Abstract
Increasingly, traditional Bramley orchards in Ireland are being replaced with high density orchards.
These new orchards have a much higher capital charge against them which must be repaid with higher yields.
In order for growers to determine which planting density/rootstock combination suits their orchard and financial conditions best, it is necessary to commercially evaluate different planting densities.
In 2000, a range of different densities was planted: M.9’s at 672, 961 and 1492 trees per ha and M.27’s at 1279, 1492 and 1957 trees/ha (imperial spacings were used to suit the local industry). Over the first four growing seasons, yield has steadily increased.
The value of the crop at the end of year four was higher than the cost of production during year four for all planting densities.
