I assume the goal is to reduce fertilizer costs for the canola by getting some N from the Lentils. I am not sure if it really works like that or not.
This is my understanding of how the pulse thing works. The Nitrogen gain the year after growing pulses is not from the N that is released from the nodules like I had thought, but is just more N available from your organic matter, because it takes less N to decompose pulse straw than it does other types of straw. So I am real skeptical that you will get any N benefit from your Lentils to put towards your canola.
Now other benefits from the intercropping may be entirely useful, such as different rooting depths, different growth rates at temperature, different growing days, so one might mature sooner and quit using moisture, less disease pressure, etc.
Perhaps your goal is to have the lentils creep up the canola and have less disease in the lentils. If so, then having the canola emerge later than the lentils would be very benefical as lentils are so slow to get going.
Is the canola mixed with innoculant just to allow you to meter out the low rates of canola?
I assume clearfield canola and lentils. If not, would mustard be a better fit? Lower N requirements, yellow mustard is very shatter proof (not sure about lentils), usually pays a little better than canola.
