- Method / resource Multiple regression models predicted the effects of deficit irrigation and fertilization on citrus water productivity, partial fertilizer productivity, fruit quality and yield, with R2 of 0.71-0.98.
- Intervention effect More fertilizer during stage III improved citrus water productivity, with a peak at an irrigation amount of 280 mm.
- Intervention effect More fertilizer during stage III improved soluble sugar content, with a peak at an irrigation amount of 322 mm.
- Intervention effect More fertilizer during stage III improved vitamin C content, with a peak at an irrigation amount of 306 mm.
- Association Soluble sugar and vitamin C contents increased as irrigation amount decreased and fertilization rate increased during stage IV.
- Observation Optimal irrigation amount during stage I was 28–36 mm.
- Observation Optimal irrigation amount during stage II was 74–93 mm.
- Observation Optimal irrigation amount during stage III was 304–334 mm.
- Observation Optimal irrigation amount during stage IV was 151–197 mm.
- Observation Optimal fertilizer (N/P2O5/K2O) application rate during stage I was 98/155/98–123/195/123 kg/ha.
- Observation Optimal fertilizer (N/P2O5/K2O) application rate during stage II was 213/187/307–271/239/392 kg/ha.
- Observation Optimal fertilizer (N/P2O5/K2O) application rate during stage III was 400/398/631–473/470/746 kg/ha.
- Observation Optimal fertilizer (N/P2O5/K2O) application rate during stage IV was 17/101/251–21/123/306 kg/ha.
