Abstract It has been proved in the world and our country’s agriculture that the levelling of arable lands helps the land to improve the reclamation of lands and reduce the amount of water for irrigation. According to agro-technical requirements, the height of irregularities on the surface of the fields should not exceed ± 5 cm. Experiments and research show that crop yields decreased by 1.5-1.7 times and irrigation water consumption increased by 1.7-3.4 times when the surface roughness of the fields was ± 10-13 cm. According to the research carried out by E. B. Velichko and B. B. Shumakova, in areas where the height of irregularities reached ± 3 cm, the yield increased by 1.5 times compared to ± 5 cm, and irrigation water decreased by 1.6 times. In areas with such unevenness of ± 2 cm, the yield increased by an additional 19.9 c / ha (47%), the consumption of irrigation water for the production of 1 ton of rice decreased by 36% or 1621 m3 of the economy was achieved.
