experience has shown that corn does not do well after rape, unless 

 the land is naturally rich in these substances. Results ol)tained at 

 the North Dakota Experiment Station indicate that the growing of 

 a crop of rape on land that has been sown to wheat for a number of 

 years produces a decided increase in the yield of wheat from the suc- 

 ceeding crop. This is a point of much value in regions where wheat 

 is extensively grown. 



VARIETIES. 



All the varieties of rape that have come into prominence in Ameri- 

 can agriculture are winter or biennial sorts. Dwarf Essex or Eng- 

 lish rape has been most widely cultivated. Recently a variety has 

 I been placed on the market under the name of Dwarf Victoria rape, 

 or simply Victoria rape, which has given excellent results in New 

 England and also in the Northwest, yielding, as a rule, rather better 

 than the Dwarf Essex. At the New Hampshire Experiment Station 

 this variety is reported as yielding nearly 50 tons of green fodder per 

 acre, and yields of 25 to 30 tons per acre are reported from South 

 Dakota and elsewhere in the Northwest. Under average conditions 

 a yield of from 10 to 20 tons or more may be expected from either of 

 these varieties. 



CULTURE. 



Owing to the great variety of ways for utilizing rape and the 

 many places it may occupy in the rotation of crops on the farm, 

 there are numerous methods of culture that may be followed in grow- 

 ing it. When it is grown as the primary crop of the season the land 

 should be prepared by deep and thorough plowing, preferably early 

 in the preceding autumn. In some soils a second plowing should be 

 given in the spring before the seed is sown, but in soils that are nat- 

 urally loose and mellow, such as are found in portions of the North- 

 west, a simple stirring of the surface with a cultivator or disk-har- 

 row will often be sufficient. The land should be well pulverized by 

 harrowing before the seed is sown. When the land needs fertilizing 

 barnyard manure may be applied before plowing in the autumn, or 

 if the land is plowed twice the manure may be spread on during the 

 winter or early spring before the last plowing. Commercial fertili- 

 zers may be applied by harrowing in at the time that the land is be- 

 ing pulverized previous to seeding. Whatever treatment the land is 

 given in preparation for this crop it should be such as to afford a 

 deep, mellow seed bed, as free as possible from noxious weeds. 



SEEDING. 



Throughout the Northern States generally, seeding may take place 

 from the first of June or possibly earlier, to the middle or last of 

 July, according to the season and locality. In the South the seed may
