Background
• Spring field pea may be grown economically as a green fallow crop or a grain crop in Montana
• Fallow replacement with pea can reduce nitrate leaching without decreasing profit (John et al., 2017)
![Page 11: Cool-Season Pulse & Canola Variety Trialsagresearch.montana.edu/carc/reports-pdf/PulsesCanolaFordyce.pdf · Weather Summary, precipitation (inches) ... • Seeding rate: of 8 pure](https://reader033.vdocuments.us/reader033/viewer/2022042303/5ecde3f2f0fc8b5d033e55f1/html5/thumbnails/11.jpg)
Justification
• Montana’s dry pea yields are consistently depressed relative to those of other top-producing states (NASS, 2018).
• At CARC, selection of the appropriate variety can mean a difference in yield of 611 lb/ac (10 bu/ac) in a dry growing season (2017) and 889 lb/ac (15 bu/ac) in a wet growing season (2018; n=14)

Methods
• 23 varieties (6 green and 17 yellow cotyledon types)

Cruiser Maxx (insecticide)• Grizzly Too insecticide at 1.9 oz/ac applied on
May 17th for pea leaf weevil control• Harvested: August 7th in 2018, July 25th in

Background
• Spring lentil may be grown economically as a green fallow crop or a grain crop in Montana
• Spring lentil improves soil fertility and breaks pest cycles when incorporated into wheat-fallow or wheat-only systems
![Page 24: Cool-Season Pulse & Canola Variety Trialsagresearch.montana.edu/carc/reports-pdf/PulsesCanolaFordyce.pdf · Weather Summary, precipitation (inches) ... • Seeding rate: of 8 pure](https://reader033.vdocuments.us/reader033/viewer/2022042303/5ecde3f2f0fc8b5d033e55f1/html5/thumbnails/24.jpg)
Justification
• Montana typically leads the nation in total lentil acreage, but the state’s production on a per acre basis is consistently below national averages
• At CARC, selection of the appropriate variety can mean a difference in yield of 264 lb/ac (4.4 bu/ac) in a dry growing season (2017) and 561 lb/ac (9.3 bu/ac) in a wet growing season (2018; n=5)

Background
• Technological advances in hybridization systems have led to the release of canola hybrids, which generally outperform cultivars developed by traditional breeding methods
• Many herbicide resistances exist among canola hybrids (e.g., Liberty Link, Clearfield, Roundup Ready, Sulfonylurea)

Justification
• Canola acreage in Montana has increased at a rate of 14,000 acres per year since 2010 (P < 0.01)
• Statewide average yields have increased at a rate of 22 pounds per acre per year since 1999 (P < 0.1)

Justification
• At CARC, selection of the appropriate hybrid can mean a difference in yield of 278 lb/ac (5.6 bu/ac) in a dry growing season (2017) and 183 lb/ac (3.7 bu/ac) in a wet growing season (2018; n=6)
• Frost damage may explain greater differences in 2017

Understanding Acidification and Management of Montana Soils

Background
Soil acidity in Montana can be traced to:1. Increasing N fertilizer consumption (3x since 1980s)
Microbial oxidation (i.e., nitrification) releases protons (H+) and increases soil acidity
2. Adoption of no-tillAbsence of tillage eliminates mixing with higher pH soil layers below

Methods
• 9 cultivars of: • Spring canola• Spring pea• Spring wheat • Spring barley
• Limed (5 ton/ac) and unlimed conditions• Two locations:
• Near Highwood (soil pH < 4.5)• Near Fort Benton/Geraldine (not summarized)

Results
• The potential for lime application to boost test weights is crop-dependent (P < 0.1)
• There is good potential for lime applications to boost spring pea yields, spring canola yields, and spring canola test weights, though these responses were cultivar dependent (P < 0.05)
• ROI of lime application in spring pea and spring canola systems with acidic soils may be increased with careful selection of cultivars
• A formal assessment of cultivar-specific tolerance to soil acidity is ongoing
