Altissimo F1

Hybrid onion variety Altissimo F1 is highly adaptable to various cultivation zones and yields large heads of bulbs. The plant is vigorous with uniformly round bulbs and large size. The scale color is dark brown or golden-brown, giving the onion an attractive appearance. The bulbs have a dense structure and form 1-2 tightly adhering scales, providing good protection of the skin with four tunics. The medium-early maturity cycle allows harvesting at optimal times, with fruit weight ranging from 150 to 250 grams.

Altissimo F1 exhibits high resistance to major field diseases, including basal rot and fusarium, contributing to maintaining harvest quality. The onion is frost-resistant and resilient to stress conditions, making it suitable for autumn sowing and overwintering in open ground. The plant responds well to mineral fertilizers, allowing increased yield and bulb quality.

For growing Altissimo F1, use well-lit areas with neutral and light soil. Drip irrigation helps control soil moisture and prevents waterlogging, which positively affects root system development and overall plant health. The onion is suitable for medium-term storage, allowing use over several months after harvest.
