The results of long-term scientific and industrial research are presented, which shows that the cultivation of rice during sprinkling on the lands of LLC Agrocomplex "Prikubansky" of the Krasnodar territory is possible and economically feasible. The proposed technology of irrigation of rice by sprinkling reduces the cost of irrigation water by 5-10 times compared to the traditional one, removes problems related to the environment, which depend on the continuous flooding of the cheques with a layer of water, provides high productivity and economic effect, and allows you to cultivate rice on General-purpose irrigation systems. When evaluating the varieties Volgogradskya, sonet and Novator, belonging to the early-ripe group, watered by sprinkling, the low-water-consumption variety Volgogradskya proved to be the most preferable in the experimental zone. It took 116 days to complete its life cycle with the lowest sum of average air temperatures of 2489.3 0C. It formed a yield of 5.50 t / ha of grain over the years of experiments, this is 1.50 t / ha more than the Sonet variety and 1.90 t/ha novator.
