Abstract

The present study was carried out during two successive seasons (2011 and 2012) on "Picual" olive trees (Oleaeuropaea L.), at a private orchard of El-Arish located on El-Arish Airport Road, North Sinai Governorate, Egypt to study the effect of some growth regulators (Gibberellic acid (GA3) at 75 ppm, Ethephon at 150 ppm, Naphthalene Acetic Acid (NAA at 50 ppm) and antioxidants (aqueous extract Roselle (Hibiscus sabdariffa), Cumin (Cuminumcyminum) and Ginger (Zingiberofficinale) on leaf nutrient content, as well as fruit and oil qualities of picual olive trees. The trees were sprayed with growth regulators three times, at late February (one month before beginning of the flowering), during full bloom period and 10 days after fruit set. While, Different antioxidant applications were sprayed transaction in three stages: the first application was applied after the first contract and prior to flowering, the second application wasz applied after two weeks from first spraying, and the third one was applied two weeks before harvest. This study were exposed to proper statistical analysis of variance for a randomized complete block design RCBD (two factors split plots) with three replicates and each replicate was represented by two trees. The results showed that NAA treatment recorded the highest value of N% content, while, Ethephon treatment had the highest values of P and K. The highest values of N% were found with H.sabdariffa and C. cyminum extract gave the highest increase in P and K% during both seasons. GA3 and H. sabdariffa  gave the highest values of fruit and oil yields as well as Fruit physical and chemical properties in both seasons.
