| Abstract | Objective. A comparative assessment and comprehensive study of the morphometric parameters and yield of kale plants grown under protected conditions. Methods. Field, measurement, calculation-comparative, laboratory, analytical, and statistical methods. Results. The cultivar Chervona demonstrated the highest average plant height (60 cm), the greatest number of leaves (30 pcs.), and a well-developed leaf area (1.12 m² per plant), indicating strong vegetative growth and high photosynthetic activity. The cultivar Kucheryava had the highest average plant mass on the 90th day (250 g), which suggests effective biomass accumulation and good adaptability to cultivation conditions. Among the studied kale cultivars, Chervona showed the highest yield at all stages of development. As early as the 30th day of vegetation, its indicators significantly exceeded those of other cultivars, and this advantage persisted on the 60th and 90th days, indicating its high suitability for intensive cultivation. Biochemical analysis showed that the Scarlet cultivar had the highest nutritional value among the studied variants. In particular, its protein content was 4.0 ± 0.2%, which was statistically higher than that of Kucheryava and Chervona (p < 0.05). The phenolic compound content in Scarlet reached 50.5 ± 2.3 mg/100 g, and its antioxidant activity was 17.1 ± 0.5 μmol TE/100 g, indicating enhanced functional potential in the context of healthy nutrition. Furthermore, the vitamin C content in this cultivar was 98.7 ± 3.6 mg/100 g, which is 9.3% higher than in Kucheryava (90.3 ± 3.2 mg/100 g), confirming Scarlet's high antioxidant status. The fat content in the analyzed samples ranged from 0.9% to 1.1%, and the differences among cultivars were statistically insignificant (p > 0.05), indicating relative stability of the lipid profile. Conclusions. The kale cultivars Chervona and Kucheryava exhibited the highest yield indicators – 42.5 and 40.0 t/ha, respectively, on the 90th day of vegetation – demonstrating their high productivity potential under field conditions | ||
