Amaranth Sem

Adaptability and Field Performance of the 'Sem' Variety

The 'Sem' amaranth variety, registered in Ukraine in 2003, remains a reliable choice for farmers focused on high-quality grain production. Developed by the State Biotechnological University, this variety demonstrates high plasticity, confirmed by its successful cultivation across all key agro-climatic zones: the Steppe, Forest-Steppe, and Polissya.

Stress Tolerance and Field Behavior

A key feature of 'Sem' is its ability to maintain productivity under unstable moisture conditions. Thanks to the biological characteristics of the crop, the variety efficiently utilizes water during critical growth phases. In the Steppe zone, it shows remarkable heat resistance: the purple coloration of the leaves and stems, characteristic of this variety, correlates with high photosynthetic activity even at elevated temperatures. The drought tolerance of 'Sem' minimizes the risk of yield loss during periods of soil and atmospheric drought, making it a robust tool for crop rotation diversification.

Agronomic Characteristics

• Maturity: Mid-season, providing an optimal balance between the growing period and nutrient accumulation in the grain.
• Morphology: An upright pink stem and a large, spreading purple panicle ensure good air circulation within the canopy, reducing the risk of fungal diseases.
• Lodging Resistance: The variety features a strong stem that maintains a vertical position even during heavy rainfall or strong winds late in the season.
• Grain Quality: Large white grains are highly suitable for efficient harvesting and processing.

Choosing 'Sem' means betting on time-tested breeding that is adapted to Ukraine's climatic challenges. The absence of pubescence on leaves and stems simplifies field maintenance and post-harvest processing, while high initial growth energy allows the crop to successfully compete with weeds, reducing the need for intensive herbicide application.
