PECULIARITIES OF HORSERADISH CULTIVATION TECHNOLOGY UNDER THE CONDITIONS OF LLC «ORGANIK-D»

The article is devoted to the improvement of cultivation technology for horseradish, an important vegetable crop that possesses not only industrial significance but also considerable export potential and is characterized by high economic efficiency. In Ukraine, owing to its adaptability to various soil types, horseradish has become one of the traditional crops cultivated in household plots; however, in the future, it also holds strong prospects for large-scale commercial production in specialized vegetable farming enterprises. The results of a study on the complex of morphological traits and productivity of horseradish plants of the cultivar Wabi Sabi under the conditions of LLC «Organik-D» using the developed cultivation technology, which сaged a planting scheme of 70 × 30 cm, are presented. The objective of the research was to investigate the influence of the main technological elements on the productivity of horseradish plants of the cultivar Wabi Sabi under the conditions of the Right-Bank Forest-Steppe zone. The study was conducted throughout 2025 under the production conditions of LLC «Organik-D» on gray forest soils with a light loam texture and typical agrochemical characteristics for this soil type. The climatic conditions of 2025 were characterized by a substantial amount of precipitation, which during the growing season (April–November) amounted to 547.7 mm, exceeding the long-term average by 109.3 mm. The average air temperature during the growing season was 14.2 °C. It was established that the plants formed a well-developed assimilatory apparatus, with an average of 52.4 leaves per plant, a leaf length of 106.8 cm, and a root collar diameter ranging from 3.6 to 4.2 cm, which contributed to the active accumulation of assimilates in the root system. The indicators of yield structure were analyzed as follows: the length of lateral roots ranged from 43 to 62 cm with a thickness of 0.5–1.3 cm; the root collar diameter was 8.4–9.4 cm; and the mass of rhizomes per linear meter of row amounted to 0.53–0.55 kg. The formation of a well-developed aboveground biomass ensured a commercial yield of 7.57–7.86 t/ha, which exceeded the average values by 1.57–2.86 t/ha. The obtained results indicate the high efficiency of the applied cultivation technology and confirm the feasibility of its implementation in commercial practice to increase the productivity of horseradish crops.
