Would planting corn in arid regions increase the likelihood of rain/precipitation?

I just read about 'corn sweat' for the first time and, y'all, my mind was blown and replaced with sooo many questions. The articles and links that pop up when googled all state sweat from corn, and like plants, can increase humidity in an area making humid areas more so (as in the American Midwest). If this is true, then can we assume it also applies to non humid areas? If it does, then, basically, my main question is the one from the title- Would planting corn in arid regions increase the likelihood of rain/precipitation? 

Thank you!

The answer is technically yes, but not realistically.

Corn can only give off water that it has absorbed, so you'd need to be providing it with a ton of extra water anyway. 

So sure, if you plant a few million acres of corn in some dry area and provide it with the billions of gallons of water it requires, you might slightly increase the chance of the atmosphere reaching saturation and causing rain.

But you're probably just better off using that water for whatever you needed directly, at far less of a loss.
