Actualy yes and no  here's a great summary : https://www.newscientist.com/article/dn11655-climate-myths-higher-co2-levels-will-boost-plant-growth-and-food-production/

I don't trust that article at all. The links to the areas of the IPCC report if refers to are broken. It's a biased news article and doesn't appear to be properly referenced.

Here's what I've read on the subject.

First one estimates a 33% increase in crop yields due to Co2.

Second also estimates a rise, but states that it's less than expected and so probably won't offset negative effects of Climate Change (but fails to explain what those negative effects are).

The 33% increased your article is reffering to is at 660 ppm. For instance the safe zone is estimated to be 350 ppm we are at 400 ppm and the limit to keep temperature below 2C increase is estimated to be 450 ppm. http://sustainabilityadvantage.com/2014/01/07/co2-why-450-ppm-is-dangerous-and-350-ppm-is-safe/

we'll never have 33% increase in an open environement.
