Accounting for variation in designing greenhouse experiments with special reference to greenhouses containing plants on conveyor systems

Table 2 Summary of differences between locations or tactics for all response variables

^aAn 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.
^bThe predictions are for the average value at the centre of a row or lane.
^cThe 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.
^dThe coefficients of variation (CV) measure the variability of individual plants.
