I'll volunteer to be a farm site for a replicated trial of this sort. Send me
the seed and I'll see what happens on my Pennsylvania Farm. I'll plant 3 random
comparisons of 4 row strips the whole length of a given field to give an
alternative to the small plots. I have experiance doing these sort of
experiments, with other research, over the years.
