STUDY ON PLANTING DENSITIES OF PEACH AND NECTARINE CULTIVARS ON DIFFERENT ROOTSTOCKS

After six years of observations the yielding efficiency was reported of Early Coronet peach cultivar grafted on Damas 1869 rootstock, at 4 x 1.25 – 2.00 – 2.50 m distances, and on seedling rootstock, at 4 x 1.50 – 2.50 – 3.50 m distances; of Early Sungrand nectarine on Saint Julien GF 655–2 at 4 x 1.25 – 2.00 – 2.50 m distances, and Independence on seedling at 4 x 1.50 – 2.50 – 3.50 m distances.

Of particular interest seem to be the yielding results achieved with a greater density of trees per hectar, compared to the other two cases, and this applies to all scion-rootstock combinations tested.

On the other hand, negative aspects are due to a loss of ripening precocity of about one day, compared to larger distances, and to a smaller fruits caliber.
