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 Accumulating six years of crops gave little advantage over four years in reducing the coefficient of variation.
- Method / resource Covariance adjustment by previous crops was useful, with two years of previous crop as good as four years.
- 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.
