- Observation Synthetic fertilizers released 84 to 89% of total N after 28 days.
- Observation Chicken manure pellets released 52% of total N after 91 days.
- Observation Composted cow manure released 13% of total N after 91 days.
- Intervention effect Broccoli yield was generally higher under synthetic fertilizers.
- Intervention effect Broccoli N content was generally higher under synthetic fertilizers.
- Intervention effect Glucosinolate concentrations were generally higher under synthetic fertilizers.
- Intervention effect At 800 kg ha−1 N, sinigrin under organic fertilizer matched the synthetic fertilizer treatment.
- Intervention effect At 800 kg ha−1 N, glucoiberin under organic fertilizer matched the synthetic fertilizer treatment.
- Intervention effect Fortnightly N application reduced broccoli head weight relative to basal and weekly application.
- Intervention effect Glucosinolate concentrations did not significantly differ among N application timings.
- Intervention effect The study found no evidence that N supply rate affects broccoli glucosinolate concentrations.
