Other claims from this paper (19)
- Intervention effect Cd at 50 mg/kg soil drastically reduced onion fresh and dry weight, with further decreases at higher levels.
- Intervention effect Cd at 50 mg/kg soil drastically reduced fenugreek fresh and dry weight, with further decreases at higher levels.
- Intervention effect Ni at 50 mg/kg soil slightly decreased onion yield, and 100 mg/kg or higher significantly decreased it.
- Intervention effect Ni at 50 mg/kg soil slightly decreased fenugreek yield.
- Intervention effect At 100 mg Ni/kg soil and above, onion yield decreased significantly.
- Intervention effect At 100 mg Ni/kg soil and above, fenugreek yield decreased significantly.
- Intervention effect No onion growth occurred at 400 mg Ni/kg soil.
- Intervention effect No fenugreek growth occurred at 400 mg Ni/kg soil.
- Intervention effect Zn at 50 mg/kg soil slightly increased onion yield, while higher levels reduced yield.
- Intervention effect Zn at 50 mg/kg soil slightly increased fenugreek yield.
- Intervention effect Higher Zn levels reduced onion yield.
- Intervention effect Higher Zn levels reduced fenugreek yield more than onion yield.
- Association Fenugreek root and leaf concentrations of applied elements increased linearly with dose.
- Observation Zn uptake was highest, followed by Cd, Ni, then Pb.
- Observation Roots accumulated more of the elements than leaves.
- Observation Onion tissue Cd at ten percent yield reduction was 6 ppm.
- Observation Fenugreek tissue Cd at ten percent yield reduction was 1.5 ppm.
- Observation Overall phytotoxicity ranked Cd above Ni above Pb above Zn.
- Association DTPA-extractable soil elements rose as applied-element levels rose after crop harvest.
