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.

Linus Pauling was an amazing scientist who nevertheless went off the rails with his vocal claims on vitamin C. The same goes for other accomplished scientists who descended into promoting nonsense claims like Margulis and W.D. Hamilton. In no way am I comparing Heinemann to great scientists, I am simply saying that being accomplished in your own field does not grant you immunity from making nonsense claims in another field. Heinemann talks complete nonsense when it comes to GMOs and has for many years.
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. )
If you think that it is fine to include 10 years of data before GMOs were used as part of the GMO data then that speaks to your own intellectual integrity and standards.
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.“
As Chris Preston shows, when Heinemann's data is done properly it shows:
Yield increases per year by standard regression (ha/hg/yr) for Maize:
US 1961-1995: 1073 +/- 113
WE 1961-1995: 1392 +/- 95.08
US 1996 - 2011: 1273 +/- 231.4
WE 1996 - 2011: 887.4 +/- 334.8
While it is not significant due to the large error bars, it is thoroughly dishonest to claim that the results show WE has had the same, or marginally greater, yield increases.

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).
"Maize Lines Are More Diverse Than the Human–to–Chimp Comparison"
"Springer et al. [6] compared B73 to another modern inbred and report an
unprecedented level of structural diversity—differences in gene copy number and hundreds of genes present in only one line. Soderlund et al. [3] also point out that maize has many genes not found in other higher plants. What selective forces in both the progenitor wild species and modern cultivar have elevated
gene generation and allelic diversification (from length polymorphism, single nucleotide changes, and transposon insertion/excision events) orders of magnitude higher in maize than most other plants and animals?

Heinemann is not an authority on this subject. He is simply talking out his ass. In 1970 Southern corn leaf blight ravaged the US, by the next year conventional breeding methods had completely ended it. With biotechnology techniques such problems are corrected even faster and better.
While it is true that Mexico, with it's diversity of corn varieties, did not suffer from the same corn blight their yields for 1970 were 1 MT/HA, compared to the US with 5 MT/HA (DURING the time of this terrible blight). In 2013 Mexico has risen to 3 MT/HA, compared to 10 MT/HA. So I don't see any benefit for the US moving to a system where they produce 30% of the US' current yields.

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.
The most interesting thing about that result is that after 3 hours of various google and scientific literature searches it seems Heinemann completely made that number up. It bares zero resemblance to anything I could find. France is still ranked roughly fourth highest in the world in pesticide usage. The only journal article I could find that included insecticide use in France reported a 1% reduction from 2001 to 2004.
If a country managed to produce reductions anywhere near the supposed claim that Heinemann made about France, it would be found every where. Greenpeace would be trumpeting it. It would be all over the place in newspapers, scientific journals, Government of France websites. But the claim exists no where except for being vomited out of Heinemann's mouth.
Heinemann is a notorious anti-gmo liar.
