About this variety

Ullal-3 belongs to the "Ullal" series of cashew selections associated with work in Karnataka's coastal cashew belt (Dakshina Kannada, home to the Ullal locality the series is named for). It is one of the varieties recommended for Karnataka alongside Chintamani-1, Chintamani-2, Dhana, Bhaskara and other Ullal-series numbers (Ullal-1, Ullal-4), and is specifically documented, together with Bhaskara, as achieving the highest cumulative nut yield among tested varieties under high-density planting at 500 trees per hectare — real, direct trial evidence rather than a general adaptability claim. As with several regional selections, precise per-tree yield and kernel-grade figures independent of the Bhaskara comparison were not confirmed in this research pass.

Sowing & cultivation

  • SpacingPerforms strongly at high-density spacing (~500 trees/ha), alongside more traditional 7 x 7 m planting
  • FertilizerRoughly 500 g N, 125 g P2O5 and 125 g K2O per bearing tree per year, split around pre-flowering and post-harvest (see the crop guide for the full schedule)

Soil & climate

Soil

Suitable soil
Tolerant of poor, lateritic, gravelly or sandy coastal soil; pH 5.0–6.5

Yield & maturity

Maturity period

First bearing in 3 years (grafted)

Expected yield

High under high-density planting

Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.

Pest & disease considerations

Advantages & considerations

Why farmers may choose it

  • Direct trial evidence of top-tier cumulative nut yield under high-density planting, not just a general recommendation.
  • Part of a well-established, multi-generation Ullal series with a long history in Karnataka's coastal cashew belt.

Things to consider

  • Precise per-tree yield and kernel-grade figures independent of the Bhaskara high-density comparison were not confirmed in this pass — confirm current expected performance for your district with ICAR-DCR or Karnataka's agricultural university.

Suitable regions

States this variety is recommended for — check locally, since a state can have more than one recommended zone.

Frequently asked questions

Should I choose Ullal-3 or Bhaskara for a high-density planting?

Trials found both achieved the highest cumulative nut yield among tested varieties at 500 trees/ha, so either is a defensible choice — check current local availability and district-specific performance data with ICAR-DCR or your state agricultural university before deciding between them.
