The 'Red Giant' onion variety is a unique plant with an impressive appearance and high agronomic characteristics. This Turkestan onion is distinguished by its large spherical inflorescences of red-purple color and wide silver leaves, which give it decorative appeal. Flowering occurs from May to June, and the drooping inflorescences make it stand out among other tall varieties. Due to its beauty, 'Red Giant' is excellent for decorating borders, flowerbeds, and alpine slopes, and can also be used as a potted plant and cut flower for bouquets. The onion fruits also form large spheres that can be dried for decorative purposes. In terms of agricultural use, 'Red Giant' is an early-maturing and high-yielding variety that can be grown as an annual or biennial crop. Bulbs are large, flat-round, dense, with a golden-brown color of dry onion scales and white flesh. The variety is valued for its high yield, excellent quality, and good storage life. The onion has a sharp taste and is suitable for various types of home cooking, including canning, drying, and freezing. For successful cultivation, it is recommended to plant onions on fertile, well-processed, light soils with a neutral reaction. Onions should not be grown on the same site more often than once every six years to avoid soil exhaustion and diseases. Good predecessors include tomatoes, cauliflower, and cucumbers. Sowing seeds should be done as early as possible at a depth of about 1 cm, while planting seedlings should be done in single rows with inter-row spacing of 40 cm and plant spacing within the row of 4-6 cm. This approach ensures optimal conditions for plant growth and development, which contributes to obtaining a high and quality yield.
