OK, here are some. I'm sure there are more out here; these are the
results of a fairly brief search I did in order to post on a discussion
elsewhere. Below are URL's with a brief description following each. As
I copied this out from my text copy, I don't know if the URL's will
come through as links; but if not, you can just copy and paste them
into your browser.

[Ohio State University study, in which their organic tests produced
13% more corn than statewide average yield (most of the statewide
average was conventionally grown) and topped the record-high state
average by 4 bushels/acre.]

[this one is a New Farm article on studies being done at Rodale, which
have been running since 1981; this update is February 07. Organic
yields started lower, then for a long time were equivalent, then from
95 to 06 were higher than conventional.]

This was a study of basmati rice done at Indian Agricultural Research
Insititue in New Delhi, India. Main focus is which organic amendments
were useful, Relevant sentences to this purpose:
The rice grain yield (4.0 t ha-1) obtained under combined application
of four organic amendments was at par with the yield recorded under
recommended dose of chemical fertilizer application. An interesting
observation recorded was that there was no serious attack of any insect
pest or dis-ease in organically grown crop.

[from university of michigan, news release, "organic farming can feed
the world";
study by UMich researches Ivette Perfecto and Catherine Badgley says
yields almost equal in developed countries and production could double
or triple in developing countries with organic methods]

[a study in India on groundnuts; organic produced 22% higher kernel
yield than cv, as well as other advantages. reported at the 18th World
Congress of Soil Science, 2006, in Philadelphia PA] [groundnut in this
case I believe means peanuts]
