  • Description: Studies have found that the sub-surface method of winter wheat irrigation halves the number of irrigations and reduces the crop water consumption by 970-1015 m3, inter-row treatment procedures, and the consumption of fuels and lubricants. The productivity of winter wheat grain in comparison with the control (without sub-surface irrigation) is increased by 0.9 t/ha, environmental pollution from agrochemicals is prevented. The sub-surface irrigation method in conditions of meadow soils with a groundwater level of 1-3 m and mineralization of 1-3 g/l experimented in this paper and the influence of this method on the development dynamics of winter wheat (Polovchanka) on obtaining high yields was also tested. The number of irrigations increased to 6-7 times instead of 3-4. Therefore, on such lands, we recommend while designing the drainage system, the designers should plan the depth of the drains no more than 1.5 meters. Sub-surface irrigation is a temporary closure of closed drainage during the growing season of winter wheat, leading to an increase in groundwater level (80-130 cm), thereby leading to an increase in the moisture reserve in the soil.
