At qepHom 2014, the {yobta' yupma'} was given for "harvest festival".

A phrase which has something to do with some novel, but that's not important.

Can someone use the {yobta'} on its own for "a/the harvest", or does it have to be used as a set phrase {yobta' yupma'} ?

I find set phrases disturbing
