USDA's Sustainable Agriculture Research and Education (SARE) program has
funded several projects looking at weed control, but one in particular
looks at tilling after dark. In 1994, a Cornell scientist received SARE
funds to conduct the following project:
"Integrating New Cultivation Technology and Photocontrol of Weeds
to Reduce Herbicide Use in Vegetables"
View a brief summary of results at
http://www.sarep.ucdavis.edu/cgi-win/sare/sare.exe/id=1014
The summary includes contact information for the principal investigator.
Through SARE's Sustainable Agriculture Network, (SAN), we published an
entire book on weed control, Steel in the Field: a Farmer's Guide to Weed
Management Tools. Steel in the Field shows how today's implements and
techniques can control weeds while reducing -- or eliminating --
herbicides. See http://www.sare.org/htdocs/pubs/

> During discussions in our local sustainable/organic group there
>have been
>people suggesting that the final tillage operation should be done in late
>evening or after dark. Weed seeds are light sensitive for germination, and
>there will be fewer weeds germinating if the tillage is done in the dark?
>Has there been any replicated studies done in this area? Also any farmer
>experience that could be shared?
