Determining the Optimum Seeding Window for Soybeans in Manitoba (2017-2019)

Crop Types: Soybean

Centre(s): PESAI

The objective of this study is to determine the optimum seeding window for soybeans across Manitoba growing regions. Traditional recommendations are to plant soybeans when soil temperature has warmed to at least 10°C, which is typically May 15-25 in Manitoba (Manitoba Agriculture). However, farmers have started to seed soybeans earlier and recent work by Dr. Yvonne Lawley and Cassandra Tkachuk (2017) supports this trend. They evaluated seeding dates across a range of soil temperatures from 6 to 14°C in 2014 and 2015; the earliest seeding dates maximized yield regardless of soil temperature and it was concluded that calendar date is a superior indicator. To update seeding date recommendations across a wider range of environments and using defined calendar dates, this study was initiated at Arborg, Carman, Dauphin and Melita in 2017 and will continue through 2019.

The objective of this study is to determine the optimum seeding window for soybeans across Manitoba growing regions. Traditional recommendations are to plant soybeans when soil temperature has warmed to at least 10°C, which is typically May 15-25 in Manitoba (Manitoba Agriculture and Resource Development). However, farmers have started to seed soybeans earlier and recent work by Dr. Yvonne Lawley and Cassandra Tkachuk (2017) supports this trend. They evaluated seeding dates across a range of soil temperatures from 6 to 14°C in 2014 and 2015; the earliest seeding dates maximized yield regardless of soil temperature and it was concluded that calendar date is a superior indicator. To update seeding date recommendations across a wider range of environments and using defined calendar dates, this study was initiated at Arborg, Carman, Dauphin and Melita in 2017 and 2019 was the last year of testing.

Evaluating Organic Acids in Canola-Soybean crop rotation (2019-2021)

Crop Types: Canola, Soybean

Centre(s): PESAI

Evaluating Tile Drainage/Water Management Effects on Wheat, Canola and Soybeans productivity in Heavy Clay soils (2019-2021)

Crop Types: Canola, Soybean, Wheat

Centre(s): PESAI

The main objective of this research is to assess the impact of tile drainage (15’, 30’ and 45’ wide) and water table management on yield and quality of canola, soybean, and wheat. The data collected from this research will be used to develop computer models that can simulate tile drainage operation under different rainfall patterns, thus extending the usefulness of this research beyond the three-year period.

Evaluation of different Inoculants on the Soybean Productivity (2016)

Crop Types: Soybean

Centre(s): PESAI

Soybeans grown in Manitoba are usually inoculated with Bradyrhizobium japonicum to ensure adequate bacteria populations are present to maximize nodulation and nitrogen fixation. Soybean farmers in Manitoba have a variety of inoculant choices available. The effectiveness of different inoculant types, however, is not fully understood in the various soybean-growing regions in Manitoba. The current study is planned to determine if there is any additional yield benefit to: 1. Using in-furrow granular inoculant (instead of seed-applied liquid) 2. Double inoculating (seed-applied liquid + granular in-furrow) (compared to seed-applied liquid only) 3. Increasing the rate of inoculant (from 1x to 2x) 4. Using "enhanced" inoculant products
