Other claims from this paper (9)
- Intervention effect A slight decrease in irrigation with increased N supply improved average root diameter, total root length and root surface area.
- Observation The interaction of irrigation and nitrogen was non-significant for average diameter of roots.
- Intervention effect W80 N100 did not change photosynthesis or stomatal conductance compared with the control.
- Intervention effect W80 N100 decreased tomato yield by 2.90%.
- Intervention effect W80 N100 decreased tomato yield by 8.75%.
- Intervention effect W80 N100 increased irrigation water use efficiency by 21.40%.
- Intervention effect W80 N100 increased irrigation water use efficiency by 14.06%.
- Intervention effect Reducing a single factor at W80 N100 and W100 N75 compensated growth and yield of tomato.
- Recommendation W80 N100, with 80% of irrigation water and 15 mM of N fertilization, is recommended for soilless tomato production in greenhouses.
