Sure KathyP, there's as much advise about farming/gardening out there as there is about beekeeping, likely more from my own experience, really. Now c'mon, what do "you" usually advise folks when given so many options in beekeeping?
In our area (many areas actually) root crops (when still operating, our farm business name was "the Root Seller"), onions, most legumes (food and seed), potato's, Cole crops, many fruits (we have apples, wild plumbs, cranberries, cherries, currents and blueberries) to mention a few, can/do exceptionally well with only limited efforts once soil has been enriched with organic matter. As said, variety is the spice of life. Do to a very late frost last year, June 19 I think, we had 'no' apples last year, but we had back ups.
We use a small (6x8) greenhouse (and our house windows) to start many plants and then plant many varieties under hoops (and have at ready, boxes full of blankets to protect from early and late frosts), and which assist in lengthening our growing season by as much as 60 days, some years. We learned that if we wanted to keep our seeds 'true' we'd have to 'block' our bees from pollinating some of them (peppers, for instance).
If we only limited our garden to ten or so crops, we wouldn't starve (too many deer, grouse, squirrels and turkeys around ;)) but our taste buds would be in revolt for sure ;). So, we typically grow at least 2 varieties, and as many as 6 different 'varieties' of carrots, beets, turnips, rutabagas and parsnips alone. When still operating we sold 22 varieties of garlic (seed from all over the world).
I should mention that we never had more than five (2 just with garlic, but that was before NAFTA) acres planted and that our current 'enclosed' garden is roughly 1 1/2 acre. We've always had plenty to eat and donate.
And This hasn't even touched on what's available wildcrafting herbs and other edibles :-D.
