RELATIVE YIELD OF CANNING PEACH TREES AT DIFFERENT DENSITIES UNDER THREE GROWING SYSTEMS
Orchard efficiency [canning size fruit yield ( >60mm dia.) - t/ha] and fruit bearing potential [trunk cross sectional area/ha (TCA/ha - m2/ha)] were related to both tree size (cm2 TCA) and crop load (fruit number per cm2 TCA). The interaction of growing system and planting density (trees/ha) on yield efficiency (kg fruit/TCA) also affected this relationship. An optimum tree density for each growing system was revealed when accumulated canning yield (t/ha) and yield efficiency were considered in relation to fruit bearing potential. The influence of growing system on tree size and crop load significantly affected fruit size at harvest since yield of canning size fruit (kg/tree) was inversely related to crop load.
