Abstract
The results of many years of research on water availability and water consumption in winter wheat crops in arid conditions of the Steppe on ordinary heavy loamy chernozems are presented. It was established that climate change significantly influenced the total water discharge during the growing season, as well as the coefficient of water consumption. Over the past twenty-five years these indicators have decreased compared to the previous cycle. Due to increase in aridity, moisture availability of the soil has worsened. It is proved that the best conditions for water supply and water consumption for sowing winter wheat have shifted towards a later date. Changes are established regarding the size of water consumption by winter wheat plants during vegetation periods. Over the course of 21 years in black steam, Albatross Odessa variety provided the highest yield during sowing on September 25–6.08 t/ha, and water consumption coefficient had a minimum value of 428 m3/t.
