Star Sids S 350

Agronomy and Cultivation of Star Seeds S 350

Registered in 2025, the Star Seeds S 350 hybrid is specifically bred for grain production in the Polissya region. This mid-maturing hybrid is characterized by significant plant height and a robust vegetative structure, requiring precise management of plant density and nutrient application.

Sowing and Field Management

The hybrid performs best when sown in soils warmed to +10...+12°C. Given its very tall stature, planting density should be carefully calculated to ensure adequate light penetration, as the leaves have a moderate waviness and medium width. The low ear placement relative to the total plant height provides excellent lodging resistance, a key factor for high-yield grain harvesting.

Growth Stages and Care

• Early Development: Strong anthocyanin coloration of the first leaf sheath indicates high vigor and adaptability to cooler spring conditions.
• Vegetative Stage: The plant features a small angle between the leaf blade and the stem, promoting efficient photosynthesis. Nitrogen management during the 6-8 leaf stage is critical for building a strong, healthy stalk.
• Flowering: Mid-season silk emergence and anthesis allow the hybrid to avoid the peak heat stress often encountered in the Polissya climate.
• Grain Filling: The ear, which features a large diameter, requires consistent moisture during the milk-dough stage. The medium-length ear shank ensures good aeration, reducing the risk of fungal infections during the final stages of maturation.

Star Seeds S 350 thrives in fertile, well-aerated soils. Due to its large biomass, it is highly responsive to balanced fertilization, particularly in the application of micronutrients during the reproductive phase.
