| Sumario: | In order to determine the existing relationship
between crop load and yield, expressed
as those processed for canning (fruit weight
between 100 and 250 g, canned in halves) or
puree, a trial was set in a commercial orchard
on Bowen, Andross and Ross cling peaches
in Mendoza, Argentina. Trees grafted on Nemaguard,
vase shape trained, and planted at
6 x 5 m (333 plants/ha) were used. Hand thinning
was performed 20 days after the beginning of pit
hardening, leaving a range of crop load between
750 and 1350 fruits per tree in Bowen and Ross
and between 850 and 1400 fruits per tree in
Andross. Average fruit size was determined as
well as total yield or expressing it as share for
industrial use (canning or puree); crop value was
also evaluated. All these variables were tightly
related to crop load showing similar responses
for different cultivars. As crop load increases total
yield increases but average fruit size decreases.
Yield for canning increases as crop load
increases up to a maximum of 1200 fruits/tree;
after such crop load canning yield decreases. A
curvilinear relationship was also found between
yield for puree and total yield. Given the fruit size
and yield responses to increasing crop load, fruit
thinning, among other management practices, is
highly determinant to maximize canning peach
profitability for the growers.
