SPANISH MEDAILON F1 is an extra-early hybrid of Spanish-type onion, developed by the Japanese company Sakata Seed. It is characterized by high yield, reaching up to 80-130 tons per hectare, achievable through various planting methods—both direct sowing and via seedlings. The maturation period is 80-90 days, allowing for an early harvest. The bulbs have an oval shape with a thin neck, weighing between 120 and 250 grams, covered by a dense, glossy bronze-brown outer skin. The internal onion scales are thick, crunchy, and juicy, with a mild and delicate flavor, making this onion in demand for both fresh market and culinary use. The hybrid plants feature compact foliage, which promotes quick and high-quality drying of the onion after lodging. The hybrid is undemanding in terms of agricultural technology, adapts well to various soil types and climatic conditions, and possesses intermediate resistance to Fusarium and pink root rot. To achieve maximum yield, balanced nutrition with a nitrogen to potassium ratio of 1:1.5 is recommended, as well as calcium fertilization in the last 20-30 days of vegetation. The hybrid responds well to mineral and foliar fertilization, especially with drip irrigation. SPANISH MEDAILON F1 is suitable for cultivation in open ground and is intended for obtaining a high-quality early crop with excellent taste qualities. Its bulbs are uniform in size and shape, have a thin neck and a small base, which facilitates their storage for 3-4 months. Due to high productivity, disease resistance, and superior taste characteristics, this hybrid is an excellent choice for farmers and gardeners focused on the fresh market and culinary use.
