Water scarcity is one of the major causes of low productivity and decline of citrus orchards. Deficit
irrigation (DI)is a recently proposed water saving technique in irrigated agriculture. The impact DI versus
full irrigation (FI: 100% crop water requirement) was evaluated in citrus orchards under a hot sub-humid
climate of central India. Two DI strategies applied to citrus trees were DI1: 20% FI during initial fruit
growth period (IFGP) + 40% FI during finalfruit growth period (FFGP) + FI during rest ofthe period, and DI2:
70% FI during entire irrigation season. Fully irrigated trees had the highest vegetative growth. However,
DI1 produced 18% higher fruit yield with superior quality fruits, resulting 30% improvement in water
productivity under this treatment compared to FI. Fruit yield prediction based on vegetative growth and
leaf physiological parameters of the trees using principal component regression analysis technique was
found reasonable accurate. These results suggest for adoption of DI1 in citrus orchards of central India
and elsewhere having similar agro-climate of this study region
