Tomiris

Agronomic Profile and Cultivation Strategy

The 'Tomiris' maize hybrid, registered in 2025, is a mid-maturing variety specifically developed for the Polissya agro-climatic zone. With its robust plant structure and large, cone-cylindrical ears, it offers significant grain yield potential when managed with precise agronomic practices.

Sowing and Stand Density

Given the plant's height and wide leaf architecture, maintaining an optimal plant population is crucial. Overcrowding can limit light penetration to the lower canopy, which is detrimental to ear development. Farmers should aim for a density that balances the plant's need for space with the goal of maximizing the diameter of the ears.

Growth Stages and Management

• Early Development: The strong anthocyanin coloration of the first leaf sheath indicates a need for warm soil conditions at planting. Ensure soil temperatures are consistently above 10-12°C to avoid early-stage physiological stress.
• Vegetative Phase: The moderate green intensity of the leaves suggests a steady demand for nitrogen. The strongly inclined leaf position helps in moisture retention within the root zone, which is beneficial during dry spells in the Polissya region.
• Reproductive Phase: With medium timing for silk emergence and tassel flowering, irrigation management is critical during the two-week window surrounding pollination to ensure full kernel set.

The hybrid exhibits weak stem zigzagging and moderate anthocyanin coloration of aerial roots, contributing to excellent lodging resistance. The medium-length ear shank allows for efficient mechanical harvesting. To achieve the best results, focus on balanced NPK fertilization to support the rapid biomass accumulation characteristic of this variety.
