Results in Yield Environment	% of Average		Results in Predominant Soil Type	% of Average
High:	100(162)		Heavy:	101(14)
Medium:	100(67)		Medium:	101(147)
Low:	97(17)		Light:	91(5)
Non-Rotated:	102(28)

Numbers above are variety's yield versus plot average expressed as %. The higher the number the better. The number in parentheses is number of plots in that set.

Yield for corn: High > 225 bu/acre, Medium is 225 to 150 bu/acre and Low < 150 bu/acre
Yield for soybeans: High > 70 bu/acre, Medium is 70 to 40 bu/acre and Low < 40 bu/acre

Soil: Heavy is high organic matter/water capacity (heavy silt), Light is low organic matter/water capacity (sand or gravel)
