Other claims from this paper (7)

Method / resource In an apple trial, accumulating four years of crops gave a lower coefficient of variation than two years.
Method / resource Covariance adjustment by previous crops was useful, with two years of previous crop as good as four years.
Method / resource Adjustment by trunk girth was less successful than previous-crop covariance but could be recommended in conjunction with previous crop.
Method / resource Number of fruits was a more variable record than crop weight.
Method / resource Removing positional variation by analysis of variance did not have a major effect in reducing variation.
Method / resource Multi-tree plots proved effective in reducing variation, since adjacent tree crops are not highly correlated.
Method / resource Covariance adjustment of multi-tree plots was not successful.
