Effect of Root Pruning on the Productivity of Kensington Pride ackground: oot pruning has been used commercially to reduce tree size and promote flowering and fruiting in tree rops such as apples. It has been particularly effective at reducing vigorous vegetative growth. ensington Pride (KP) normally produces very vigorous vegetative growth throughout six months of the year. s a result growers are faced with the ever-increasing size of trees with reduced yield efficiency. Treatments hat reduce the vigour of KP tend to increase flowering and thence yield efficiency. Current practices to mprove tree productivity, such as the use of plant growth retardants, pruning and irrigation techniques roduce unreliable results. Root pruning offers a non-chemical alternative. A previous trial using root pruning n eight-year-old trees over one season showed improved productivity of trees where tree size was reduced 0 20 40 60 80 100 120 1 2 3 4 5 6 7 8 9 10 Property % f lo w er in g /t re e Control Paclobutrazol Morphactin 0 50 100 150 200 1 2 3 4 5 6 7 8 9 10 Experimental site F ru it y ie ld ( kg /t re e) Control Paclobutrazol Morphactin
