In the experiment, 4-5-6 million seeds of Bahorikor (st), Russian Fliz, Danik, Biryuza, RFN varieties were used, and the effect on crop elements was studied. According to the sowing norms, it was proved that the elements of oilseed crop and the weight of 1000 seeds were high in the option where 4 million seeds were used, and when 5 and 6 million seeds were used, the yield elements of oilseed was higher, and the weight of 1,000 seeds were proven to be behind the option that used 4 million seeds. It has been proven that the Russian Fliz (st) variety, which gave good results on the same level as the Bahorikor (st) variety, was well adapted to the climatic conditions of Uzbekistan and prevailed over other varieties.

The oilcake contains 33-36% protein and 9-15% fat [1]. Flax is an important medicinal plant. Linseed oil is used as a dietary in patients with fatty metabolism, atherosclerosis, coronary heart disease, brain, hypertension, diabetes, cirrhosis, fatty liver failure. It is low in cholesterol and high in unsaturated fatty acids, which reduce cholesterol in foods. Mucilage collected when the seeds are heated has a softening effect on intestinal diseases [2]. In the Kutuzova S.N experiment, flax straw is used as a raw material for the production of spun yarn, in the production of thin paper and fibers. Clothes with unique sanitary-hygienic properties with bactericidal effect are sewn from linen fabrics. Linseed oil with a high iodine number dries quickly, it is best used for the production of paints, lacquer and varnishes. The possibility of processing products by biological methods attracts the world in particular [3]. Oil flax is less cultivated than fiber flax. Oily linseed oil is used in the production of varnishes, paints, linoleum, linoleum, rainproof materials, balloons. Immature seeds contain poisonous sinilic acid. Such oilcake should be given to cattle by heating them (braise) [4, 5]. Recently, flax fiber has become very common in America and has been used to make paper [6]. The unique feature of linseed oil is that it contains semi- saturated α-linoleic acid, which is part of all tissue membranes [7]. The high level of α-linoleic acid in linseed oil makes it possible to quickly dry the oil-based coatings, and is used against corrosion. At the same time, the low content of α-linoleic acid (5%) for linseed oil used in food reduces its bitter taste and oxidation level [8]. Flax is an environmentally friendly crop. Flax cleans the soil from heavy metals and radionuclides. Flaxseeds from contaminated land will not even have traces of radiation [9]. 10-13% fiber comes from the flax stem and clean paper is made. More than 300 samples of flax were collected at Research Institute of Plant Science [10]. METHODS The scientific research work was conducted in the fields of experimental scientific research and educational experimental farm of Tashkent State Agrarian University. The soil of the experimental field is a typical sierozem soil that has been irrigated since ancient times. The color of this soil is grayish-sierozem soil, and it is weakly eroded. The soil layer is grayish-yellow, with a gray- reddish, brownish tint as it moves to the lower layers. This soil is compacted according to its agrophysical properties, the thickness of the arable layer is 0-15 cm, and the thickness of the sub-soil layer is 15-27 cm. The specific gravity of the soil is 2,68-2,69 g/cm3 in the arable layer, the volume weight is around 1,34 to 1,37 g/cm3, the porosity is good from 49,07 to 50,18%. According to the mechanical composition, the arable humus layer (0-25 cm) is medium sand, the arable sub- layer (25-50 cm) and the lower layers (50-100 cm) become heavier and consist of heavy sand and light loam with fractional minerals up to 2-10%. The number of returns is 3, the number of options is 12, systematically arranged, the planted area is 0,15 ha, the number of plants is 20. The field experiment was carried out on the standard Bahorikor and Russian varieties of Fliz, Danik, Biryuza, RFN.

