About this variety
Eureka is an internationally established walnut cultivar cited in regional variety literature as long grown in Himachal Pradesh's hill-district orchards alongside Franquette and other proven imported selections — part of the mix of international cultivars Himachal Pradesh growers have relied on for decades alongside more recently released SKUAST-Kashmir and ICAR-CITH selections. As with several other long-established international walnut cultivars grown in India, detailed India-specific agronomic data (precise yield figures, disease-resistance ratings, and chilling requirement under local conditions) is thinner than for the newer, more thoroughly evaluated Indian institutional releases. It remains a genuine, currently planted option in established Himachal Pradesh orchards, but growers should confirm current nursery availability and expected local performance with their state horticulture department or KVK rather than relying solely on general international reputation.
Key characteristics
Sowing & cultivation
- Spacing8 × 8 m under traditional planting; confirm current local spacing practice with your state horticulture department
- FertilizerA balanced NPK dose while young, moving to a higher, pre-spring-growth-and-post-harvest-split dose once bearing, following general temperate nut-tree practice in the absence of an India-specific schedule (see the crop guide)
Soil & climate
Soil
- Suitable soil
- Deep, well-drained loam; pH roughly 6.0–7.5; genuinely intolerant of waterlogged or heavy ground
Yield & maturity

Advantages & considerations
Why farmers may choose it
- A long, established planting history specifically in Himachal Pradesh's hill-district orchards.
- Grown alongside Franquette and other proven cultivars, giving growers an established local track record to draw on informally.
Things to consider
- Detailed India-specific yield, chilling-requirement and disease-resistance figures are thinner for Eureka than for the newer SKUAST-Kashmir and ICAR-CITH releases — treat general international reputation as a starting point, not a guarantee.
- Confirm current nursery availability and genuine trueness-to-type with a reputable Himachal Pradesh nursery before planting at scale.

Frequently asked questions
Is Eureka a good choice for a new walnut planting today?
It remains a genuinely planted, established option in Himachal Pradesh's existing orchards, but detailed India-specific performance data is thinner for it than for the newer institutional releases like Hamdan, Sulaiman or Parbat. For a new planting, it is worth comparing Eureka's established local track record against a named institutional release's more thoroughly documented figures, and confirming current recommendations with your state horticulture department.
