They are a cool season plot and other brassica's that are often planted with them are canola,kale, and rape.
Deer will eat both the top and bottom.
Reach peak production in 90-110 days.
Leaves are high in protein 16-24% and roots are 12-15%, comparable to alfalfa
I've read that turnips will give you the same energy value as corn but for less cost.
There are hundreds of varieties but the most popular for deer are Green Globe, Purple Top, Purple top /White Globe,Samson,Sirius, and White Egg.
The biggest differences are the proportion of bulb to leaf. You can get a lot of leaves and little bulb, little leaves and big bulb or in between.
If late nutrition is not desired you can get a no bulb seed like All Top and Seven Top.
Deer will often leave the field untouched until the first frost then hammer it.
Ive hunted over turnips and saw deer out there from opening day to the last.
a Ph of 6.0-6.5 is best
Loose well aerated soil is best
Sirius,Green Globe, and York Globe grow best in the Midwest according to a University of WI study
Grow best in temps between 40 and 60 degrees
Need 90 to 110 days to grow before frost to reach their potential
Most in the north plant during first part of August
They need 6 hours of sunlight
Seeds should be planted 1/4 to 1/2" deep
Best using either a no-till drill or broadcasting and culti packing after.
Im looking at planting some this year as well so I've been doing alot of research on them.
Hope this helps.
