Onion Stalagmit

Stalagmite by Moravoseed: The Industrial Standard for Onion Processing

Stalagmite is a premium mid-season onion variety developed by the Czech experts at Moravoseed in collaboration with John Bertinat Seeds. Unlike universal varieties, this onion was engineered specifically for the processing industry and high-volume commercial storage.

The defining feature of Stalagmite is its unique round-cuboid bulb shape. While traditional round onions can be difficult to peel and process, the geometry of the Stalagmite variety is perfectly suited for automated peeling and dicing lines. This significantly reduces waste during industrial production—a key factor for manufacturers of frozen, dried, or canned onion products.

Key Performance Indicators

• Vegetation period: 100–110 days, allowing for efficient harvesting schedules.
• Average bulb weight: A consistent 160–170 grams, fitting the sweet spot for both retail and industrial sizing.
• Storage quality: Protected by a dense, light-brown skin that provides excellent shelf life and resistance to mechanical handling.

The strength of Stalagmite lies in its uniformity. Growers will find that this variety produces very consistent crop sizes, significantly reducing the labor and time required for post-harvest calibration. The bulbs hold their shape well, ensuring that the final output meets the strict quality standards of wholesale buyers.

Optimal Use Cases

Stalagmite is the ideal choice for professional farmers aiming to supply large processing contracts or premium storage markets. It is not an entry-level variety; to achieve the target weight of 170 grams, it requires a well-managed irrigation schedule and balanced nutrition. On fertile, well-managed soils, this variety rewards the grower with high, uniform yields that are hard to beat in terms of commercial viability and waste reduction.
