This is "broadleaf" tobacco, air drying in a barn with open shutter doors.  The tobacco flower is missing  because this type of tobacco is primarily grown for the purpose of making cigars.  The flowers or "suckers", as they are called, are periodically removed at various stages in growth, in order to keep the plant from growing tall and to promote wide leaf growth instead.  The leaves are used as outer wraps for cigars. The entire plant is harvested and 'hung' to dry slowly over a few months, then the leaves are "hand stripped" and packed flat for shipping to tobacco manufacturing companies.
