Where is this research?
Nothing formal but most from just browsing around the net, do a search. Also a bit of personal experience with blocked coulters, not scientific (or intentional!) I agree but gives a good indication non the less.
I remember talking to other farmers a few years ago who almost to a man agreed that the move to narrow spacings (usually from an old MF30 drill) made sweet fanny adams difference to their yield.
