Why is it when I run this query:
ALTER TABLE pub.dbo.Organ ADD CONSTRAINT fkey_Organ_ParentID FOREIGN KEY (ParentID) REFERENCES Pub.dbo.Organ(ID)

I receive this statment:
Msg 547, Level 16, State 0, Line 2
The ALTER TABLE statement conflicted with the FOREIGN KEY SAME TABLE constraint "fkey_Organ_ParentID". The conflict occurred in database "Pub", table "dbo.Organ", column 'ID'.

Could it be the vaules in ID & ParentID column

it seems like you've some records with values in ParentID which does not correspond to existing ID column values. so either remove them before creating constraint or create constarint WITH NO CHECK option
