Technical Profile of the 'Pervaya Zelen' Welsh Onion

This variety is a specialized selection form of Welsh onion (Allium fistulosum), engineered specifically for high-quality scallion production. Developed by Elizaveta Romanovna Kudryavtseva, the variety balances physiological development with superior culinary properties.

Agrotechnical Specifications

• Maturity Cycle: Reaches technical maturity in up to 90 days. This duration is optimized for early-season market entry in both open-field and greenhouse conditions.
• Target Use: Salad-grade. The selection process prioritized texture tenderness and a mild flavor profile, avoiding the excessive pungency typical of wild-type Welsh onions.
• Harvesting Protocol: Hand-harvesting is mandatory. The morphological structure of the delicate leaves precludes the use of mechanized onion harvesters to ensure the integrity of the product.

The practical advantage of 'Pervaya Zelen' lies in its consistent yield of vegetative biomass. Unlike bulb-forming onions, this hybrid allocates all photosynthates to leaf development. For the agronomist, this means simplified planting density management and a predictable harvest schedule, as there is no risk associated with bulb maturation stages.

To achieve full potential, the variety requires intensive nitrogen management. Given the manual harvest requirement, it is best suited for small-to-medium enterprises where individual bunch quality is the primary market differentiator. Proper soil structure—specifically light loams—is essential for rapid growth, allowing the operator to cycle the crop effectively throughout the growing season.
