- Association Plant height did not have a specific influence on tomato yield.
- Association Stem girth did not have a specific influence on tomato yield.
- Association Branch number positively affected tomato yield.
- Intervention effect Inorganic fertilizer plus full irrigation produced 7691.4 kg/ha tomato yield in 2020.
- Intervention effect Inorganic fertilizer plus full irrigation produced 9009.9 kg/ha tomato yield in 2021.
- Observation No fertilizer at 50% deficit irrigation yielded 1423.9 kg/ha in 2020, the lowest treatment.
- Observation No fertilizer at 50% deficit irrigation yielded 1739.2 kg/ha in 2021, the lowest treatment.
- Intervention effect Organic compost gave the highest tomato yield at both deficit irrigation levels.
- Intervention effect Deficit irrigation had higher crop water productivity than full irrigation.
- Observation At 50% deficit irrigation, compost had highest CWP of 4.54 kg/m 3 in 2020.
- Observation At 50% deficit irrigation, inorganic fertilizer had highest CWP of 5.52 kg/m 3 in 2021.
- Observation No fertilizer at full irrigation had lowest CWP of 1.37 kg/m 3 in 2020.
- Observation No fertilizer at full irrigation had lowest CWP of 1.67 kg/m 3 in 2021.
- Method / resource Measured and simulated yields agreed strongly across irrigation and nutrient management.
- Method / resource The tomato model generally overestimated measured yield.
