- Intervention effect At 75% ETc, deficit irrigation gave 8-9% lower fruit yield than full irrigation.
- Intervention effect At 75% ETc, deficit irrigation reduced vegetative growth relative to full irrigation.
- Intervention effect Irrigation water use efficiency at 75% ETc was 81-83% higher than under full irrigation.
- Intervention effect Fruit under 75% full irrigation were heavier than under full irrigation.
- Intervention effect At 75% full irrigation, fruit TSS, ascorbic acid, total sugar, and reducing sugar were higher than under full irrigation.
- Intervention effect At 75% full irrigation, fruit acidity was lower than under full irrigation.
- Intervention effect Fully irrigated plants had superior leaf and stem water status.
- Intervention effect Full irrigation gave the maximum net photosynthesis, stomatal conductance, and leaf transpiration.
- Intervention effect Deficit irrigation at 50% ETc gave the highest leaf water use efficiency.
- Intervention effect Fully irrigated plants had higher leaf concentrations of N, P, K, Fe, Mn, Cu, and Zn.
- Observation Nutrient availability in soil was higher under full irrigation.
