in zone 6. Can I get a fall crop of broccoli rabe?
If it is possible to get a fall crop, when should I plant? Should I add nitrogen or other fertilizer? Thank you.
Broccoli rape is not a cool season crop. It isn't related to broccoli despite it's name. You can sow seed any time directly into the garden. Here is more growing information. https://www.gardeningknowhow.com/edible/vegetables/broccoli-rabe/broccoli-rabe.htm
