a 

repeated crop to obtain high yields from early-maturing varieties. Planting sunflower as a repeated crop after wheat 

and using the correct planting schemes has led to an increase in yield. The number of seeds in one basket and their 

weight depend on the planting scheme, and when the seed planting scheme is 70x30-1 as a repeated crop, it has been 

proven that the yield elements - basket, number of seeds, weight and yield increase.

INTRODUCTION

Sunflower is a seedless plant, the seed kernel contains 

50-65% oil, 22-24% protein, vitamins (A, D, E, K) and 

phosphates. Sunflower oil is absorbed by the body up 

to 86-91%, and 100 g of oil produces 929 kcal of energy. 

Sunflower oil is used in the production of margarine, 

mayonnaise, fish and vegetable preserves, 

confectionery products, varnish, soap. 25-50 kg/ha of 

honey is obtained from sunflower.

The level of study of the problem. In experiments, 

sunflowers were planted with a row spacing of 70-90 

cm and a row spacing of 25-30 cm, which gave good 

results. When sowing using a pneumatic seeder, 6-8 kg 

of seeds were used per hectare. After germination, the 

seeds were sown with the condition of leaving 3.5-4 

seedlings per 1 m2. It was indicated that the density of 

sunflower seedlings is 35-40 thousand seeds [3], [4]. 

Sunflower varieties were sown manually on July 8, the 

planting pattern was 60x18, and the seed consumption 

was 60-65 thousand seeds per hectare. According to 

the results of the experiment, the yield was 30.2 c/ha 

for the “Yangi Zamon” variety, 30.2 c/ha for the 

“Osiyo” variety, and 25.3 c/ha for the “Buzuluk” 

variety. The highest yield was observed in the “Yangi 

Zamon” variety [7]. 

Newly developed intensive sunflower varieties can be 

planted without irrigation at the following planting 

densities: in the southern steppe - 40 thousand / ha, in 

the northern steppe - 50 thousand / ha, in the forest-

steppe - 55-60 thousand / ha. For hybrids, it is 

recommended to increase the planting density to 10-15 

thousand / ha, and an average planting density of 4-6 

kg of seeds per hectare is considered effective [1],[2]. 

METHODS  

Experiments were conducted in 2016-2018 in the typical 

gray soil conditions of the experimental field of the 

Tashkent State Agrarian University's "Center for 

Innovative Developments and Consulting in 

Agriculture". The experiment involved planting 4 

sunflower varieties: "Jahongir", "Rodnik", "Dilbar" and 

"Navruz" in 4 planting schemes: 70x20-1; 70x25-1; 

70x30-1; 70x35-1. Placement of field experiments, 

calculations and observations were determined 

according to "Methods of conducting field 

experiments" (5), stem height of sunflower varieties 

(at all stages of development), number of leaves per 

plant, basket weight, number of seeds in a basket and 

their weight, weight of 1000 seeds, leaf surface (A.A. 

Nichiporovich, 1963), influence of feeding area. 

RESULTS 

According to the results of the study, the basket 

diameter of the Jahongir control variety was 17.1 cm in 

the variant with a small feeding area of 1400 cm2, 18.2 

cm in the variant with a feeding area of 1750 cm2, 19.6 

cm in the variant with a high feeding area of 2100 cm2, 

and 20.2 cm in the variant with a large feeding area of 

2450 cm2. 

While the diameter of the baskets of the Rodnik variety 

in the same feeding areas was 18.5, 19.8, 20.9, and 22.1 

cm, the “Dilbar” variety was found to be larger than 

the “Rodnik” and “Jahongir” varieties. It was 

determined that the “Dilbar” variety had a small 

feeding area of 1400 cm2, a feeding area of 1750 cm2, a 

feeding area of 27.3 cm, a feeding area of 2100 cm2, a 

feeding area of 29.0 cm, and a feeding area of 2450 

cm2, respectively. In this variety, the diameter of the 

baskets of the control variety “Jahongir” was 10.2 cm, 

9.8 cm, 8.8 cm, and 9.3 cm larger than the variants.

It was found that Navruz variety baskets are larger in 

diameter compared to "Jahongir", "Rodnik" and 

"Dilbar" varieties studied in the experiment, and the 

baskets of this variety differed in diameter compared 

to "Dilbar" variety according to planting schemes in the 

following order: 1.7 cm, 4.2 cm, 3.8 cm and 3.5 cm. It 

was observed that the diameter of the baskets of 

"Navruz" variety compared to the control variety 

"Jahongir" was larger by 11.9 cm, 14.0 cm, 13.2 cm and 

12.8 cm. 

The weight of the baskets taken from the counted 

plants was weighed and the total weight of one basket 

was determined. It was found that the feeding area has 

a positive effect on the weight of the baskets. 

In the control variety "Jahongir" in the 70x20-1 planting 

scheme, the average weight of one basket was 67.9 

grams, after the seeds were extracted from the 

baskets, the weight of an empty basket was found to 

be 37.6 grams. In the planting scheme 70x25-1, the total 

weight was 72.3 g and the weight of an empty basket 

was 32.8 grams, in the planting scheme 70x30-1 it was 

82.6 g and the weight of an empty basket was 33.6 

grams, and in the planting scheme 70x35-1 it was 89.4 

g and the weight of an empty basket was 38.4 grams. 

