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 soil moisture content was recorded maximum in treatment T1(100% ETc) whereas, soil potential was recorded maximum under T10 (no irrigation) during both the years. The maximum fruit weight (206.45 and 208.29 gram), fruit length (10.37 and 10.40 cm), fruit breadth (6.31 and 6.33 cm), fruit volume (213.87 and 216.56 cm3) and specific gravity (1.03 and 1.04 g/cc) were recorded in T7 (PRD 75% ETc + F) during both the years 2017 and 2018, respectively. Mango trees treated with PRD 50% ETc and fertigation recorded maximum TSS (20.42 and 20.50 0Brix), titrable acidity (0.22 and 0.22 %), total sugars (15.25 and 15.30 %), reducing sugars (3.71 and 3.73 %), non reducing sugars (10.96 and 10.99 %). The application of PRD 75% ETc + F resulted in maximum fruit set (0.96 and 0.98 %) and yield (47.02 and 97.11 kg/tree) compared to all other treatments and maximum fruit drop percent was found in treatment (T10) 86.24 and 87.13 %. The maximum water use efficiency was recorded in PRD 50% ETc + F (T9).
