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.
