“…According to the strategic plan of Uzbekistan for 2017-2021, "3.3. consistent development of agricultural production, further strengthening of the country's food security, introduction of intensive methods and modern agro-technologies into the production sector are defined as important strategic tasks". From this point of view, it is urgent to carry out scientific research on determining the effectiveness of soil cultivation methods and the use of modern herbicides in the fight against weeds spread in potato and vegetable fields, as well as their widespread implementation [15][16][17]. Therefore, this research intends to to determine the current state of the distribution and damage caused by the types of weeds and flower parasites in the fields of potato and vegetable crops in the conditions of irrigated typical and meadow gray soils of the Tashkent region and to scientifically substantiate the measures to combat them.…”

Increasing the gross yield and quality of the potato and vegetable crops is of great importance in meeting the food needs of the population in the world. In many countries of the world, including China, weeding and herbicides are applied together with potato and vegetable planting, or during the growing season. This research intends to to determine the current state of the distribution and damage caused by the types of weeds and flower parasites in the fields of potato and vegetable crops in the conditions of irrigated typical and meadow gray soils of the Tashkent region. In this research, laboratory, field experiments in research works, phenological observations, biometric measurements were done using “Methods of conducting field experiments”, the number of weeds were studied according to A.M. Tulikov’s methodological manuals, and determination of grain suppression, statistical analysis of research results was done in accordance with A.B. Dospekhov. The results showed that among the biological groups, the group of spring weeds was dominant, accounted for 48% of the species composition. This group consisted of 14 rounds, whereas the overwintering biogroup consisted of 6 species (21%), followed by 4 species of rhizomatous weeds (14%), 3 species of taproots (11%), 1 species each of taproots and nodules (3%). According to the experiments, 45 % of the species recorded in beet fields were adapted to grow among mowed crops. This pattern was apparently related to more favorable heat, light, and nutrient regime conditions created in mowed crop fields for weed growth and development.

The increase in the world’s population means that the demand for food, including vegetable oil and protein products, is increasing day by day. Biometric measurements of the plant, laboratory analysis of soil and plant samples were done using phenological observations “Methods of conducting field experiments”, the amount of protein in soy grains was analyzed based on “Methods for determining the amount of protein in grain and its content”. The results showed that the amount of oil was 58.6% during irrigation according to the pre-irrigation soil moisture content of 65–65–60% relative to the limited field moisture capacity of the 0-50 cm soil layer during irrigation. Furthermore, it was found that when the soil moisture before irrigation was 75-75-65% according to LFMC in the calculation layer of the soil in the 0-50 cm layer in the 1-2-1 system, 1682 m3/ha water was used in soybeans, and it was 2331 m3/ha of sunflower plants.

This research delves into the repercussions of employing pilot and zeta herbicides at varying application rates to counteract the growth of common sorghum within soybean fields. The investigation is conducted within the specific environmental context of irrigated typical gray soils prevalent in the Tashkent region. The central focus of this study is to gain a comprehensive understanding of the multifaceted impacts these herbicides exert on the growth trajectory, developmental milestones, and eventual yield of soybean plants. By assessing the influence of pilot and zeta herbicides across different dosage levels, this study contributes to elucidating the potential benefits or challenges that arise from their application in this agricultural setting. Furthermore, this research endeavors to provide critical insights into the economic efficiency of employing these herbicides, thereby offering a holistic perspective on the viability of incorporating such chemical interventions within soybean cultivation practices in the Tashkent region. The implications of this study extend beyond agronomic parameters, delving into the intricate interplay between herbicide application, crop growth, and economic considerations. The findings are poised to offer valuable guidance to farmers, researchers, and policymakers who are vested in optimizing agricultural practices while considering both the ecological and economic dimensions. Ultimately, this investigation strives to enrich the body of knowledge concerning herbicidal interventions and their potential repercussions in the realm of soybean cultivation within distinct agro-ecological contexts.
