I am reading a table related to production of rubber; the title of the table is Productions By Holdings And Estates. In this context, what is the difference between holdings and estates?
Where is the table you are reading? Where does the document originate? If it's rubber, it may be about India?
In South Africa, a "Holding", or more properly, and "Agricultural Holding", is something between a farm and a town property, and can be used for agriculture, such as growing rubber.
An "Estate" has no legal meaning as far as property goes, but may be taken to mean an large contiguous piece of land made up of more than one registered property, but probably all owned by the same person/s or legal entity/ies, for a common purpose (such as, for example, growing rubber).
