As a result of the experiments, it was determined that drip irrigation of vegetables on sod-podzolic loamy soils provides an increase in yield, while maintaining soil moisture in the 0–30 cm layer throughout the growing season within 80-100% of the HB, compared to natural moisture: onions – 28.66 t/ha (179.8%), radishes (autumn sowing) – 13.7 t/ha (65 %), semi-headed lettuce - 6.6 t/ha (217.3 %), radishes (autumn sowing) – 10.8 t/ha (60.7%). Drip irrigation of vegetables ensures stable high yields and net income in the amount of: onions 44.2 t/ha (profit – 12 778.97 rubles/ha, profitability – 110.8 %), radishes (spring sowing) – 34.77 t/ha (profit – 14 818.49 rubles/ha, profitability – 74.3 %), lettuce – 8.68 t/ha (profit – 66 990.89 rubles/ha, profitability – 219.1 %), radishes (autumn sowing) – 28.59 t/ha (profit – 11 196.15 rubles/ha, profitability – 64.4 %).
