Research is an important component of the Guyana rice industry.  It is the avenue through which new technology is made available to the rice industry on a continuous basis to sustain its competitiveness in an ever changing physical, financial and social environment.

The role of the extension service at GRDB has its origins in one of the mandated functions of the organization, which is to establish facilities to conduct research relating to rice, and extend to farmers through an established system; the benefits deserved from such research.

The success of any business lies in its Marketing.  GRDB provides marketing support and services to Guyana's rice sector in four main areas; Export & Trade Facilitation, Shipping & Logistics, Promotion and Business to Business Matching.

The GRDB is the institution responsible for the Grading and certification of paddy, rice and rice by-products intended for trade in and out of Guyana. The quality Control Department carries out the statutory functions of the Board that relate to grading.
