Well, we dug the potatoes Monday. Final tally was 18 bushels of perfect potatoes, and another 2 bushels of cuts/damaged. Hired kid took those home- with 11 people in his family, they can eat them before they go bad. For a blight year, it wasn't bad... normally, we'd expect around 24 up to even 30 bushels off that amount of seed potatoes, but this year sucked. We had almost 1/3 of the certified seed NOT SPROUT, which cut down the potential yield from the beginning. We were able to keep up with the weeds and got them hilled well in a timely manner, which is probably the big reason we didn't get many blighted tubers. (we did haul a 5 gallon pail of really stinky ones back to be burned, but that's a minor loss to late blight)
Onions were worse, thanks to a very late planting, poor fertilization (one bunch I planted in a raised bed made 1/2 bushel all by itself- if the others had done that well, I'd have had 15 bushels of onions!) As it was, I got 4 bushels, on top of all the sweets we've been eating fresh since early August. I got all those pulled yesterday, and once the wet spell coming tomorrow goes through, I'll spread them all out on a tarp and cure them for a few days before storing.
Littledeb... I planted fingerlings one year, and won't ever do it again. Yes, they produce a lot of tubers. But they're mostly small, and even the bigger ones are awkward buggers to peel. We didn't see any major benefit in flavor, etc over some of the nicer round tuber varieties we always plant. If you want lots of small tubers, plant your regular varieties closer together.
