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 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.
A 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.
Methods of reducing drought stress and transplant shock have also been evaluated.
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.
The fungi Sclerotinia sclerotiorum and S. minor attack a wide range of vegetable crops including beans, carrots, cole crops and tomatoes. 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.
Sequential planting represents a means of insuring a consistent supply of product. Changing growing conditions and pest pressures over the season can influence the relative performance of sequential plantings.
Trials conducted a decade ago by the University of Saskatchewan demonstrated that fall planting generally results in superior yields and quality under Prairie conditions … but only if adapted varieties were planted. In 2002 and 2003, we re-examined the performance of a range of garlic varieties in fall planted trials in Saskatchewan.
