- Growing technology: Sumo (withstands high doses of tribenuron-methyl-based herbicide, but do not exceed the manufacturer’s recommended doses)
- Yield potential: up to 5.5 t/ha
- Oil content: 51–53% (up to 54% in some crops)
- Growing season: 105–107 days
- Plant height: 175–195 cm
- Resistance to broomrape: races A–G+ (tolerance to 7+ races)
- Disease resistance: downy mildew (all races)
Advantages of the Stark 7+ Sumo hybrid
Stark sunflower seeds are distinguished by their powerful initial growth energy, which ensures friendly germination even under unstable weather conditions. It is one of the most oil-rich hybrids in its segment, allowing farmers to earn more profit not only due to its yield, but also thanks to the high commercial quality of the seeds.
The main advantages of the hybrid include:
- High tolerance to broomrape, including G+ races — critically important for regions with high infestation by this parasitic plant;
- Complete resistance to all races of downy mildew, ensuring healthy vegetation;
- High stress resistance — withstands drought, heat, and temperature fluctuations;
- Sumo (Express) technology allows you to effectively combat dicotyledonous weeds at the 2–8 leaf stage of the crop;