At the end of the growing season, the height of the stem grew by 52 cm at the end of the growing season in the control option of the Bahorikor variety of oily flax, which was planted with 4 million seeds per hectare, and 54 cm in the option with 5 million seeds per hectare and 56 cm in the option with 6 million seeds per hectare. It can be seen that in the variant with an increased sowing norm, the height of the plant grew by 4-6 cm higher than in the variants with a low sowing norm. At the end of the growing season, the height of the stem grew by 63 cm at the end of the growing season in the Fliz variety of Russia, 64 cm in the variant planted with 5 million seeds per hectare, and 66 cm in the variant planted with 6 million seeds per hectare. It can be seen that in the variant with increased sowing norm, the height of the plant grew by 2-4 cm higher than in the variants with low sowing norm. At the end of the growing season, the stem height of Beryuza variety was 72 cm in the variant planted with 4 million seeds per hectare, 74 cm in the variant planted with 5 million seeds per hectare, and 73 cm in the variant planted with 6 million seeds per hectare. It can be seen that in the variant with increased sowing norm, the height of the plant grew by 2-3 cm higher than in the variant with low sowing norm. At the end of the growing season, the height of the stem of the new Danik variety of oilseed increased to 63 cm in the variant planted with 4 million seeds per hectare, 67 cm in the variant planted with 5 million seeds per hectare, and 65 cm in the variant planted with 6 million seeds per hectare. was cm. It can be seen that in the variant with increased sowing norm, the height of the plant grew by 2-5 cm higher than in the variants with low sowing norm. At the end of the growing season, the height of the stem grew to 62 cm in the variant of the new RFN variety of linseed with 4 million seeds planted per hectare, and 66 cm in the variant with 5 million seeds planted per hectare and 6 million seeds planted per hectare. in the variant it was 65 cm. It can be seen that in the variant with increased planting rate, the height of the plant grew by 3-4 cm higher than in the variant with low planting rate. Compared to other varieties, it was found that the stem height of Fliz and Baharikor (standard) varieties was the highest. In Beryuza variety, it was proved that the stem height was lower compared to other varieties. It was studied that the total number of capsules was 30 capsules, and the weight was 2.1 g, in the option of planting 4 million capsules per hectare of the Bahorikor (standard) variety. In the variant planted with 5 million pieces per hectare, the total number of capsules was 42, and the weight was 3.4 g. It was proved that in the variant planted with 6 million seeds, the total number of capsules was 34, and the capsule weight was 2.2 g. It was found that the total number of capsules was 42, and the weight of the capsule was 3.36 g in the option of planting 4 million pieces per hectare of the Fliz variety. In the variant planted with 5 million pieces per hectare, the total number of capsules was 43, and the weight was 3.06 g. It was proved that in the variant planted with 6 million seeds, the total number of capsules was 41, and the capsule weight was 3.1 grams.

It was proved that the total number of capsules was the highest in Bahorikor (standard) and Fliz varieties of oil flax, and the lowest number of capsules was determined in the RFN variety. The average number of seeds in one plant was 1448 seeds in the 4 million seed planted variant of Bahorikor (standard) variety of oil flax, and the seed weight is 4.28 g. seeds were sown 5 million, the average number of seeds in one plant was 1251, and the seed weight was 7.3 grams. The average number of seeds in one plant was 1344 seeds in the 6 million seed sown variant, and the seed weight was 7.6 grams. The average number of seeds in one plant was 1425 in the variant of the Russian Fliz variety planted with 4 million seeds, and the seed weight was 9.12 g and it was Volume 04 Issue 06-2024 22 American Journal Of Agriculture And Horticulture Innovations (ISSN – 2771-2559) VOLUME 04 ISSUE 06 Pages: 18-22 OCLC – 1290679216 Publisher: Oscar Publishing Services Servi proved that it gave a high result compared to other varieties and norms. The weight of 1,000 seeds per plant was 6.2 grams in the variant of Baharikor (standard) variety planted with 4 million seeds, while in the variant planted with 5 million seeds per hectare, the weight of 1,000 seeds per plant was 5.82 grams. It was proved that the weight of 1000 seeds in one plant was 5.07 grams in the variant planted 6 millions of seeds. It has been proven that the weight of 1,000 seeds per plant was 6.04 grams in the Russian Fliz variety, which was planted with 4 million seeds. CONCLUSION It has been proven that the oiled flax variety has a positive effect on yield when we used it at the rate of 4 million pieces. It has been proven that the weight of 1000 seeds has also increased. The fact that the seed weight of the Bahorikor variety (control) was 4 million pieces per hectare (1448 pieces) and the Russian Fliz variety was 4 million pieces per hectare, it was proved that it was higher than the other variants.
