No interactions present.
That does not look anything like a pea plant to me. It may be some kind of test crop if they have been planted.
There are yellow flowers on the top and leaf shape would suggest a type of Bean but as Refugee said definably not pea.
looks like the foliage of Melilotus if I had to take a guess
I'd agree with that. Why not enter this as a 'Might be this' ID?
