This farm operation support system makes it possible to easily convey, during farm work with farm equipment, information about work performance or a work plan corresponding to said farm work. This farm operation support system performs farm operations by linking a first piece of farm equipment mounting a data collection device (2) which collects the operation performance when farm operations in a farm field are performed, and a second piece of farm equipment which performs farm operations other than those performed by the first piece of farm equipment. This farm operation support system is provided with: a database (3) which, for each farm field, aggregates the operation performance collected by the first piece of farm equipment an operation plan calculation means (4) which calculates an operation plan for each farm field on the basis of the operation performance in the database (3) and a data output means (5) which outputs the operation plans corresponding to said farm fields to the second piece of farm equipment performing farm operations in a farm field.
