In a comment in a Q&A with the director of the excellent short science fiction film Laura un Vineta, a fellow called Will Long tried to identify a short story which was probably from the '50s or '60s:
Your video brought to mind a science fiction short story that I read more than fifty years ago. An alien ship crashed in the cornfield of a lonely, but kindhearted farmer. The farmer finds and buries the crushed body of the sole occupant. Somewhat resembling a corn plant itself, the creature is regenerated from the burial site. And the farmer takes it into his home and raises it to maturity; whereupon, the alien repairs it ship and leaves to return to its home world. However, before it departs, it removes something resembling a large, gem-like marble from its own body and leaves it with the farmer. Even though it knew its own journey through the interstellar distances would be harder to endure without its "companion" (the gem), the alien gave it to the kind farmer to ease his loneliness.
I actually thought it was called "The Companion" or something similar. However, my browser searches on science fiction of that theme did not produce the result I had hoped. It was popular enough that the story later appeared in a book anthology—I read it first in one of the 1950's or early 60's pulp magazines such as "Analog" or "Galaxy"—and I read it again about twenty years ago.
I had a bit of a look myself, but there are too many well-known stories involving aliens and farmers that aren't this!
