depends what you mean by "improve."
it's a fungus that infects the plant and turns the kernels into grotesque grey galls. most folks in the U.S. do their best to keep it out of their corn. the stuff is pretty tasty, though, and folks who grow corn where corn came from (Mexico) are happy to see it.
so sure, it does improve corn production.
