“…Caring for each field crop based on specific soil and climatic conditions is a guarantee of high and quality yields. Under weakly saline soils, no significant change in accumulation was observed when the salt content was 0.3-0.5% by weight of dry soil, all germinated plants were evenly accumulated and healthy seedlings were formed [2,3].…”

The issue of growing field crops in saline soils and increasing their resistance to salt remains a topical issue in terms of land reclamation. In saline soils, it is important to increase the resistance of field crops to salinity on the basis of the use of advanced technologies, as well as to pay special attention to soil reclamation. The study shows that the salinity of the soils of the planned area, the lack of saline leaching and the presence of a seasonal salt accumulation process, the problem is solved from a scientific point of view, as well as its complexity. Proper timing of saline leaching is an important reclamation measure in eliminating the negative effects of salt accumulation in saline soils. When washing the soil brine in October-November, a complete leaching of the salt was achieved, resulting in a 17.6% higher biomass than the unsalted variant of the salt. The optimal irrigation rate for corn is determined by soil moisture. The number of irrigations for the biomass was set to 5 times during the growing season. At this irrigation rate, the soil moisture did not fall below 75-80% of the limited field moisture capacity (LFMC) until the oats sprouted. During the growing season, the first watering was started when the plant produced 5-6 leaves.

“…China (202-205 million tons) ranks first in the cultivation of vegetables and fruit products. Countries with developed vegetable production are India (68-75 million tons), USA (34-36 million tons), Turkey (17-21 million tons), Italy (12-15 million tons), Russia (11.5-14.2 million tons), Japan (11-13 million tons) [1,[9][10][11]. Annual production of vegetables per capita is 250-270 kilograms in China, followed by 230-250 in Italy, 150-160 in Poland, 130-145 in the USA, 120-140 in Japan, 90-100 in Ukraine, 86-94 in Russia (Figure 1) [3][4][5].…”

“…It has been found that using it along with planting and during the growing season of vegetables gives higher yield. In fact, the use of herbicides is the most effective way to keep potato and vegetable fields free from weeds, creating favorable conditions for crop development and increasing productivity [10,11]. However, repeated use of one herbicide in one field leads to the proliferation of weed species resistant to that drug.…”

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.

“…However, repeated use of one herbicide in one field leads to the proliferation of weed species resistant to that drug. Based on this, in the conditions of the Tashkent region (Uzbekistan), methods of tillage processing and the use of new herbicides are considered to be very urgent issues [8][9][10].…”

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.
