2021 Pulse Regional Variety Trials
One of the pillars of best management practices for every crop is selecting one or more varieties that are well-suited to your growing environment and spread production risk. The Alberta Pulse Growers (APG) continues to fund the pulse regional trials as the information generated empowers farmers to make informed decisions.
The tables in this publication report the yield data across the five APG zones (please refer to map). In 2021 the sites for each zone were as follows: Zone 1 – Taber, Stirling; Zone 2 – Vulcan, Oyen, Olds, Three Hills, Lacombe, Consort; Zone 3 – Andrew, Fort Saskatchewan, Westlock; Zone 4 – Fort Vermilion, Manning, Smoky River; Zone 5 – Forestburg, Stettler, Vermilion, St. Paul. Of the 70 tests planted in 2021 only 50 tests provided usable data for the following RVT tables.
Protocols for seeding, weed, insect and disease management, pre-harvest and harvest management are reviewed and standardized each year to ensure consistency of results across co-operators.
Yield of the check variety is indicated in bold, with test varieties reported as a percentage of that check variety. All sites were inspected at three points during the growing season. Data were statistically analyzed to ensure validity. Please be aware direct variety comparisons should only be made with the check.
New this year, the soybean table now presents the three zones where soybean is produced (1, 4, 5). Moving to the zone format provides better regional specific performance of the varieties. As the historical data hasn’t been provided to APG, zone information isn’t available for the previously tested soybean varieties in the lower portion of the table.
Row spacing for the dry bean trials has been restricted to the narrow row spacing only since 2019. The dry bean wide row RVT data presented in 2020 has been reposted for this year’s trials.
Along with funding it takes a team of dedicated people to establish a regional variety trial program. There are many steps including: seed set-up, planting plots, maintaining plots, harvesting, and analysis. Thanks to all those involved in making this process work — Robyne Davidson and Trina Dubitz from Lakeland College for seed set-up, the site cooperators, and a committee of dedicated seed variety contributors, plant breeders, pathologists, and researchers who review and ensure the data is presented accurately.
Additional information and specifics on management at each site including seeding date, soil fertility, in-crop herbicide and fungicide applications, etcetera can be found on the Alberta Pulse Growers website, or download the APG app.
