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.

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
