This study addresses water-saving irrigation strategies, including regulated deficit irrigation (RDI) at 75% and 50% crop ETc and partial root-zone drying (PRD) at 75% and 50% ETc to investigate the response of the mango (Mangifera indica L.) drip system in the field on a sandy loam soil during years 2017 and 2018. Results revealed that the date of appearance of panicle, full bloom was recorded earlier in the treatments T6 i.e (RDI 75% ETc + F) as compared to the treatments not subjected to fertigation i.e both T2 (RDI 75% ETc), T3 (RDI 75% ETc), T4 (RDI 75% ETc) and T5 (RDI 75% ETc) whereas, panicle appearance and full bloom was last (100% ETc) respectively in plants treated with full irrigation (T1) as compared both fertigated and non fertigated plants during both the years, respectively whereas longest duration of flowering was recorded in treatments receiving fertigation i.e T6 (RDI 75% ETc + F). The panicle length (26.57 cm and 25.18 cm) and panicle breadth (13.53 cm and 11.78 cm) was recorded maximum under T7 comprising of PRD 75% ETc + F and minimum panicle length (18.52 cm and 17.37 cm) and breadth (10.88 cm and 9.52 cm) was recorded under T10 i.e no irrigation whereas tree height, spread and stock girth and scion girth was found maximum at T1 100% ETc. The maximum fruit weight, volume and size was recorded in T7 PRD 75% ETc + Fertigation and minimum was recorded in treatment T10 no irrigation. The benefit cost ratio was found maximum under treatment T7 comprising of PRD 75% ETc + F.
