CS vs 750a: The Penultimate Post?

I've just had the data in for ear and grain counts. I have multiplied them up using an assumed TGW (thousand grain weight) of 45g. I'm going to go out on a limb and say they will not be very representative, although I hope very much to be proved wrong!I think harvest will be in roughly 10 days. I have one concern at this point which is there has been a lot of spring germinated black grass at the bottom (heavy) end of the field. I am going to have to try and select a strip for cutting the trial plots that does not have any BG in it, because it is at levels that will affect the yield. I think this will be possible, but it will probably mean not cutting in exactly the same areas the the plant counts have been done in. Luckily there are no weeds at the other end of the field, so we should get on well there.
