RHA SU is an ultra-early sunflower variety with a short growing period of 74-78 days, which allows for efficient use in obtaining a second crop per year after winter crops. The variety is characterized by high adaptability and stable productivity under various climatic conditions, including steppes, forest-steppe, and forested areas. Thanks to its high drought resistance and lodging resistance, RHA SU is suitable for cultivation in all climatic zones, ensuring a reliable harvest even under unfavorable weather conditions.
RHA SU sunflower seeds have a high oil content, making this variety attractive to the oil industry. The cultivation technology involves the use of modern herbicide systems such as Sulfo and Express SX, which provide effective protection against weeds and diseases. The variety demonstrates high resistance to sunflower stem rust (cercospora), verticillium wilt (races AG), as well as to new races of powdery mildew, Phoma brown spot, and white rot of the head, which contributes to maintaining plant health and increasing yield.
A feature of RHA SU is innovative seed treatment, which promotes rapid growth at the beginning of the growing season and maximum realization of yield potential. The recommended sowing rate varies depending on soil moisture, which allows optimizing the planting for specific conditions. High tolerance to leaf and head diseases, as well as stable yield indicators, make this variety a reliable choice for farmers seeking to obtain a quality and profitable sunflower crop.
