Abstract in EnglishAmong the different olive cultivars, 'Shengeh' olive trees have a poor yield, due to the incomplete flower bud development and increment of staminate flowers in arid and semi-arid regions of Iran. In this experiment, the effect of a modified regulated deficit irrigation regime and foliar nutrition with nitrogen, calcium, zinc, and boron on a flower bud and fruit development in 'Shengheh' olive trees were investigated. Two experimental factors contained the irrigation regimes-continuous deficit irrigation (60% of the water requirements) (Control) (I-60),-I-60 + increasing the irrigation to 75% of the water requirements during flower initiation (I-60 + I-75init),-I-60 + increasing the irrigation to 75% of the water requirements during olive flower induction (I-60 + I-75ind), and I-60 + increasing the irrigation to 75% of the water requirements at both time (I-60 + I-75init + I-75ind); and foliar nutrition-without treatment (control), and foliar nutrition with 2% urea fertilizer; 2% Ca-EDTA chelate, 9.5% Ca; 0.2% Zn-EDTA chelate and 0.2% boric acid, during flower initiation (FNinit), flower induction (FNind) and both time (FNinit + FNind). The results indicated that the increment of irrigation water to 75% of the water requirements during flower initiation along with foliar nutrition at both times had significant influence on the increment of shoot and inflorescence length and perfect flowers with ovary rate 3-4 developed ovules by 56.9%, 39% and 118.9%, respectively. Also, this treatment had the highest increment of water productivity and fruit oil content by 184.2% and 64.8%. According to the principal component analysis the increment of shoot length, perfect flowers with ovary rate 3-4 developed ovules and inflorescence length had significant and positive correlation with the fruit yield and water productivity in 'Shengeh' olive trees. This deficit irrigation strategy could be recommended for olive orchards under arid and semi-arid and sub-tropical regions with the same flower bud development problems.
