B.A'P'E (Brassica JVapns). Fig. 2079. In recent years 

 this has become an important forage plant. The name 

 Rape includes several varieties which are grown for 

 two purposes : ( 1 ) for seed from which oil is expressed ; 

 (2) for the purpose of furnishing animals with succu- 

 lent feed during late summer and aiitumn, when pas- 

 tures become bare. Varieties used for the latter pur- 

 pose usually do not produce seed in this climate the same 

 season, though they are usually classed with annuals. 

 Dwarf Essex is an example of the kind used for soiling- 

 (green feeding) purposes. Rape is of considerable im- 

 portance to the fruit-grower as a cover-crop. The seed 

 germinates readily, will often grow where a clover catch 

 is impossible, and furnishes excellent sheep pasturage 

 late in the season. When grown strictly as a soiling 

 plant the tops are cut and hauled to the feed-lot or 

 stable. Dwarf Essex Rape much resembles a ruta- 

 baga turnip at first. It is like a rutabaga with an exag- 

 gerated leafy top and without a swollen fleshy root. 

 Rape is a cool weather plant and may be grown in al- 

 most any part of the United States by sowing it at the 

 proper time. As a cover-crop in the orchard in the East 

 it may be sown as late as September 15 with good re- 

 sults. It is an excellent pioneer plant in the work of 

 renewing humus in worn-out lands. In the Middle 

 West, where shade is needed. Rape is used as a nurse 

 plant for clover wlien the latter is sown in orchards in 

 midsummer. Turnips may be used for the same purpose.
