Yeah, I've heard of this stuff and even went so far to research it. Don't go to the Federal Grant Site unless you want to waste A LOT of time and come up empty handed! After researching for a couple hours I have concluded that you have to in one of a handful of states in order to have any shot at grants. Usually the grants are done on a state level and not a federal level.
They can be found through the agricultural organization of your state usually. If memory serves Ohio, Virginia, and about 3 other states were the only ones that had any kind of significant grant program for beekeepers. There are able 10 more that offer limited grants or offer grants for beekeeping RESEARCH. Usually all that money gets gobbled up by universities (the folks who wrote the grant in the first place.)
Mr Conner in this month issue of the ABJ makes some mention of grant money being used to promote queen rearing in my native West 'by god' Virginia.
So evidently there are funds available and it doesn't look like the end users are in anyway doing anything that might be misconstrued as research. You need not have PhD stuck behind your name to obtain grant money.
