3 DeKalb Seed and Herbicide Bayer Crop Science Seed and Herbicide Honey Bee Manufacturing New Holland Agriculture

4 Three year Research Trial 2014 was first year RCBD Split-Plot Design Four Replicates Full-scale machinery NH CR 9080 and CR9.90 Combine 35ft Varifeed, 35 ft. Rigid, 36 ft. Draper, and BPU

5 Two Sites (50-75 ac/each) Swift Current WCA Indian Head IHARF Also Humboldt in 2015 Canola Varieties InVigor L130 Standard Hybrid InVigor L140P Shatter Resistant Variety Also DeKalb BL and RR in 2015

6 Focus on combine header performance Fixed ground speed and combine loss level for all treatments

7 Four Harvest Treatments: Swath/Belt Pick-up (Control)

8 36 ft. Draper Header with rotary divider

9 35 ft. Rigid auger header with vertical knife

10 35 ft. Varifeed Header with vertical knife Knife extends forward 23 in

11 Measurements Harvested Yield Header Loss ~2000 Samples/year!! Environmental shatter loss Seed size Seed Quality Moisture Green count Oil content Dockage

12 Dry Grain Green stems and undergrowth! Low shatter losses

13 Green material = low combine productivity and plugging!

14 Drier conditions than SC, but wind event!

15

16 (2.7 bu/acre) 3 Loss (grams) (0.9 bu/acre) Right Divider crop-l130 Typical Shatter crop-l140 Resistant Left Divider Standard variety losses > than Shatter Resistant variety (across the entire header) Losses greatest at the ends and the middle of the header

17 Topography and crop conditions are a significant factor when considering straight cutting canola Indian Head Humboldt

18 Fields with variable stages of maturity not good candidates. Target uniform stands with netted crop canopy

19 Dockage Adjusted Yield (bu/ac) Good News - All tested headers are viable options! Marginal differences in yield, loss, feeding performance, ground following, etc Yield Draper Rigid Swathed Extended Knife 48 Typical Variety Canola Variety Shatter Resistant Variety

20 Header Loss (bu/ac) Header Loss Draper Header with Rotary Divider Rigid Header with Vertical Knife Divider Extended Knife with Vertical Knife Divider Extended Knife with Fixed Divider Typical Shatter Resistant Overall Canola Variety

21 Header Loss (bu/ac)

22 Rotary Vertical Knife Fixed

23 Header Loss (bu/ac) Draper Header with Rotary Divider Extendable Knife Header with Vertical Knife Divider Rigid Header with Vertical Knife Divider Extendable Knife Header with Fixed Divider Draper - Rotary dividers had a greater overall loss than the vertical knife Fixed divider - Asymmetrical loss higher on the left end (Knife drive)

24 Fixed Divider

25 Modified Divider Data coming Vertical knife better Cut height? MC?

26 Down and lodged canola difficult Rigid/Varifeed header bulldozed dirt when cutting close to ground Need good performing auto header height control Draper integrated header floatation system follows contours well cutting close to the ground.

27 Sideways auger conveyance more positive than draper Draper is more sensitive to reel position Full fingered auger grabs and compresses bushy crop under the auger Pea Auger? Extendible cutterbar allows feeding optimization based on crop density. Overall Varifeed most comfortable and forgiving header to operate in straight cut canola

28 Harvest Timing Risks due to wind Natural maturity = Patience required! Or consider desiccation Consider dockage Possibly increased Also higher moisture (storage issue??)

29 Choose flat, high, clean, fields for straight cutting canola Swath or desiccate fields with high variability in maturity Consider using shatter resistant varieties Rigid, draper, or extendable cutterbar headers are all viable header options; Varifeed shows reduced losses, and most forgiving header to operate. Fixed divider performs acceptably; Modify ends of header to provide smooth surface transitions to reduce loss Be patient depending on your region and weather or desiccate?

30 Use data with Caution 1 site, 1 yr, 1 combine, etc. Replicated Field Trial Heat and Glyphosate Reglone Naturally maturing Swath Yield, Fuel use, Productivity (bu/hr), Loss

31 Harvest aids Yield unchanged? Higher bu/hr (Heat); Swath lower losses? More fuel/hr, but faster speed (fewer hours) Caution! 1 site 1 yr 1 combine, 1 field Etc. $30/ac net negative compared to Swath Natural ripening positive $30/ac Ease of Operation
