The study examined the effect of microbiological biofertilizer based on bacteria of the genus Azotobacter on the germination of seeds in the laboratory and in the field. The results of the study showed that based on the strain Azotobacter chroococcum -XN2018, it is important not only to germinate seeds, but also to limit their contamination by disease-causing phytopathogenic microorganisms.

The article discusses the methods of growing cotton on irrigated meadow soils and obtaining a higher and higher quality crop, on irrigated meadow soils, the yield of cotton is higher than 36.1-41.3 c/ha through the use of all agrotechnical and non-traditional agrotechnical methods together. The use of cotton made it possible to obtain a high yield of 36.1 - 41.3 c/ha, as well as an increase in the resistance of cotton, cereals and other crops to pests during the foliar feeding period.

Acute respiratory viral infections are a common group of acute infectious diseases caused by viruses of similar origin. They are mainly caused by damage to the mucous membranes of the respiratory tract. The causative agents of acute respiratory diseases include adenoviruses, parainfluenza viruses, coronaviruses, rhinoviruses, and other viruses. One such viral infection was reported in December 2019 in Wuhan, Hubei Province, China, an epidemic of pneumonia of unknown origin, i.e. coronavirus disease (COVID-19). The global spread of COVID-19 and the deaths of thousands of people due to this disease led the World Health Organization to declare March 12, 2020 a pandemic. The virus was first reported in Uzbekistan on March 15, 2020. To date, countries around the world have been hit hard by the pandemic. Examples include rising poverty, loss of life, and economic backwardness.

Butterflies (Latin: Lepidóptera) are a group of insects that develop by complete metamorphosis. Originated in the early Mesozoic; the main families were formed in the early Paleogene. Fossils are mainly known from the Cretaceous period. Most butterflies' mouths consist of a highly specialized sucking hose, which spirals at the base of their heads. The curtain wings are covered with colored coins. The color of the wings, especially their different colors, is due to the fact that colorless coins absorb light at different angles, and black, yellow and other colored spots are associated with pigment. The shape and length of the mustache vary . Written wings range from 3 , 2 mm (dwarf moths) to 300 mm (dwarfs). The shape of the eggs varies and is of systematic importance. The worms have 3 pairs of thoracic legs and 5 pairs of false abdominal legs. The fungi are closed (usually inside the cocoon) and open (free) in the lower parts. Butterflies are usually divided into lower groups of lower butterflies (equal wings) and higher butterflies (different wings) . In some cases, toothed moths, which have a rodent type of oral organs, are divided into separate subgroups. The system of the butterfly family is not clearly developed, it is divided into 100 to 200 families. About 140,000 species are known. The fauna of butterflies is diverse, especially in the tropics. About 1,500 species have been identified in Uzbekistan. Large families of moths, moths, leafhoppers, and moths are especially rich in species .

Physical development is the growth and change that occurs in a person's body. The most obvious changes are changes in body shape and size. Meanwhile, motor development is the development of all forms of changes that occur progressively in a child's ability to be able to perform various movements obtained through the interaction between maturity factors and training or experience during life which can be seen through changes/movements made. In the learning process, it appears that student activities are very diverse. Starting from how they move, socialize, act, and interact with friends around them. Then from the skills of teachers in developing children's creativity so that they can produce children who have physical motor development who can adapt to the classroom environment, school, and outside of school. All these activities are positive so that they will be able to form and produce students who have great personalities, are intelligent, skilled, capable, creative, and have noble character. Suggestions for elementary school teachers are that it is necessary to provide learning that will foster students' interest in creating according to their imagination. As well as teachers can develop new media which will later be able to stimulate the physical-motor activities of students in the learning process. In the future, research is also needed to support the physical-motor development of elementary school children.

Two supports from 12-13-year-old volleyball players have been identified as the goal of studying the technique of ball transmission from above and dynamically growing it using selected moving games. Issues of the use of moving games in the initial training phase of sports equipment were taken on the example of young volleyball players. In the study, in 12-13-year-old volleyball players who were engaged in the initial training phase, special exercises and behavior games aimed at the formation of the technique of receiving and transmitting two support balls from above were selected based on the study.
