Harvest prep starts in the spring

December 1, 2014

KEY PRACTICE: Reducing harvest losses starts with strong crop establishment, adequate fertilization, early weed control and frequent scouting.

KEY RESEARCH: Liu, C., Agriculture and Agri-Food Canada (AAFC), et al. “Evaluation of On-Farm Crop Management Decisions on Canola Productivity.” Canadian Journal of Plant Science (2014).

Watson, P.R., Alberta Research Council, et al. “Canola Harvest Management Study.” Canola Agronomic Research Program project (2008).

A 2014 study by Chang Lui et al reported 24 percent greater seed yield when canola was straight combined instead of swathed. The sample size was small — only six growers in this study straight combined compared to 55 who swathed. But the study brought up an interesting point: a portion of the success growers who straight combined enjoyed may have been due to the other management strategies, such as the use of preseed weed control, which they all used.

Similarly, it has been estimated that a portion of the seed yield increase attributed to straight combining is due to the extended time the seeds are allowed to mature before the crop is cut. Deliberate management techniques, such as accurately assessing the stage of seed development, can be crucial to the success of straight combining experiences.
