Abstract The main objective of this study was to acquire agronomic knowledge about the effects of irrigation with saline reclaimed (RW) and desalinated DESERT (DW) water and different irrigation strategies: control full irrigation (FI) and regulated deficit irrigation (RDI) on leaf nutrients, tree growth and fruit quality and yield of almond trees in pots. Our results showed that RW had the highest concentration of some valuable agronomic nutrients such as N, but also of phytotoxic elements (Na and Cl−). Na leaf concentration on RW treatments reached toxic levels, especially under RDI, and toxicity symptoms were shown. Regarding tree growth, cumulate trunk diameter on RW-RDI was significantly lower than on the control treatment and shoot growth was reduced from the beginning of the irrigation season in RW treatments. Maximum yield was reached on RW-FI, 18% higher than the control treatment. However, RDI strategies influenced negatively on yield, being 23% less in RW and 7% less in DW although water productivity was not significantly reduced by water stress. These findings manifest that the combination of RW and RDI can be a promising future practice for almond irrigation, but long-term studies to establish suitable management practices must be developed.

ABSTRACT: The objective of this work was to evaluate the gas exchange, leaf temperature, yield and water use efficiency in 'Tommy Atkins' mango under irrigation deficit strategies. The experimental design was randomized block, with seven treatments with regulated deficit irrigation (RDI) under micro-spray and five treatments with partial root-zone drying (PRD) under drip irrigation. The treatments on RDI consisted of application of 100, 75 and 50% of ETc at the stages S1 (beginning of flowering to fruit set) S2 (fruit development) and S3 (fruit physiological maturation). The treatments on PRD consisted of application of 100, 80, 60 and 40% of ETc, in the same three stages, alternating the irrigation side every 15 days. The regulated deficit irrigation causes less negative interference in gas exchange than the partial root-zone drying, and the climate factors affect the gas exchange and leaf temperature of 'Tommy Atkins' mango more than the regulated deficit irrigation. The partial root-zone drying irrigation with 60 and 40% of ETc causes a decrease in the 'Tommy Atkins' mango yield. The regulated deficit irrigation up to 50% of ETc, applied at the fruit maturation stage, maintain the yield and water use efficiency.
