Intervention effect Sole caraway gave the highest fruit and volatile oil yield per faddan.
Intervention effect The highest potassium rate significantly increased yield parameters of caraway and onion compared with control.
Intervention effect The intercropping system (1:2) was more efficient than sole cropping in competition indices when combined with the highest potassium rate in most cases.
Observation Caraway was dominant in aggressivity estimation.
Observation Onion was dominated in aggressivity estimation.
Recommendation The mixture of caraway and onion seems promising for sustainable crop yield advantages with limited external inputs under Sharkia Governorate conditions.
