Do you have references for him being a ‘notorious anti-gmo professor’ … rather than just a professor who is against gmo? I did a quick search and he seems to be a respected researcher published in a number of peer-review journals (Food Microbiology, Proceedings of The Royal Society, Food & Chemical Toxicology, … ) and well cited by other scientists.I only made it 3 paragraphs in when I came across this piece a couple days ago. When the author of the piece made it seem as though the lead author of the study in question was neutral towards GMOs and just awww-shucks wound up with those results. Jack Heinemann is one of the most notorious anti-gmo professors in the world with previous anti-gmo junk papers and several very far out there claims. Seems on par with claiming that someone like Fred Singer is neutral on the climate change issue. And it is not like the author of the piece was not aware of this. He has previously been a go-to guy for other anti-gmo pieces of hers. In my view she should have at least had the decency to represent him accurately if she is trying to pass him off as an authority. If a journalist is being deceitful, I stop reading.
As for his paper....I took a look at it, and it seems like a pile of crap to me. Brainster already mentioned suspicion of the claims. Bottom line is for some bizarre reason he chose 1986 through 2010 for a comparison of gmo/non-gmo yield increases....which is pretty stupid as GMO corn was not in use until 1996. Or...actually, pretty smart as it got Heinemann the results he was looking for. If you actually compare the yield increases since 1996 the US comes out ahead of the EU (although it is not significant), while from 1961 until 1995 the EU comes out ahead in terms of average yearly yield increases.

He was actually comparing several crops over that time, some GMO some not. (Incidentally, the post I originally queried was the Central Scrutinizer quoting a farmer asking "Why are people opposed to Monsanto? We get higher yields using a lot less fertilizer and pesticides than we did 30 years ago". So a choice of 1986 was not so bizarre perhaps. )

So far from Heinemann getting the results he was looking for, you seem to actually agree with him? His conclusion from that seems (rather than the ‘pile of crap’ you suggest) fair to me: “These results suggest that yield benefits (or limitations) over time are due to breeding and not GM, as reported by others (Gurian-Sherman 2009), because W. Europe has benefitted from the same, or marginally greater, yield increases without GM. “
If you didn’t read the article beyond the third paragraph there were some other concerning trends that he points out, for example on the genetic diversity of the crops in the US (and gives references to some of the dangers of that).
in 2005, farmers could choose from nearly 9,000 different varieties of corn. The majority (57 percent) were GE, but farmers still had over 3,000 non-GE varieties to pick from. … Within all of those thousands of corn varieties sold, one single variety, Reed Yellow Dent, makes up 47 percent of the gene pool used to create hybrid varieties. All in all, corn germplasm comes from just seven founding inbred lines. More than a third come from one of those seven, a line called B73.
With farmers in nearly every state planting such genetically similar corn, farmers experience booms and busts together. Farmers in Mexico, the birthplace of corn, plant a fantastic variety of corn. The plants differ in color, height, ear size, drought tolerance, maturity time, and more. If bad weather shows up late in the season, the early maturing varieties still provided a harvest. If it’s dry, the drought tolerant varieties survive. If a new disease shows up, some of the corn is bound to have some resistance to it whereas other varieties will be more susceptible to it. Biodiversity acts almost like an insurance system. “
And about the reduction in pesticide use:
“The US and US industry have been crowing about the reduction in chemical insecticide use with the introduction of Bt crops [GE crops that produce their own pesticide],” says Heinemann. “And at face value, that's true. They've gone to about 85 percent of the levels that they used in the pre-GE era. But what they don't tell you is that France went down to 12 percent of its previous levels. France is the fourth biggest exporter of corn in the world, one of the biggest exporters of wheat, and it's only 11 percent of the size of the U.S.
“So here is a major agroecosystem growing the same things as the US, corn and wheat, and it's reduced chemical insecticide use to 12% of 1995 levels. This is what a modern agroecosystem can do. What the US has done is invented a way to use comparatively more insecticide.” Comparatively more than what? "More than it should be!” exclaims Heinemann. “It should be down to 12% too!”
Segnosaur: I’m not sure why he just gives data for France – it is apparently though the largest of the European corn-growing countries. Down to 12% insecticide use for a whole country without GMO, though – seven times the reduction of the US using GMO. Surely an interesting result.
