| Popis: | This paper considers the results of studies on substantiating the optimal combination of controllable factors of growth and development of rice that provide grain yields of 4 and 5 t/ha under overhead irrigation. We determined the reaction rates of periodically watered rice to a different combination of water and nutrition modes of the soil, which make it possible to reduce the cost of irrigation water for rice cultivation by 2.4–6.9 times compared with the conventional technology and to bring the total water consumption of this culture to being biologically sound. |
