The St. John’s Research and Development Centre (St. John’s RDC) was established in 1935 in St. John’s, Newfoundland and Labrador. It is one of Agriculture and Agri-Food Canada's (AAFC) network of 20 research and development centres.

The Centre is associated with one satellite location:

  • Avondale sub-station 67 km to the west where potato selections from AAFC’s Fredericton RDC are tested for resistance to potato wart, golden nematode and pale cyst nematode.

Areas of Research

The St. John’s RDC is a leader in the research, development and technology transfer of agricultural innovations that support sustainable and productive boreal-northern primary production, with a special emphasis on Newfoundland and Labrador. Agricultural practices in Newfoundland and Labrador differ from those in other agricultural areas of Canada due to the province’s cooler and shorter summers. Success has been achieved through the utilization of techniques that extend the growing season.

Research is focused on the sustainable production of horticultural (berries and vegetables) and forage crops, the development of sustainable cropping systems, biodiversity and genetic enhancement of berry crops, and innovative clean technologies and environmental practices for a boreal-northern environment.
