Potato Variety Trials PDF

white skinned potatoThis trial evaluates the yield and quality of standard potato varieties relative to some recently introduced types under Saskatchewan growing conditions. Trials are conducted on irrigated land in Saskatoon. Varieties are planted side-by-side in 20 m long rows with an in-row spacing of 25 cm and 1 m between rows.

russet potatoNitrogen is applied preplant and just prior to row closure (150 #/acre total). Phosphorus is band- applied at seeding (120#/acre total). Standard pest control measures are employed. The trial is planted in mid-May and harvested 90 (early) and 120 (final) days later.

Crop vigour and disease reactions are monitored throughout the season. The crop is graded and rated for yields, appearance, disease reactions and specific gravities. Scab ratings are based on results from a site with severe scab problems.

Long term average data is based on 5-10 site years of tests conducted from 1991 through 2006.

Yearly data is also available for many varieties. Click the date to view data. Recent years are also available in PDF form.
