- Intervention effect Herbage and oil yields of Mentha arvensis increased significantly with N fertilization up to 100 kg N/ha.
- Intervention effect Herbage and oil yields of M. piperita increased significantly with N fertilization up to 100 kg N/ha.
- Intervention effect Herbage and oil yields of M. spicata increased significantly with N fertilization up to 100 kg N/ha.
- Intervention effect Herbage and oil yields of M. citrata increased significantly with N fertilization up to 150 kg N/ha.
- Intervention effect Plant height increased with nitrogen application in the mint species.
- Intervention effect leaf: stem ratio increased with nitrogen application in the mint species.
- Intervention effect oil content decreased with nitrogen application in the mint species.
- Observation The estimated economic optimum nitrogen dose for M. arvensis was 167 kg N/ha.
- Observation The response equation predicted M. arvensis oil yield of 190 kg/ha at the economic optimum.
- Observation The estimated economic optimum nitrogen dose for M. piperita was 153 kg N/ha.
- Observation The response equation predicted M. piperita oil yield of 103 kg/ha at the economic optimum.
- Observation The estimated economic optimum nitrogen dose for M. spicata was 145 kg N/ha.
- Observation The response equation predicted M. spicata oil yield of 50 kg/ha at the economic optimum.
- Observation The calculated optimum fertilizer rate for M. citrata was 225 kg N/ha.
- Observation The calculated M. citrata oil yield at that rate was 193 kg oil/ha.
- Intervention effect Oil quality did not vary appreciably with nitrogen fertilization.
