RKRA 19121 SU

RKRA 19121 SU is a medium-maturing sunflower hybrid designed for cultivation under extensive and semi-intensive conditions, particularly in regions with water deficit, such as steppe and forest-steppe. The hybrid is characterized by high adaptability to dry conditions and is recommended for planting at optimal times with mandatory fertilizer application to achieve maximum yield. Plants have medium height, develop faster than average during early stages, and exhibit high oil content in seeds, making this hybrid attractive for oilseed producers.

One of the key features of RKRA 19121 SU is its high resistance to a broad spectrum of diseases and pests. The hybrid shows resistance to false powdery mildew, verticillium, fomopsis, sclerotinia, and anthracnose, and is insensitive to rust and alternaria. Additionally, it effectively resists parasitic plants such as ragweed species A-G, significantly reducing the risk of yield losses and enhancing production stability.

Yield varies depending on growing conditions and can range from 28.4 to 43.6 centners per hectare, with oil content in seeds remaining high — from 51 to 55%. The recommended planting rate is 45-60 thousand seeds per hectare, depending on soil moisture. Thanks to its characteristics and resistance, RKRA 19121 SU is a reliable choice for farmers aiming to obtain high-quality and stable sunflower yields under challenging climatic conditions.
