RH 21034 is a high-yielding corn hybrid known as Evrostar, developed by breeders of the company LIDEA (Euralis/Caussade). This mid-season hybrid with a FAO index of 210 has a vegetative period ranging from 100 to 110 days, enabling effective use in various climatic conditions. Plants reach medium height, have a strong stalk and a well-developed root system with good branching, ensuring stability and consistent yield. Cylindrical ears contain 16 rows of kernels, each with approximately 26 cream-colored kernels. The thousand-kernel weight is 301 grams, indicating high-quality seed material. RH 21034 exhibits high plasticity and adaptability to different growing regions, maintaining stable yield performance for both grain and silage use. It possesses high tolerance to a broad spectrum of adverse factors, including major corn diseases such as Fusarium, downy mildew, and bacterial blight. Additionally, the hybrid is relatively insensitive to weed and pest pressure, reducing the need for intensive plant protection and promoting eco-friendly production. Special attention has been given to RH 21034’s resilience to adverse climatic conditions: it successfully withstands drought, high solar radiation, and late spring frosts. Recommended planting rates vary depending on soil moisture levels: for adequately moist zones, the optimal density is 95,000 plants per hectare, while for less moist zones, it is 80,000 plants per hectare. These parameters allow for the optimal utilization of the hybrid’s potential and ensure high productivity under various agronomic conditions.
