Annotation: In the article, we used a pump in an installed drip irrigation device for irrigation, i.e. taking muddy water directly from the canal and watering it without mixing. Given that until now the drip irrigation method has been used only with pure diluted water, direct drip irrigation with muddy water is being introduced into practice for the first time. During the experiments, the amount of water was saved by 40%, if during normal irrigation the water consumption was 4200 m3/ha, then with drip irrigation it was 2500 m3/ha. Mineral fertilizers are saved by 50% compared to conventional ones. In the experimental field at the beginning of the growing season, the average level of seepage water was 194-198 cm, and in the middle of the growing season, i.e. in July and August, the level of seepage water was about 185-185 cm. 187 cm. The bulk density of the soil was 1. 31 g/cm3 in the plow layer 0-30 cm, 1.39 g/cm3 in the sub-plow layer (30-50 cm) and 1.40 g/cm3 in the layer 0-100 cm. .5% of the soil mass in the soil layer of 0-50 cm, while the maximum field capacity in the soil layer of 0-100 cm was dry, we see that it amounted to 19.8% of the soil mass.
