zea tillers

the bear paw maize in my yard is beginning to tiller ( first and third photos )..the teosinte has been tillering ( second and fourth photos )...the dense yellow number two in the last two photos has not and, probably, won't...the teosinte will produce multiple ears of seeds before the season ends...i am curious to see if the bear paw maize will...provided the squirrels do not cut the experiment short ( and i expect they will )...there may be a few plants in the industrial field that produce more than one ear..many will not...part of the process that allows them to be planted so closely together is a reduction in yield per plant..a trade off...fewer ears, more plants, aiming for an increase in bushels per acre...it is feedstock after all...more is better, right?
