The Sherman F1 onion is an early-maturing hybrid of semi-pointed bulb onion, developed by the Dutch breeding company Bejo Zaden. The maturation period ranges from 80 to 110 days after emergence, allowing for early harvest. The plant has a well-developed root system and medium-sized foliage, which promotes rapid drying of bulbs both in the field and during storage. The onion forms round or dome-shaped bulbs with uniform size, averaging 100-120 grams, with individual bulbs reaching 130-150 grams.
The bulbs have a dense, firm bronze-colored outer scale with a greenish tint, tightly adhering to the flesh and forming several layers. The inner scales are white, succulent, and meaty. The taste of Sherman F1 onion is semi-sharp with moderate sweetness and practically no bitterness, making it versatile for culinary use. It is suitable for salads, first and second courses, marinades, and preservation.
The hybrid exhibits high resistance to fusarium, pink rot, and bolting, ensuring stable yield and storage. Under proper cultivation conditions and drip irrigation, yields can reach 40-50 tons per hectare, while under standard care, approximately 30 tons. The onion adapts well to various soil types and climatic conditions, capable of growing even without irrigation or fertilization. Recommended planting density is 10 cm between plants and 20 cm between rows, with spring planting depth of 3-5 cm and winter planting depth of 6-10 cm. Due to its qualities and characteristics, Sherman F1 is an excellent choice for commercial cultivation and long-term storage up to 3-4 months without loss of marketability.
