 ^{a}An approximate LSD (5%) for total area on day 21 is 0.804; an approximate LSD (5%) for total area on day 51 is 6.67, for fresh weight is 0.520 and for height is 1.69; an exact LSD for the density index is 0.193.
 ^{b}The predictions are for the average value at the centre of a row or lane.
 ^{c}The standard errors give an indication of the variability of the predicted averages, but LSDs are required to judge whether pairs of predicted averages are different. The standard errors are proportional to the fitted standard deviations for the different locations/tactics.
 ^{d}The coefficients of variation (CV) measure the variability of individual plants.
