About this variety

Vengurla-7 was recommended for release in November 1997 at the XIII Biennial Workshop of the All India Coordinated Research Project on Cashew, developed at the Regional Fruit Research Station, Vengurla (Konkan Krishi Vidyapeeth, Maharashtra) from the specific cross Vengurla-3 x M10/4 (also referenced as VRI-1 in some records). It is among the better-documented cashew releases in terms of hard numbers: an average yield around 18.5 kg of raw nut per tree, bold nuts weighing about 10 g each, a kernel grade of W180 (a recognised export size class) and a shelling percentage of roughly 30.5%. It is also noted for a very high percentage of perfect (bisexual, self-fertile-flower-bearing) flowers on its panicles, a trait that supports more consistent fruit set than varieties with a higher share of purely male flowers.

Pest & disease considerations

Advantages & considerations

Why farmers may choose it

  • Well-documented bold nuts (10 g) at an export-recognised W180 kernel grade — a genuine quality edge in export markets.
  • A very high percentage of perfect (bisexual) flowers supports more consistent fruit set than many other selections.

Things to consider

  • A shelling percentage of ~30.5% is moderate, not exceptional, compared with some other releases — kernel recovery matters as much as raw nut yield for overall returns.
  • Detailed disease-resistance data specific to Vengurla-7 was not confirmed in this pass — apply the crop's standard tea mosquito bug and dieback management regardless.

Suitable regions

Released 1997 at the Regional Fruit Research Station, Vengurla (Konkan Krishi Vidyapeeth, Maharashtra); grown across Maharashtra, Goa and Karnataka.

Frequently asked questions

What does the W180 kernel grade mean for Vengurla-7?

W180 is a recognised export kernel-size grade (roughly 180 whole kernels per pound) — a bolder, more valuable size class than smaller grades, which is part of why Vengurla-7's nuts fetch a good export price.
