The profitability of regulated deficit irrigation (RDI), sustained deficit irrigation (SDI), and SDI with partial root zone drying(PRD) strategies was compared to that with full irrigation (FI: 100% crop evapotranspiration) in drip-irrigated Kinnow mandarinin northern India. RDI was scheduled with two irrigation levels: no irrigation and 50% crop evapotranspiration (ETc.) imposedin the early fruit growth period (EFGP) andfinal fruit growth period (FFGP) singly and in combination, whereas SDI wasscheduled at 50% ETc and 75% ETc with and without the PRD technique. The highest fruit yield was recorded with FI, whichwas statistically on a par (p>0.05) with that with SDI at 50% ETc with PRD (PRD50). Economic-based comparison shows thatall the treatments were economically viable since their profitability (net return, INR 137 000–1 300 000 ha-1and benefit–costratio, 2.1–14.3) were viable. The net return generated with PRD50was statistically (p>0.05) at par with that generatedwith FI. However, the benefit–cost ratio and economic water productivity calculated with PRD50were found to be significantly(p
