- Observation SCU gave the highest top dry weight, followed by AS, AC and U.
- Intervention effect N up to 200 mg kg -1 as U, AS and AC significantly increased growth.
- Intervention effect SCU significantly increased shoot growth.
- Intervention effect Zinc fertilization did not significantly affect rice growth.
- Intervention effect N and Zn applications increased their uptake and concentration.
- Observation AC produced the highest Zn concentration.
- Observation SCU produced the highest Zn uptake.
- Intervention effect N and Zn generally increased leaf area.
- Observation SCU gave maximum leaf area.
- Observation NYE declined with rising N rates as U, AS and AC.
- Observation NYE increased up to 200 mg N kg -1 as SCU.
- Observation ANR increased up to 200 mg kg -1 as U, AS and AC, then declined.
- Observation ANR increased with increasing SCU N level.
- Observation NPE decreased with increasing N rates across sources.
