Mr Bowern, of Rutland Court, Peterborough, struggled to pull the gigantic vegtable out of the ground at the weekend and at first thought it was going to be a "little stumpy one".
He said: "I couldn't believe it when I pulled it out. It is definitely the biggest one I have ever seen or grown, so I quickly measured and weighed it. I have grown 10 inch carrots before, but not like this."
Mr Bowern took up an allotment in Burton Street with his wife, Crisanta (61) who comes from a keen farming family in Portugal.
And the 69-year-old who also grows turnips, parsnips, cabbages and garlic, believes the secret to growing gigantic carrots is from a packet of special seeds brought in Portugal. He said: "The packet said gigantica, but we didn't think they would get that big."
