Technical Profile of the Tomato Variety "Zvezda"

The "Zvezda" tomato, a joint development by the Poisk agro-firm and the Federal Scientific Center for Vegetable Growing, is an indeterminate crop designed for high-efficiency greenhouse environments. Given its rapid growth cycle and significant fruit weight, this variety requires precise vertical training and a rigorous pruning strategy to focus plant energy on fruit development rather than excessive vegetative mass.

Biological Specifications and Performance

With a maturity period of up to 90 days, Zvezda is positioned as an early-ripening, high-intensity variety. The technical parameters of the harvest include:

• Fruit Weight: Exceeding 200 grams, ensuring high commercial yields per square meter.
• Structure: Uniform rounded shape with a resilient skin profile, minimizing cracking and post-harvest damage.
• Coloration: Genetic versatility allowing for both red and yellow phenotypes, offering flexibility for market segmentation.

To maximize the productivity of this indeterminate type, the nutritional management must be adjusted to the rapid fruit-fill phase. A standard intensive fertilization program—focusing on phosphorus and potassium—is essential once the third truss begins to form. Due to the accelerated timeline of maturity, consistent soil moisture through drip irrigation is critical to prevent water-related stress. This variety demonstrates optimal performance when managed within a 2.5–3 plants per square meter density, allowing for optimal light penetration and airflow through the canopy.
