Rootstock KA 92

A reliable foundation for an intensive orchard

When selecting rootstock for pears, the priority is not just growth vigor, but the tree's ability to survive in harsh climatic conditions. "KA 92" is the choice for those who do not want to gamble with frosts. This semi-dwarfing rootstock, developed by experts at the Nikita Botanical Gardens, acts as a true "insurance policy" for your orchard.

Performance and Graft Compatibility

In practice, "KA 92" is highly predictable. The primary advantage for an operator is its high graft compatibility with the majority of pear varieties. This is a critical factor that directly influences survival rates during orchard establishment. You won't have to waste resources on re-grafting or culling sub-standard seedlings: if the grafting is performed according to technical standards, the tree will develop uniformly, without constrictions or overgrowths in the trunk zone.

Winter Hardiness as a Key Asset

The cold resistance rating of up to -35°C moves this rootstock from the experimental category to a proven solution for regions with severe winters. In operational terms, this means zero risk of root system loss during sudden temperature drops. The trees do not "wake up" prematurely and maintain stability even during extreme soil freezing.

Operational Benefits

• Medium growth vigor: ensures convenience during pruning and harvesting operations — no need for high-altitude machinery or complex ladder systems.
• Stability: uniform crown development allows for precise planning of planting density without the risk of overcrowding.
• Resource efficiency: adaptability to soil conditions and resilience to climatic stress reduce overall maintenance and crop protection costs.

Using "KA 92" is a rational approach to the orchard business, prioritizing long-term plantation life and predictable yields.
