Harrow Research and Development Centre, Ontario

The Harrow Research and Development Centre, one of Agriculture and Agri-Food Canada's national network of 20 research centres, is located at Harrow, Ontario. The centres mission is to develop and transfer new technologies for the production and protection of greenhouse vegetables and ornamentals, and field crops, including soybeans, edible beans, corn, winter wheat and tomatoes.

This centre is a Minor Use Pesticide Program site. It is also the location of one of the largest greenhouse research complex facilities in North America and manages two field sites, one on sandy soils at Harrow and a second one on clay-loam soils at the Honourable Eugene F. Whelan Experimental Farm close to Woodslee, Ontario.

The centre has scientists and employees with expertise in plant breeding, crop physiology and management, entomology, plant pathology, weed science, and soil science.

The Harrow Research and Development Centre leads research in several areas, including:

  • Soybean and invasive species
  • Greenhouse production systems
  • Environmentally sustainable agro-ecosystems for full-season crops in great lakes watershed
  • Crop production & protection systems

The following is a publication from Harrow Research and Development Centre: Agricultural Research: Supporting Canada’s Agricultural Sector in the Development of Innovative Products and Management Practices.

Areas of Research

The Harrow Research and Development Centre focuses on new technologies for producing greenhouse crops, including vegetables and ornamentals, and field-grown processing crops, including soybeans, edible beans, corn, winter wheat, and tomatoes. Research on the quality and sustainable use of Ontario soils and reduction in greenhouse gas emissions and nutrient losses from agricultural soils are also significant activities at the centre to enhance the environmental health of farmlands.

The Centre's areas of core research are aligned with national priorities to help the sector adapt and remain competitive in domestic and global markets. Greater participation in research networks and industry-led partnerships expands the Centre's innovation capacity.

Healthy Crops in Healthy Environments

  • Conducting research on ways to improve the efficiency and marketability of crops, while maintaining the quality of the soil and the integrity of the environment (that is, reduced nutrient losses and greenhouse gas emissions)
  • Conducting regional and national studies on conservation tillage (minimal disturbances to the soil through tillage), management of water resources, managing soil nutrients, evaluating crop rotations, cover crops and conditioners to fertilize the soil including livestock manures and compost
  • Optimizing greenhouse crop management through improved production practices, energy conservation, and greenhouse environment control
  • Conducting research on beans and field vegetables with special emphasis on developing and evaluating varieties for yield, quality and disease resistance
  • Developing high-yielding soybeans and edible beans with special quality traits for food processing in order to increase both domestic consumption and marketability to Europe and Pacific Rim countries

Protecting and Preserving Greenhouse and Field Crops

  • Discovering best management practices for greenhouse and field crops to control insect and mite pests, plant diseases, weeds and invasive pests
  • Conducting research on alternative methods to control insects including physical, cultural, and biological strategies
  • Participating in Agriculture and Agri-Food Canada's Minor Use Pesticide Program for greenhouse crops and field crops in Canadian Climatic Zone 5 with the goal of finding new reduced risk pest management technologies
  • Preserving the genetic diversity of Canadian fruit crops by acquiring and maintaining wild plant material and named cultivated varieties in the Canadian Clonal Genebank

Facts, Figures and Facilities

  • Expertise in plant breeding, crop physiology and management, entomology, plant pathology, weed science, and soil science
  • 139 hectares of mainly sandy loam soil at Harrow
  • 77 hectares of Brookston clay loam soil at the Honourable Eugene F. Whelan Experimental Farm at Woodslee, Ontario
  • Heritage field plots, maintained since 1959, are of international significance for examining soil and water quality and plant dynamics on clay loam soils

  • Centre of Excellence for greenhouse and processing crops with specialized facilities
  • The "Harrow Fertigation Manager" and hydroponics
  • Located in southwest Ontario in the Great Lakes Basin which is in close proximity to Canada's largest production area for greenhouse and processing crops
  • One of seven Canadian locations collaborating on the Minor Use Pesticide Program
  • Site of the Canadian Clonal Genebank, a part of Agriculture and Agri-Food Canada's Plant Gene Resources of Canada program
