The results of water consumption of vegetable crops (onions, radishes, lettuce) on sod-podzolic slightly loamy soils under drip irrigation conditions (field experiments  2021‒2023 in the north-eastern zone of Belarus) are presented. To determine the water consumption of these crops, the water balance method and the method of  maximum daily air temperatures were used. As a result of field experiments, it was established that the water consumption of vegetables on sod-podzolic loamy soils  depends on the heat supply of the growing season and the norms of drip irrigation, due to the uneven precipitation and heat distribution within the growing season. It  requires additional moistening of vegetables, both in dry and in years with moderately wet precipitation.
