What is the name of a big farm on which crops are raised by workers who live there?

There isn't one specific name for a large farm where workers live on-site. However, here are some terms you could use, depending on the context:

* Plantation: This term is often used for large farms, especially in the past, that grew cash crops like cotton, tobacco, or sugar and relied on a workforce that lived and worked on the land.

* Collective farm: This term is associated with agricultural systems in socialist countries, where land was collectively owned and worked by a community.

* Agricultural estate: This term is more general and can be used for large farms owned by a single individual or family.

* Ranch: While typically used for livestock, some large ranches also grow crops and have their own workforce living on-site.

The specific name may vary depending on the location, the type of crops grown, and the specific history of the farm.
