Olive cultivation is relatively speaking, easy. It requires no specific
farming care and the most difficult thing is collecting the fruit.
It has been calculated that the gathering of olives takes 60% of the
total cultivation costs of olives!
The harvesting
of olives used to be done by hand. The olives were allowed to drop
and then they were collected. For those olives which didn’t
fall, the tree was shaken or hit with a stick until they did and then
the women, who usually had this tiring job, collected them and put
the fruit in baskets or panniers as can be seen in ancient Greek and
Byzantine pictures. This method does not produce a good quality of
oil. The traditional way of harvesting olives in areas of large production
was the one using the stick. Special sticks were used to beat the
trees so that the olives fell into special tarpaulins or nets that
had been placed under the tree. In some areas with relatively small
levels of production, it was customary to “pluck” the
branches, in other words, to pull the olives off by hand and place
the fruit in big baskets. This is probably the best method as you
then do not bruise the olive, but this way would be impossible for
large-scale harvesting.
Recent
years have seen the appearance of some machines for harvesting purposes.
These use the idea of a mechanized stick beating the tree, thus helping
production to increase. There are small, plastic sticks which rotate
on the machinery. They release the olives from the branches and the
fruit fall down onto the prepared nets. Olives were taken to the oil
press in large sacks in the old days. However, they lose their value
if kept in these sacks for many days. It has therefore been established
that olives need to be pressed one or two days after having been harvested.
Nowadays, olives are transferred in plastic boxes, which do not bruise
or press the fruit and are taken to the press on the same day they
are collected.
