noun

• (agriculture) The planting of two or more crops in the same place.
• (sociology, uncommon) A multiculture; a polycultural society, sometimes especially one in which multiple cultures exist without one dominating.
  "What we have here is not a 'multiculture' as it is represented in multiculturalism, not a pluralist order of discrete patches of culture, all somehow, 'equally valid' within the polity, but—to form a Greek/Roman Creole—a polyculture, or at any rate a collection of cultural entities that are not (a) discrete and complete in themselves; (b) that are not in any sense 'intrinsically' 'equal'; and (c) are active together and hence bound up with change."
