Hi Kathy, here is how I go about doing the turnips. On the previous farm I had a rotation going, where I would plow up the fading hay/grazing fields, and put them into turnips for 2 years, then replant to an alfalfa blend (or let the natural native grass seed bank germinate..that one was a very nice clean farm). The plowing and fertilizer gave me improved yields on those fields for the next four or five years. The rotation was about 7 years long. I do not have a stitch of farm machinery here. So I hire a neighbor to do the field work. Generally there is someone within 10 miles who both owns a tractor and is willing to do custom work. On my new rented farm, the current owner already has a rotation with corn and beans going. He's agreed to do a rotation of corn/beans/turnips before replanting the field. This saves me the cost of plowing, so I only have to hire him to disk the field up and cultipack the seed in. Seed is spread via the fertilizer truck (it is mixed in with the fertlizer). Turnips do love their nitrogen. I am planting July 15 to Aug 1 for early September grazing. Turnips do require moisture. in this area the biggest obstacle would be if the fall is dry. Despite suffering through a 100 year drought, and this year, the driest fall since 1889, we seem to always have a crop albeit a bit stunted thanks to our heavier soils.
This year's cost was $2800 including rent, seed, tillage, and fertilizer on 12.5 acres. This produced enough turnips to finish 200 lambs for six+ weeks in a record dry fall. I figure the same cost in purchased feed would be an estimated $6,000. Gains on turnips are lower, in part because they are 90% water. 12-15 pounds per lamb per month are typical. But transitioning them to hard feeds would require a month long set back, which needs to be figured in to the equation. there is no setback transitioning to turnips.
I have heard of attempts to plant turnips without tillage and the results described have not encouraged me to give that a try. Hard ground does not help a turnip.
On the previous farm, I had access to two 40 x 60 foot open front sheds. I tried lambing in them several times over a 19 year period. The losses lambing indoors were actually higher, as were the labor requirements and expenses, that they offset any benefits an earlier lambing might have bestowed.

ps on the tillage end, one benefit is that turnips require planting during what is usually a pretty slack time in the schedules of local farmers. All other planting is done, and there typically is a pause in the hay making schedule. So finding help is usually not difficult so long as someone is within a reasonable distance. The hardest part is introducing the concept....it will probably sound very foreign to whomever you talk to and might require a long discussion to convince them you are not loonie.
