Pokkali Rice

Pokkali is a historical hereditary rice crop grown in Kerala's coastal regions, including Ezhikkara and Ernakulam, and is supported by Palliyakal Cooperative Service Bank (PCSB).
Pokkali is an old farming system that alternates one season of rice growing with another season of prawn culture.
Prawn seedlings graze on the remains of the harvested crop as they swim in from the sea and backwaters after the rice harvest.
The rice crop, which receives no additional fertiliser or manure, obtains nutrients from prawn excrement and other leftovers.
Rice and prawn cultivation are mutually beneficial.
Pokkali has an excellent gene pool that is extremely beneficial for salinity tolerance.

History

Pokkali's story begins with a massive flood that carried the seeds of this prolific grain from the Western Ghats to the low-lying salty plains.
There she flourished as a strong contender against nature's ravages, nurturing the communities that coexisted peacefully with Pokkali's farming.
Pokkali is Kerala's oldest rice variety, with a rice growing heritage dating back at least 3000 years.
It is also one of the world's oldest known crops grown using organic agricultural methods.
