|Abstract: ||The effect of deficit irrigation (10% ETc) on olive tree growth, production, oil quality
and natural vegetation from a traditional olive grove, with natural cover crop between rows, in
southern Portugal, was assessed during 2010/2011.
The diversity of natural vegetation and the influence of irrigation in the present
species were low. The most plant species were annuals.
Significant differences on the vegetative growth between treatments were not found.
Nevertheless, the number of fruits was significantly lower in rain-fed conditions. This result
demonstrated that water stress could significantly reduce the number of flowers by
inflorescence, the fruit set or the canopy area. Consequently, because of the less
competition of fruits, it had higher weight, oil yield and its ripeness was more precocious.
However, the yield was significantly higher in the irrigation treatment due to the higher
number of fruits.
The irrigation had no influence on the chemical characteristics of olive oil. However,
sensory olive oils from rain-fed conditions treatment were more fruity, bitter and spicy. Even
so, any treatment had negative impact on the commercial value of produced oils, both
classified as „„extra virgin‟‟.|
