WHITE, LONG / DLOUHÝ BÍLÝ

Professional Grade: Focus on Storage and Yield

The «White, Long» (Bílý, Dlouhý) parsnip variety from the Czech breeder Semo is a staple for growers aiming for high-quality produce for the fresh market during the winter season. With a maturity cycle of 210–220 days, it is a deliberate choice for agricultural operations focused on late-harvest inventory.

Field Management and Application

• Soil Requirements: Given the morphology of the roots, deep and light sandy loam soils are non-negotiable for success. To prevent deformation, growers must ensure deep plowing and soil preparation, as the variety relies on unrestricted root penetration to develop its signature straight, marketable shape.
• Commercial Strategy: This variety is bred for durability. It performs exceptionally well when mechanical harvesting is involved, provided the harvesting equipment is calibrated to the depth of the roots. Its dense texture ensures minimal bruising during sorting and washing.
• Post-Harvest Handling: Designed specifically for the long haul, these parsnips are ideal for controlled-atmosphere storage. They maintain their structural integrity and flavor profile long after the harvest, making them a reliable asset for late-winter and spring supply chains.

For commercial farms, "White, Long" offers a predictable production cycle. Weed control is essential during the early stages of establishment, as the crop has a slow emergence phase. Once the canopy closes, the crop requires minimal intervention, allowing producers to focus on irrigation management to maintain root turgidity through the heat of the summer.
