Results obtained in a field experiment showed a high influence of irrigation and nitrogen fertilization on the activity of peroxidase, while acid phosphatase activity showed only small differences. The peroxidase activity depended to a large degree on the leeks growth stage. Maximum peroxidase, catalase and - in some cases – acid phosphatase activity were found at nitrogen doses higher than optimal for the plant growth and yield
