Sometime in the corn hybrid trial plot we do not get competitive plant stand i.e. less plant stand due to several factors. During the yield calculation it creates some biasness in data. I generally try a principal that in a plot (with significant less stand) less stand contributes yield due to increased sink size and number and side by side it reduces yield by reducing number of years. I used the following formula: Adjusted yield = plot yield + [per plant yield X 1/2 of (ideal plant stand/plot - actual plant stand/plot)] assuming that 50% of the less stand will be contributed by the increased sink (ear size & number of years/plant increase) and rest 50% I add mathematically. It will be a great help if someone can suggest me whether I am correct or any other more efficient formula.
