Abstract

Within water-saving irrigation strategies employed in agricultural production, deficit irrigation strategies are proposed as an effective response to address water scarcity inherent in stone fruitcultivation in semi-arid climates. This study focused on apricot fruits of the 'Mirlo Rojo' variety from a research orchard located in Cieza (Murcia), subject to four irrigation strategies: full irrigation (100% irrigation according to crop evapotranspiration, TA), 66% irrigation (33% reduction in irrigation, TB), 33% irrigation (66% reduction in irrigation, TC), and 100% irrigation reduction (TD). Theirrigation reductions were implemented during the final stage of fruit development. The three irrigation reduction treatments (TB, TC, and TD) showed lower fruit weight and caliber compared to the control irrigation treatment, but there were no significant differences in these parameters among treatments employing deficit irrigation. The 100% irrigation reduction (TD) resulted in lower pulp yield, but no differences were observed among the other treatments when performing the ANOVA and Kruskal-Wallis tests. Fruits from deficit irrigation strategies presented higher total soluble solids content and maturity index compared to full irrigation fruits; however, there were no significant differences in titratable acidity. Preliminary findings suggest that most physicochemical parameters in 'Mirlo Rojo' apricots are not affected by water restriction. This situation presents the opportunity to produce high-quality apricots with significant water savings, aligning with sustainable production frameworks.
