Purple-top and Yellow Globe. The Cow Horn is 
highly recommended as a catch-crop, because it 
roots more deeply, thus bringing to the surface 
plant-food from lower layers. 
As a catch-crop, turnips may be sown after 
potatoes, tomatoes or other early crop, or seeded 
in corn at the last cultivation, serving both to con- 
serve plant-food and provide a succulent feed. 
The yield varies widely. When grown primarily 
for forage and the soil liberally fertilized, as high 
as thirty tons per acre are recorded. The turnip 
does not seem to be able to obtain the necessary 
phosphates so readily as some other crops; there- 
fore it is especially benefited by applications of 
superphosphates. Lands in good condition in 
other respects may grow a maximum crop of 
turnips with additions of phosphate alone, applied 
at the rate of 250 pounds per acre of acid phos- 
phate. Under average conditions, however, an 
application of nitrogen and potash should accom- 
pany the phosphate. 
Turnips may be sown either broadcast or in 
drills; when seeded as catch-crops the broadcast 
method is practiced and seed used at the rate of 
two to three pounds per acre. Where grown for 
forage, they should be in drills, seeded at the rate 
of one pound per acre, and thinned to six inches 
in the row, and cultivated as other crops.
