Results of testing of new domestic cultivars in the Moscow region on various backgrounds of mineral nutrition: control (without fertilizers), N120P60K180 (calculated dose) and N240P120K360 (double dose) are presented. The amount of fertilizers was calculated according to the scheme of the experiment by nutrition backgrounds and by the percentage of active substance. The soil of the experimental site belongs to the type of alluvial meadow, medium-loamy, saturated, moisture-intensive. Weather conditions were most favourable for the growth and development of table beet plants during the growing season of 2014–2017. A feature of the weather conditions of 2018–2019 was uneven precipitation, which affected the time of germination of seeds. The lack of moisture during the growing season was compensated by irrigation by sprinkling, maintaining the HB at the level of 80–85%. In 2014–2019, we studied varieties of beet of table selection of Poisk Agro Holding for commercial production: with a rounded root crop – Kreolka, Mulatka, Russkaya odnosemyannaya, Efiopka; cylindrical root crop – Slavyanka; round – Smuglyanka. The yield of root crops on the background without fertilizers varied from 36.5 (mulatto) to 47.9 t/ha (Slavyanka). Application of fertilizers in the recommended dose contributed to an increase in yield, on average, by 20.3% without reducing the marketability of products. The most responsive to mineral fertilizers in the calculated dose (N120P60K180) were varieties Mulatka (+33.1%) and Smuglyanka (+29%). The introduction of doubled doses of mineral fertilizers did not lead to a further increase in crop yield. The Creole variety showed a maximum yield of 58.6 t/ha against the background (N240P120K360) growing table beet with the use of fertilizers in calculated and doubled doses reduces the variability in the yield of varieties over the years.
Key words: beetroot, variety, mineral fertilizers, productivity, variability.
