Twenty years ago this was not much of a debate in canola. Now it is one of the more interesting decisions on the farm, and the right answer is genuinely different from one operation to the next.
Worth saying plainly: there is no settled winner. Growers running similar acres in similar soil with similar equipment come down on opposite sides, and both are right for their own operation.
The case for swathing
You control the timing. Swathing at the right seed colour change sets the crop up to dry evenly. Straight cutting means waiting for the whole field to come to you, and fields are not uniform.
It evens out an uneven crop. A field with variable staging, or a reseeded patch, or a low spot that is two weeks behind, is easier to manage in a swath than standing.
Earlier start. Swathed canola is ready to combine before the same crop standing, which matters when the forecast is short.
Less shatter risk from one direction. A swath on the ground is not exposed to wind the way a standing crop is, though it has its own exposure.
The case for straight cutting
One pass instead of two. The labour and fuel saving is real and easy to calculate for your own operation.
Standing crop dries faster after rain than a swath lying on wet ground, which can turn a two day delay into a five day one.
No swath to move. A swath in a strong Saskatchewan wind is a problem that straight cutting simply does not have.
Pod shatter tolerance has changed the maths. The varieties available now hold their pods considerably better than what was in the ground fifteen years ago, which removed much of the original argument against standing canola.
The honest comparison
Most comparisons of the two come down to yield, and the yield difference in most trials is smaller than people expect, with results going both ways depending on the season.
Which means the decision is usually not about yield at all. It is about:
- How many acres you need to cover and how many days of good weather you typically get
- Whether you have the labour for a second pass
- What your fields look like for uniformity
- Whether you have a header suited to standing canola, which is not the same header you would use in cereals
- Your own tolerance for the particular kind of risk each approach carries
The header question
If you are considering straight cutting, the header matters more than the combine. A draper with a good crop lifting system handles standing canola very differently than an auger header, and the difference shows up directly in header loss, which in canola is the loss that gets overlooked.
Extended knife systems, vertical cutters for tangled crop, and reel position all become more important than they are in a swathed crop.
This is worth a conversation before buying either way, because a straight cutting setup that is wrong for your crop will produce exactly the shattering losses that made people nervous about straight cutting in the first place.
Many operations do both
The split approach is common and sensible: swath the fields that are uneven or at risk, straight cut the ones that are uniform and standing well. It keeps the swather in the yard rather than selling it, and gives you a choice when the season turns out different from the plan.
If you are moving toward straight cutting for the first time, trying it on a portion of the acres rather than all of them is the low risk way to find out how it suits your ground.
