В условиях такырных почв с признаками олуговения Сурхандарьинской
области при обработке повторной культуры подсолнечника, посеянного после озимой
пшеницы при обработке стимулятором Гумимакс перед посевом семян подсолнечника
нормой 0,75 л/т ускорилась всхожесть семян.

Abstract:
In the conditions of takyr soils with signs of meadow formation in the Surkhandarya
region, when treating a second crop of sunflower sown after winter wheat, when treated with the
Gumimax stimulator before sowing sunflower seeds at a rate of 0.75 l/t, seed germination
accelerated.

Global climate change, constant population growth around the globe and industrial
development lead to an increase in demand for agricultural products. “Currently, 28.4 million
hectares of sunflower are sown in the world, and 57.0 million tons of sunflower seeds have been
harvested.” In recent years, unfavorable weather conditions, low water levels and drought have
negatively affected agricultural production.
Однако в результате климатических изменений, вызванных неблагоприятной
погодой, дефицитом воды и засухой в последние годы, возникают проблемы при
получении высокого и качественного урожая с повторными культурными поселениями
после озимой пшеницы. To solve these problems, the development and scientific substantiation
of optimal rates and timing of the use of regrowth stimulants in the cultivation of sunflower
sown as a crop after winter wheat are considered relevant.
The oil content in modern zoned sunflower varieties is 50-52 (56)% fat by weight of the
dry matter of the seeds.
Sunflower oil is semi-drying and has high taste qualities. It is used directly for food
purposes, and is also used to produce margarine, in canning, baking, confectionery and other
areas of the food industry.
The main fatty acids in sunflower oil are linoleic and oleic acids. The content of linoleic
acid in the oil of modern sunflower varieties is 55-60% of the total fatty acids, oleic acid - 30-
35%.
Sunflower oil also contains phosphatides, vitamins A, D, E, K and other substances
beneficial to humans.

Sunflower oil of lower grades is used for the manufacture of soap, varnishes and paints,
stearin, linoleum, films, waterproof fabrics, electrical fittings, etc.
Waste from processing seeds into oil - cake formed during the press method of oil
production, and meal (or cake flour) during the extraction method - are valuable feed for farm
animals with a high protein content, which contains a large number of essential amino acids. The
share of waste accounts for 33-35% of the mass of seeds.
1 kg of meal corresponds to 1.02 feed units and contains 363 g of digestible protein. 1 kg
of cake is 1.09 feed units and contains 226 g of digestible protein.
Threshed sunflower heads also serve as animal feed. The yield of dry baskets reaches 56-
60% of the seed weight. 1 kg of flour from dried baskets corresponds to 0.8 feed units and
contains 38-43 g of protein [1].
K.M. Tadzhiev, Sh. Abdualimov [5] recommended treating sunflower seeds with the
Gumimax stimulant at a rate of 0.75 l/t to obtain a high-quality harvest from repeated sunflower
crops in the conditions of the Surkhandarya region.
Treatment of sunflower seeds with growth stimulants Gumimax has a stimulating effect
on plant growth, the effect on yield showed a positive effect in comparison with the control [2, 3,
4].
Research methods. Field experiments, laboratory analyses, phenological observations and
calculations were carried out on the basis of methodological guidelines: “Methods for
conducting field experiments”, “Methods of agrochemical, agrophysical and microbiological
research in field cotton areas”, “Methods of agrochemical analyzes of soils and plants”,
mathematical processing of the data obtained was carried out using the Microsoft Excel program
according to the method of B.A. Dospehov.
Germination of sunflower seeds begins at a temperature of 4-6 °S. An increase in
temperature accelerates the emergence of seedlings. At a temperature of 8-10°S, seedlings
appear 15-20 days after sowing, at 15-16°S - after 9-10 days, and at 20°S - after 6-8 days. The
optimal germination temperature is 12-15 °S.
The sum of active temperatures for the period from sowing to emergence of seedlings is
140-160 °S.
After seedlings emerge, the plants' heat requirements increase. In the flowering phase and
in the subsequent period, the optimal temperature for sunflower is 25-27 ° S. Temperatures
above 30 °S have a depressing effect.
The sum of active temperatures required for the ripening of early ripening varieties is
1600-1800 °S, for mid-ripening and late ripening varieties - 2000-3000 °S.
Based on the effect of using different rates of the Gumimax stimulant before sowing
sunflower seeds sown after winter wheat (Figure).
The germination rate of sunflower seeds sown after winter wheat in the control variant
was 70.9%, when using Sodium humate at a rate of 0.8 kg/t

control.

Drawing. Effect of the stimulator Gumimax on the germination of sunflower seeds sown as a
repeat crop, %
Conclusions. In the conditions of takyr soils with signs of meadow formation in the
Surkhandarya region, when treating sunflower seeds with the stimulant Gumimax at a rate of
0.75 l/t, germination increased by 14.1%, where early plant shoots were obtained in more than 1-
2 days.
