The Mediterranean region's agriculture is predicted to be severely impacted negatively by climate change. In the primary production region of southern Tunisia (34°43’N, 10°41’E) in olive orchard submitted to different treatments: Rain-fed, drip irrigation with saline water (FI) : EC = 7.5 dS/m at 100% of crop evapotranspiration (ETc), alternate irrigation (PRD) with saline water at 50% of ETc and switched every 30 days, regular deficit irrigation (RDI) with saline water at 50% of ETc, drip irrigation with tap water (TW) : EC=2.46 dS/m at 100% of crop evapotranspiration (ETc), with predicted temperature increases, the effects of climate change and salinity on the floral performance of olive trees were assessed from 2015 to 2017 and the vegetative growth and yield were evaluated over the period. As results, while conserving water in comparison to FI and TW, PRD produced high values for internodes length (1.68 cm) in 2016 and an annual shoot elongation (2.5 cm) in 2015. When comparing flowering (RF) and fruit-setting (RS) rates, olive trees under PRD outperformed those under RDI and FI with (RF=67.52% and RS=7.81%) in 2015. For olive trees exposed to RDI, PRD, and FI, the fruits per unit length were statistically similar in 2015. The use of the PRD technique (50% ETc) yielded good results with an average of 2.96(kg/m3) in our study both quantitatively and qualitatively.

The current study aimed to determine the effect of single and dual inoculation with arbuscular mycorrhizal fungi (AMF) on soil quality and mineral content of young olive plants. One-year-old self-rooted olive plants (Olea europaea L.) of the cultivar Chetoui were inoculated with different AMF: (i) Glomus deserticola (AMF1); (ii) Gigaspora margarita (AMF2) or (iii) a 1:1 mixture of G. deserticola and G. margarita (AMF3). After one year of symbiosis, the obtained results showed that AMF played an important role in improving the fertility of the experimental soil by increasing the organic matter and the micro-nutrients contents (Nt, P and K+), as compared to control soil. Such effect induced an improvement in marco- and micro-nutrient contents in leaves and roots of all inoculated olive plants. The beneficial effect of mycorrhizal association was more important under inoculation with mixed species of AMF.
