- Intervention effect Planting density did not significantly affect leaf fresh weight.
- Intervention effect Deficit irrigation at 50% ETc reduced leaf fresh weight.
- Intervention effect Higher planting density reduced average bulb size by 12%.
- Intervention effect Higher planting density increased marketable bulb number by 21% to 33%.
- Intervention effect Higher planting density increased marketable yield by 7% to 14%.
- Intervention effect Deficit irrigation tended to reduce bulb number and bulb size.
- Intervention effect At 75% ETc, yield fell by 8% to 13%.
- Intervention effect At 50% ETc, yield fell by 19% to 27%.
- Intervention effect Planting density and deficit irrigation had no significant effect on soluble solids, pungency or quercetin.
- Recommendation Growers could adjust planting densities to target high-value bulb sizes.
