In small plot yield studies variable stands are a common problem. Because a perfect stand is rare, researchers are often faced with making adjustments to small plots for data analysis. The current standard of 18in of compensation has been called into question.  How should this be done to gain an accurate picture of the variety in a given environment? What is the effect of skip on total plot yield, and what is the minimum skip that needs adjustment?  A multi-year study was conducted in multiple environments to help address this problem.
