This article discusses the damage caused by pests to agricultural crops, including cotton, the importance of their control, the advantages of using modern biotechnological methods in the development of new pest-resistant varieties and foreign experience in this field, as well as preliminary research in this case was also briefly illuminated.

The global need for food and protein is increasing as an expected consequence of the growth of the human population in the world, which by 2050 will reach 9 billion people. Already, about 1 billion people in the world are chronically malnourished. Field research was carried out in 2017-2021 on the experimental field of the Research Institute of Selection, Seed Production and Agricultural Technology of Cotton Growing. In the mid-early ripe variety sample CH3(-008), the protein content was medium protein (38.16%), and the oil content was medium oil (18.66%); in variety US-25 (-622), the protein content (40.00%) was above the average level, and the oil was medium oil and amounted to 19.05%. Intervarietal variation of protein was 1.0%, oil 1.56%. The minimum total indicator of protein and oil in soybean grain was 57.44±0.40 (Arletta variety), the maximum was 60.00±32.0% (Sparta variety).

Radically enhancing of employed technologies on the growing of agricultural crops in Uzbekistan and quality of varieties has become one of the major challenges in the state priority today. Because, in the example of cotton plant as the principle crop, the republic is remaining far behind on cotton raw productivity -12th , and on cotton fiber productivity-29th than cotton producing countries. At this term, the state is a head reformer extending all scientific-technical and organizing measurements for the development of this field. The results on the study of seed stock cotton varieties’ cultivation for two years (2018, 2019) in the Burkhon farm, Navoiy division of Oqqorgon district, Tashkent region were presented in this paper. Planting quality, influences of seeds on the seed sprouting period, field germination of seed stocks, optimal seed stock expenditure, optimal seedling density, plants’ development and dynamics of yield components setting were studied in the field observations. It was identified that the used drill has planted at minimum, from 9 and maximum, up to 29 seeds per 1 m of a row. Coefficient of variation, according to the outcome of statistical analysis on the determination of difference between these two indexes has made of 29.7%. Field germination, height of plants, instability on the plants’ boll numbers and share of contamination in the variety traits of varieties were also analyzed and the necessary recommendations on new innovative ideas and technologies for improving of cotton seed production in grooving varieties and producing of seed stocks were given.
