Vegetable Research

As well as conducting annual vegetable cultivar trials, the Vegetable Program at the University of Saskatchewan researches new materials, production methods, and pest management practices aimed at improving vegetable production for prairie producers.

The Vegetable Program’s main areas of vegetable research are outlined below. Click on the link for more information and for articles detailing the individual research projects.

High Tunnel Project

High tunnelHigh tunnels are unheated, plastic-covered structures large enough to allow crops to grow to maturity, and allow sufficient space for cultivation, spraying, and harvesting to occur with the tunnels intact.

Trials conducted since 1998 have evaluated the potential for using high tunnels to enhance productivity and profitability of producing vegetable crops in Saskatchewan.

Microclimate Research

Low tunnelsA variety of materials and techniques can be employed to alter growing environments on a small scale, creating microclimates more suitable for growing certain crops in our short, cool season.

Various materials used as soil mulch, crop covers, and low tunnels have been evaluated for their effects on various vegetable crops.

Transplant Performance Research

Methods of reducing drought stress and transplant shock have also been evaluated.

Root Maggot Management

Root maggots represent a serious problem for growers of cruciferious vegetables. A series of studies were conducted to evaluate the incidence and severity of damage, chemcial, biological, and integrated management options for this pest.

Vegetable Pest and Disease Management

Repeated cropping of a site to sensitive hosts results in high population of this fungus in the soil. This study evaluated the potential to use fungicides to reduces losses to Sclerotinia spp. in direct seeded lettuce crops.

Sequental Planting

Garlic Agronomy

In 2002 and 2003, we re-examined the performance of a range of garlic varieties in fall planted trials in Saskatchewan.
