About this variety
VRI-3 was developed at the Cashew Research Station, Vridhachalam, under Tamil Nadu Agricultural University, as a successor release to the station's earlier VRI-1 and VRI-2 selections. It is documented as delivering a 35–39% yield improvement over those two predecessors, a genuinely large generational jump, alongside an average yield of about 10 kg of raw nut per tree, an individual nut weight of 7.2 g, a shelling percentage of roughly 29.1%, and kernel grading at W210 — an export-standard size class. Together, these figures make VRI-3 one of the more completely documented cashew releases on this page, giving Tamil Nadu growers a clear, numbers-backed basis for comparison against older VRI selections.
Key characteristics
Sowing & cultivation
- Spacing7 x 7 m traditional (~204 trees/ha); can be planted closer in high-density systems
- 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
~10 kg/tree; nut weight 7.2 g; ~29.1% shelling, W210 kernel grade
Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.

Advantages & considerations
Why farmers may choose it
- A documented 35-39% yield improvement over the station's own earlier VRI-1 and VRI-2 selections.
- Export-standard W210 kernel grading, giving growers a clear quality benchmark for the export market.
Things to consider
- A shelling percentage of ~29.1% is respectable but not the highest among the varieties on this page — kernel recovery is one factor among several in overall returns.
- Developed and evaluated specifically for Tamil Nadu conditions — confirm suitability before planting well outside that region.
Suitable regions
Developed at the Cashew Research Station, Vridhachalam, Tamil Nadu Agricultural University.

Frequently asked questions
How much better is VRI-3 than the older VRI-1 and VRI-2?
It is documented as giving a 35-39% higher yield than those two earlier releases from the same Vridhachalam station, alongside bolder, export-grade (W210) kernels.
