The article presents research data on the content of productive moisture in leached heavy loam chernozem bygranulometric composition, in grain-steam crop rotation by the predecessor of peas in spring barley crops with various tillagesystems. The research was carried out in the Kemerovo Research Institute of Agriculture, branch of the Siberian FederalScientific Center for Agrobiotechnologies of the Russian Academy of Sciences. In spring barley crops, according to the phasesof its development (tillering, ear formation), the combined deep and no-till systems had an advantage in terms of the content ofproductive moisture in the soil layers 0-20 and 0-50 cm in relation to the control crops (dump deep), both when sowing it in itspure form and when sowing it together with clover. The highest content of productive moisture in the tillering phase of springbarley was observed in binary crops in a soil layer of 0-50 cm with no-till system - 74.97 mm (control - 62.4 mm). The studyestablishes a close relationship between the content of productive moisture in the meter layer of soil and its presence in the soillayer 0-20 cm, r = 0.7379* and the layer 0-50 cm, r = 0.9377*. In the 0-100 cm soil layer, the content of productive moistureexceeded the control in pure spring barley crops in the tillering phase by 13.3% with the no-till system, by 14.5% with acombined minimum treatment, and by 15.4%, with a combined deep treatment, in binary crops — by 11.3%, 6.1% and 9.0%,respectively.The study determines the correlation between the hydrothermal regime and the content of productive moisture in thetillering phase in both pure and binary crops with all tillage systems, depending on the soil layer, r = 0.8389- 0.9998*.
