Why choose Tenet?

Tenet is a modern high-yielding sunflower hybrid developed by Ukrainian breeders of VNIIS. It is ideally suited for agricultural producers who aim to achieve stable yields even under challenging conditions. The early maturity period (100–105 days) makes Tenet a versatile solution for most regions of Ukraine, ensuring efficient use of the short summer season and timely harvesting.

Thanks to its high adaptability to climatic conditions and different sowing dates, this hybrid delivers consistent results in both central and southern regions of the country. A powerful root system enables efficient use of soil moisture even in dry years, while strong stems prevent lodging and reduce harvest losses.

Key advantages of the hybrid

  • High and stable yield performance. The hybrid’s yield potential reaches up to 5.0 t/ha, and field results confirm its strong leading position among early-maturing hybrids across various agro-climatic zones.
  • Disease resistance. Tenet is tolerant to Phomopsis, downy mildew, and a number of other common diseases, significantly reducing fungicide costs and minimizing yield loss risks.
  • Broomrape resistance A–G.* An important advantage for farms operating in areas with a high prevalence of the parasite.
  • Drought tolerance and adaptability. A powerful root system and flexibility to different sowing dates allow plants to efficiently use available moisture and withstand adverse conditions, including drought, temperature fluctuations, and excessive moisture.
  • Ease of cultivation. The average plant height is 155 cm, and the head attachment height ensures convenient mechanized harvesting while minimizing lodging losses.
  • High oil content. With an oil content of around 50%, the hybrid is highly efficient for industrial sunflower oil production and increases economic profitability.

Yield and recommended plant density

Ease of cultivation and plant density management. Recommended plant populations depending on moisture zone:

  • Sufficient moisture zone: 55–60 thousand plants/ha

  • Moderate moisture zone: 52–55 thousand plants/ha

  • Low moisture zone: 45–50 thousand plants/ha
