Which yield monitor was used? Does this monitor require multiple calibration loads, and were these loads taken at differing flow rates? Did you get actual measurements of the grain weight for 300mm and 100mm swaths?
In my experience, doing comparisons with yield monitors is best if the flow is kept relatively equal between them. Yes, hybrids and varieties yield differently, but unless the monitor is calibrated over different flow rates (assuming this is using the Ag Leader-based multi-point calibration, not a single point calibration) you will not get consistent results.
Interesting study!
YM is in CR8090. Calibrations have been done over different speed ranges. Not saying YM is 100% accurate - which one is? The initial trial/test was to evaluate stubble height affect on seeding. I expected more cost & more loss (less yield) but the results aren't saying that. That's the reasoning for asking the questions of the YM - I'm doubting the YM data - but am I right in doubting the data from the YM? |
