Corn hybrid R 21021 is a high-yielding hybrid of grain corn, intended for cultivation both as grain and for silage. This hybrid is characterized by medium plant height and optimal ear attachment, which contributes to obtaining a high yield of quality grain with good moisture shedding. Due to its characteristics, R 21021 is suitable for cultivation throughout Ukraine and demonstrates stable performance under various climatic conditions.
One of the key features of the R 21021 hybrid is its high drought resistance and strong immunity to common corn diseases such as helminthosporiosis and powdery mildew. Plants maintain functionality even under drought conditions, particularly in the latter half of the vegetation period, ensuring stable yield formation. To achieve maximum productivity, it is recommended to sow seeds at optimal times when soil temperature reaches +10-12 °C, avoiding both early and late plantings.
The hybrid responds well to increased fertilizer doses and improved agronomic cultivation conditions, further enhancing its yield. Due to its enhanced drought resistance, corn R 21021 naturally sheds moisture, simplifying harvesting and grain storage. The hybrid’s yield potential varies by region, ensuring high performance across different cultivation zones.
