Onion Nevada

Technological Potential of the Nevada Hybrid

The "Nevada" onion from the Italian breeding company Isi Sementi S.P.A is a prime example of how modern breeding is directed toward maximum economic efficiency in the white salad onion segment. The hybrid demonstrates high adaptability to moderate latitudes while maintaining the productivity characteristic of southern regions.

Biological Features and Yield

The key advantage of this hybrid is the combination of mid-early maturity (90–100 days) with a record-breaking yield for this segment, exceeding 100 tons per hectare. Achieving such a result is ensured by the intense biomass growth of the bulb during the final vegetation stage. The rounded shape of the bulb, with an optimal weight of 80–90 grams, makes it convenient for pre-sale packaging and retail chain requirements.

Product Quality and Storage

Unlike many white salad onion varieties, "Nevada" features a dense scale structure. This technical design allows the bulb to maintain its marketability during manual harvesting, minimizing mechanical damage. An important factor is its shelf life: the hybrid can be stored for 6–7 months under proper temperature conditions, which significantly extends the sales window for the producer. The white color of the scales, combined with a mild flavor profile, makes this onion a sought-after ingredient for fresh salads.

Agronomic Recommendations

The cultivation system for "Nevada" requires a focus on irrigation during the bulb-forming period. Given its high yield potential, the hybrid demands an intensive nutrient management scheme. Utilizing seed material from Isi Sementi S.P.A, Boni Angelo, and Parma Seed guarantees high germination rates and crop uniformity, which is critical for producing a consistent commercial batch.
