Abstract:
The present investigation was carried out during two successive seasons 2009 and 2010 to study the effective concentration and application time of potassium nitrate (KNO3) on vegetative growth, nutritional status, yield and fruit quality of Picual olive trees under sandy soil conditions. The obtained results showed that, foliar application of potassium nitrate at 4 % after final fruit set or pit hardening improve the vegetative growth, nutritional status especially in the second season and the productivity in both seasons. While sprays potassium nitrate at 4 % after pit hardening gave the best values of fruit quality and flesh oil content of Picual olive fruit in both seasons of the study.
