Overview  :

The Intercropping and Betel Research Station (IBRS) was established on 1993 at Narammala as a pioneer research station for intercropping of EACs under coconut cultivation. The mission of the research station is to plan and implement research and development programs for promotion of betel cultivation and for studying the feasibility of intercropping Export Agriculture Crops under Coconut. The total land extent of the research station includes 64 acre including office complex, research fields and farm. In addition to the research and development activities the station provides extension services including training and dissemination of EAC related information for the betterment of the EAC sector in Sri Lanka.
