Onion Porbella

Technical Profile of Leek Variety 'Porbella'

The 'Porbella' hybrid, developed by Nickerson Zwaan (part of Hazera Seeds), is engineered for the professional leek market. It represents a refined approach to salad-type leek production, balancing physiological maturity with high post-harvest utility.

Growth and Maturity Cycle

With a vegetation period of 90–100 days, this hybrid fits well into mid-season production schedules. A critical technical feature of 'Porbella' is its exceptional storage capability, retaining market quality for 5–6 months under proper conditions. This extended shelf life provides producers with strategic flexibility in supply chain management.

Agrotechnical Specs

• Planting density: 250,000–300,000 plants/ha. This density is calibrated to maximize stem quality without compromising aeration.
• Harvesting method: Manual. The morphological structure of the plant is designed for efficient, damage-free manual labor.
• Target Use: Salad segment. The cultivar prioritizes tender texture and balanced flavor profiles, which are essential for fresh market requirements.

The synergy between Hazera and Nickerson Zwaan breeding programs resulted in a uniform crop canopy. In field practice, this uniformity minimizes the time window for manual harvesting, reducing labor costs. By maintaining structural integrity and low fiber accumulation in the stems, 'Porbella' remains a competitive asset for growers supplying high-end retail chains and the HoReCa sector.
