Canola Desiccation Brian Jenks, Jordan Hoefing, and Gary Willoughby North Central Research Extension Center Minot, ND
Summary of 2005-07 results • Desiccant comparison: • Desiccating with Paraquator Diquatproduced yield and quality results similar to swathing….when applied at proper timing. • Yield, test weight, oil content, seed loss were similar. • However, green count tended to increase with early applications and lodged canola. • Swathing tended to provide lower harvest moisture, but desiccating also produced acceptable harvest moisture.
Summary of 2005-07 results • Timing comparison: • Applying the desiccant before seeds in middle pods had turned color resulted in higher green count, lower yield, and lower test weight. • Swathing too early caused similar results.
Summary of 2005-07 results • Harvest comparison: • Minimal seed lost due to shattering at 7 or 14 DAT. • Generally lost <50 lb/A • Desiccated and swathed canola harvested 14 DAT had lower green count and less total damage than canola harvested 7 DAT.
Effect of Sharpen and Valor applied pre-harvest on canola yield and seed quality • Brian Jenks, Jordan Hoefing, and Gary Willoughby • North Dakota State University • Ed Davis • Montana State University
Objectives • Determine the effect of Sharpen and Valor applied pre-harvest on canola yield, seed moisture, and seed quality compared to diquat and swathing.