It was found that the weight of the baskets increased 

according to the planting schemes of the “Rodnik” 

variety. In this case, the total weight of the basket 

according to the planting schemes compared to the 

“Jahongir” variety was 7.3, 20.6, 20.3, 16.2 grams, and 

the weight of the empty basket was 0.8 grams lighter 

in the first variant, 9.7 grams in the second variant, 5.9 

in the third variant, and 2.0 grams heavier in the fourth 

variant. 

In the experiment, the baskets of the “Dilbar” variety 

were distinguished by their large size and a large 

number of seeds in them, as well as their weight. In this 

case, the total weight of the basket according to the 

planting schemes compared to the control “Jahongir” 

variety was 18.6, 40.4, 56.2, 61.5 grams, and the weight 

of the empty basket was 3.7, 21.5, 32.6, and 30.0 grams 

heavier. Compared to the “Rodnik” variety, the total 

weight of the basket according to the planting 

schemes was 11.3, 19.8, 35.9, 45.3 grams, and the 

weight of the empty basket was 4.5, 21.5, 26.7, and 28.0 

grams heavier. 

The number of seeds in one basket and their weight 

depended on the feeding area, and an increase in the 

feeding area led to an increase in the number and 

weight of seeds. In the first variant of the “Jahongir” 

control variety, in the 70x20-1 planting scheme, there 

were an average of 620.7 seeds per plant, the weight 

of which was 30.3 grams. In the second variant, in the 

70x25-1 planting scheme, there were 650.3 seeds, the 

weight of which was 39.5 grams. In the third option, 

there were 746 seeds in the planting pattern 70x30-1, 

weighing 49.0 grams, and in the fourth option, in the 

planting pattern 70x35-1, there were 825.3 seeds, 

weighing 51.0 grams. 

The number of seeds and their weight in the "Rodnik" 

variety is higher than the indicators of the control

variety "Jahongir", in the 70x20-1 planting scheme, the 

number of seeds is 67.8 more and the weight is 8.1 

grams, and in the 70x25-1 planting scheme, it is 101.7 

seeds and the weight is 10.9 grams, in the 70x30-1 

planting scheme, it is 129.9 seeds and the weight It was 

observed that 14.4 grams, 138.5 more and 14.2 grams 

heavier in 70x35-1 planting scheme. 

In the experiment, the indicators of yield elements of 

"Dilbar" and "Navruz" varieties were close to each 

other and higher than "Jahongir" and "Rodnik" 

varieties. In the 70x20-1 sowing scheme of the "Dilbar" 

variety, one plant contained an average of 517.2 seeds, 

and its weight was 45.2 grams. In the second option, 

there were 685.4 seeds and its weight was 58.4 grams. 

The third variant contained 901.9 seeds weighing 72.6 

grams and the fourth variant contained 1053.0 seeds 

weighing 82.5 grams.

In this variety, the number of seeds and their weight 

were 83.1, 108.8, 156.1, and 238.3 more, and their 

weight was 14.9, 9.4, 23.6, and 31.5 grams, according to 

the planting schemes of the control variety "Jahongir". 

The "Rodnik" variety was 15.3, 7.1, 26.2 and 99.8 more 

and weighed 6.8, 8.0, 9.2 and 17.3 grams according to 

the planting schemes. 

The number of seeds and their weight in the variety 

"Navruz" was 106.7, 138.2, 198.5 and 285.3 more and 

the weight was heavier by 13.4, 16.4, 22.2 and 29.9 

grams, according to the planting schemes of the 

control variety "Jahongir". "Rodnik" variety was 38.9, 

36.5, 68.6 and 146.8 more and heavier by 5.3, 5.5, 7.8 

and 15.7 grams according to planting schemes. The 

variety "Dilbar" was 23.6 units more in planting 

schemes, 29.4, 42.4 and 47.0 units less in subsequent 

schemes and 1.5, 2.5, 1.4 and 1.6 grams lighter in weight. 

The weight of 1000 seeds depends on the number of 

plant stems, and an inverse correlation is observed, 

that is, the weight is heavy when planted densely, and 

light when planted sparsely. The weight of the control 

variety “Jahongir” was 69.8 grams in the first variant 

with a feeding area of 1400 cm2, 68.5 grams in the 

second variant with a feeding area of 1750 cm2, 65.7 

grams in the third variant with a feeding area of 2100 

cm2, and 62.6 grams in the fourth variant with a larger 

feeding area of 2450 cm2. It can be seen that in the 

variants with an expanded feeding area, a decrease of 

1.3, 4.1, and 7.2 grams was observed compared to the 

variant with a smaller feeding area.

The weight of 1000 seeds of the variety “Rodnik” was 

determined in the following sequence by feeding 

areas: 76.5, 74.3, 72.4, and 68.4 grams. This pattern was 

also observed in the varieties “Dilbar” and “Navruz” 

studied in the experiment. "Dilbar" grade was 87.4, 

85.2, 80.5, 78.3 grams, while "Navruz" grade was 80.8, 

78.2, 75.4, and 73.5 grams. 

CONCLUSIONS 

It was found that the weight of 1000 seeds obtained 

from the “Dilbar” variety, depending on the planting 

scheme or feeding area, was heavier than the 

“Jahongir” control variety, “Rodnik” and “Navruz” 

varieties. In this case, the weight of 1000 seeds was 

heavier than the “Jahongir” control variety in the 

following order, depending on the planting scheme or 

feeding area; 17.6, 16.7, 14.8 and 15.7 grams. In relation 

to the “Rodnik” variety, in the following order; 10.9, 

10.9, 8.1 and 9.9 grams. In relation to the “Navruz” 

variety, in the following order; 6.6, 7.0, 5.1 and 1.8 

grams.
