No, the docs are clear on this:
"If a field has blank=True, validation on Django’s admin site will
allow entry of an empty value. If a field has blank=False, the field
will be required." (http://docs.djangoproject.com/en/dev/ref/models/
fields/#blank)
The key phrase is *on Django's admin site* (although it's true of
ModelForms generally). blank=False is only validated through forms,
not when you create an instance manually.
