Peanut grasses are less demanding to moisture from formation to flowering and therefore one watering is sufficient during this period. Soil moisture LFMC from flowering to ripening should not be less than 70% and the rate of irrigation should be 700-1000 m3/ha. The seasonal irrigation norm is 4000-5000 m3/ha. The number of irrigations during the growing season is 4-5. During the growing season of peanuts, the crop is kept free from weeds, weeding, loosening of row spacing and formation of soil around the bush when gynophores are formed. The purpose of the study was to select fast-ripening, high-yielding foreign peanut varieties and samples suitable for the conditions of typical gray soils of Tashkent province in Uzbekistan, optimal planting times of local varieties, feeding standards with mineral fertilizers, irrigation regime and biostimulator application technology and scientifically substantiate its impact on the level of fatness. The increase in the number and rate of irrigation of peanuts has a positive effect on the acceleration of its physiological processes and the prolongation of the growing season. When the irrigation of the “Salomat” variety was carried out in the order of 70-75-65% compared to the LFMC, the ripening period was extended by 7-10 days and amounted to 165-167 days. Irrigation of “Salomat” variety was carried out in the order of 70-75-65% compared to LFMC, with the application of mineral fertilizers in the amount of N200P150K100 kg/ha, the yield of legumes was 29.6 q/ha, in “Mumtoz” variety - 34.0 q/ha.

Agrotechnical measures and crop rotation also do not ensure complete eradication of weeds. Therefore, it is necessary to use herbicides. Mapping by type and quantity of weeds grown among agricultural crops should be carried out in all crop rotation fields and herbicides should be applied on this basis, i.e. it is important to choose one or another herbicide based on the study of the composition and amount of weeds grown in fields. In the cultivation of corn in Uzbekistan, first of all, it should be aimed at obtaining high yields from its grain. To do this, it is necessary to use all available agro-technical measures. In modern intensive farming, weed control, which is common among agricultural crops, is a key measure.
