The article presents a study of water consumption of rice crops during periodic watering in various interphase periods of the growing season. The experiments were carried out on a plot of 21.2 hectares in the rice-growing enterprise RBF "Krasnoarmeysky", geographically located on the Kuban rice irrigation system. The object of the study was an intensive variety of Rapan rice of Russian selection. The subject of the study was the water regime during the growing season of rice. It was found that the transition to intermittent irrigation during the growing season of rice "germination-tillering", "tying-flowering" and "ripening" allowed to reduce the irrigation rate by 2122.83, 949.66 and 279.32 m3/ha, or by 11.4, 5.1, 1.5%, respectively, compared to traditional methods of rice irrigation. The results of harvesting rice grains showed that the average yield according to the experiment was 75.7 c/ha, which is more than in the control by 1.2 c/ha. Additional profit from the increase in yield on the experimental variants ranged from 1,440 rubles/ha to 2,880 rubles/ha, net profit - from 480 rubles / ha to 960 rubles/ha.
