All experiments are statistically
designed so that the "real" yield differences can be separated from yield
differences that occur by chance. LSD (Least Significant Difference) values are used for
this purpose. When comparing the yield of one variety with the yield of another variety,
the yield difference must exceed the LSD value (higher or lower) to be considered a
"real" difference. It is advisable to use multi-year averages when choosing a
variety or cropping sequence.
