JS 12A

Stable yields in challenging conditions: why choose ZS 12 A

Serbian breeding from Institut Za Ratarstvo I Povrtarstvo is traditionally associated with predictability among agronomists. The ZS 12 A sunflower hybrid is a tool for those who want to minimize the risk of crop loss due to pathogens while maintaining high cultivation efficiency.

Field-proven protection

The main specialization of this hybrid is high resistance to diseases that often cause yield dips in regions with high humidity or crop rotation issues. ZS 12 A effectively counters a range of dangerous pathogens:

• Sclerotinia: a reliable barrier against white mold on heads and stems.
• Phomopsis and Phoma: limiting necrosis development, which is critical for maintaining stem integrity until harvest.
• Rot: increased tolerance to gray mold, allowing the hybrid to survive wet seasons with minimal losses in grain quality.

Agronomic features and application

The plant has a medium height, ranging from 150 to 170 cm. This height is optimal for most modern headers: the combine operates with minimal vegetative mass intake, reducing separation load and allowing for comfortable harvesting speeds without losses. Using ZS 12 A is justified on fields with a history of high infection pressure. It does not require complex agrotechnical management and integrates perfectly into classic intensive farming schemes. Farmers choose it as a "safety" option: the hybrid forgives certain agrotechnical mistakes, ensuring marketable grain output even in unfavorable years.
