Red onion variety Scarlet is a medium-late, high-yielding type with a vegetation period from germination to maturity of 120-130 days. The bulbs have a round-oval shape, colored red-magenta with white hues of juicy scales. The weight of one bulb ranges from 80 to 115 grams. The onion has a sweet flavor with a slight spiciness, making it an excellent choice for fresh consumption, salad preparation, as well as for canning and heat processing. The variety is characterized by moderate storability and good preservation under proper storage conditions. Scarlet onion plants are long-day types and moderately cold-resistant, capable of tolerating frosts down to -3-5°C. The optimal temperature for growth and development is +20-25°C; in warm weather, the above-ground part develops intensively, while at lower temperatures, the root system develops. The onion requires intensive lighting with a daylight duration of 15-16 hours to form large bulbs. The highest water requirement occurs during seed germination, while reduced soil moisture during maturation accelerates ripening, improves storability, and prevents neck rot. For successful cultivation of the Scarlet variety, it is recommended to use fertile, moderately moist soils with neutral or slightly acidic reaction, avoiding heavy and waterlogged soils. The onion responds well to the application of mineral and organic fertilizers, promoting high yields. Seeds of this variety are suitable for cultivation both in open ground using seedlings and direct sowing. Due to its disease resistance and attractive appearance, Scarlet onion is suitable for cultivation under various climatic conditions, including garden plots and balconies.
