The alternate bearing of olive tree

Referring to olive production often say or hear the word “ventema” meaning a rich crop year, or the fact that this year we will not have good production because we had the previous or the opposite. All this has to do with alternate bearing.

The alternate bearing of the olive tree is the fluctuation phenomenon of production every other year without the influence of pathologic or climatic factors. So a year of full fruiting is followed by a year with extremely reduced fruiting.

This phenomenon has been described as physiological activity of olive tree and reflects the capacity of olive trees give more fruit than allowing the forces to the excessive consumption of nutrient and energy reserves of the tree.

This phenomenon can be reduced by the producer with the usage of appropriate techniques of pruning, the perfect watering of olive tree, as the supportive supplement of nitrogen lubricants stocks.
