The Influence of Concentration of Nutrients on the Productivity of Red Beet with Inner Jet Intra-soil Irrigation of Seeds During Sowing

The study aimed to determine the effect of the concentration of nutrients on field germination and yield of red beet during jet intra-soil irrigation of seeds when sowing. The studies were conducted in the Central irrigated zone of the Rostov region on meadow chernozem soils in 2016–2018. The generally accepted methods developed by B. A. Dospekhov, V. F. Moiseichenko, V. N. Pleshakov, M. K. Kayumov, and Federal State Budget Science Institution “Federal Williams Research Centre of Forage Production and Agroecology” were applied. During the research, we used the device, technology, and irrigation standards for this method of irrigation developed by employees of the Federal State Budget Scientific Institution “Russian Research Institute of Land Reclamation Problems.” The studies showed that the most rational concentration of nutrients is 5%, where the highest rates of plant growth and development were obtained: field germination—86.6%, plant height—73.7 cm, leaf surface area—58.9 thousand square meters per hectare, yield—67,300 tons per hectare. The obtained results made it possible to establish the effect of the concentration of nutrients on the field germination and on the yield of beet during jet intra-soil irrigation of beet seeds when sowing.
