The term "first fruit" refers to the initial crop that is harvested from a plant. However, there are several other synonyms that can be used to describe this same idea. One term that could be used is "initial yield", which describes the first production of a particular crop. Another term that could be used is "primary harvest", which refers to the first main collection of crops from a plant. Additionally, the term "inaugural crop" can be used to describe the very first yield from a newly cultivated plant. These synonyms provide different ways to describe the idea of the first crop, but all ultimately point to the same concept.
