e1“to study the effect of different nutrient and water treatments on the growth and yield of tomato”
e2“Compared with FW, FW1 and FW2 had yields not significantly different from grower control treatments”
e3“they saved 35% to 46% of the nitrogen (N) fertilizer, 40% to 54% of the phosphorus (P 2 O 5 ) fertilizer, 19% to 35% of the potassium (K 2 O) fertilizer, and 15% to 21% of irrigation water”

Other claims from this paper (10)
- Intervention effect FW1 and FW2 formula fertilizer and water treatments gave tomato yields not significantly different from grower control treatments
- Intervention effect FW1 and FW2 saved 35% to 46% of nitrogen fertilizer compared with FW
- Intervention effect FW1 and FW2 saved 40% to 54% of phosphorus fertilizer compared with FW
- Intervention effect FW1 and FW2 saved 15% to 21% of irrigation water compared with FW
- Intervention effect FW1 and FW2 gave higher economic profits than FW and FP treatments
- Intervention effect Formula treatments reduced soil electrical conductivity under tomato in solar greenhouses
- Intervention effect Formula treatments reduced the accumulation of soil nitrate, available P and available K under tomato
- Observation Soil nutrients under tomato remained above optimal levels
- Mechanism Obvious N surplus in the tomato greenhouse was attributed mainly to high N input from manures
- Recommendation Greenhouse tomato nutrient and water use could be reduced while maintaining the same yield
