Продуктивность суходольного риса при капельном орошении

Under the optimal combination of soil water and nutritious regimes, productivity of plants increases, as they are able to use the reserves of moisture and nutrients in accordance with the biological needs. The interaction between these factors favorably affected the activity of growth and development of plants. Field experiment was carried out for 3 years (2013-2015.) on the experimental field of All-Russian Scientific Research Institute of Irrigated Agriculture (VNIIOZ, Volgograd) with cultivating Volgograd rice variety. The interaction effects of the combination of water regimes and doses of mineral fertilizers (NPK) on rice yield, yield components, formation of the root system of rice under drip irrigation system were studied in three replications.
