Methods of Reducing Crop Variation in Apple Trials

C. S. Moore; S. C. Pearce Journal of Horticultural Science 1976. doi:10.1080/00221589.1976.11514723

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.

Other claims from this paper (13)

Association Improved perennial ryegrasses were no more competitive toward Kentucky bluegrass seedlings than annual ryegrass.
Observation Improved perennial ryegrasses provided rapid initial cover.
Mechanism Persistence of perennial ryegrasses allowed bluegrass encroachment during the seedling year.
Mechanism Ryegrass seedling competition was not due to seed or seedling excretions.
Association Turf quality with improved perennial ryegrasses exceeded annual ryegrass but was slightly below pure bluegrass.
Association Redtop and creeping red fescue were less competitive with bluegrass than ryegrasses.
Association Turf quality of redtop and creeping red fescue mixtures was similar to pure bluegrass.
Intervention effect Higher seeding rates offered no advantage above 5% PLS.
Association Fall seeded mixtures contained the most Kentucky bluegrass.
Association Summer seedings contained the least Kentucky bluegrass.
Intervention effect Low clipping reduced companion grass competition and allowed transition to bluegrass dominance.
Association Pure bluegrass turf had the best sod strength.
