- •
Deficit irrigation at 50% ETc at early fruit enlargement period (RDI50) could save 24% water in ‘Kinnow’ mandarin cultivation.
- •
The fruit yield of the plants under RDI50 was statistically at par with that under full irrigation (FI).
- •
Fruit quality of deficit irrigated plants was superior to that with fully-irrigated plants.
- •
The reduction in photosynthesis rate is relatively less than the reduction in transpiration rate of plants under RDI50 compared to FI.
- •
Principal component-regression has been found as a potential tool to predict the fruit yield of the deficit-irrigated plants.
