GH:  You've totally missed the point. I DON'T WANT TO CONTROL ANYTHING.
     What I want to know is, what is the Standard Deviation of plant
     growth in the "real environment" when we are talking strictly about
     a crop of geneetically identical plants? 
       Now, somebody in agriculture must KNOW the answer to this, say
     for potatoes, or onions or some other asexual crop plant.
