described above. All the other
cultivation was the same during
the year. The yield production, the
number and weight of the cluster,
the accumulated sugar content and
the acid content were measured.
All the parameters were differentiated
by the length of the
hardened wooden part of the cane
by the harvest time. In this way
three categories were obtained;
under 30 cm, 30 to 60 cm and
above 60 cm. The results are
presented in the table 1.
Economic evaluation
of BBCS
The economic evaluation was
carried out in California, for in
earlier times large areas were
cultivated according to BBCS,
while other training systems were
available for comparison. In Table
2 we have summarized all the data
which we received from our US
partner.
Finally let us mention a few
advantages from our experience:
Removing buds is easier than
pruning canes.
We do not need to collect
canes or to use any other tool to
cultivate into the soil.
– Thin canopy easy to reach.
– The shoot growth is a short
period, less expensive
chemicals (contact fungicide)
are sufficient.
– High yield with good
quality.
– Limited to no canopy
management during vegetation.
– Higher resistance and
regeneration after hail
damage (short film is
available on www. agroinform.hu
about these
results).
The biggest advantage could
be the full mechanization of the
technology.
