Other claims from this paper (10)
- Intervention effect Sole-source 11 mM ammonium curtailed tomato growth.
- Intervention effect Sole-source 11 mM ammonium decreased leaf chlorophyll content.
- Intervention effect At 10% of total N, ammonium increased vegetative growth by about 15%, with or without DIC.
- Intervention effect At 10% of total N, ammonium increased fruit yield by about 15%, with or without DIC.
- Intervention effect Low ammonium enhanced fruit taste and flavor.
- Intervention effect Ammonium at 10% of total N inhibited nitrate uptake rates by about 27%.
- Observation Nitrate and ammonium uptake rates were comparable despite different concentrations in feed.
- Intervention effect Increasing ammonium up to 50% of total N had no further significant effect on early vegetative growth.
- Intervention effect Higher ammonium caused high blossom-end rot incidence.
- Intervention effect Even 1.1 mM ammonium reduced calcium and magnesium accumulation in leaves and fruits.
