two to three weeks. This will secure a succession of green feed 
for summer and fall feeding that will serve to make the farmer 
independent of short pastures and will keep the stock in a vigor- 
ous, thrifty condition (Fig. 25). Rape is also sown in drills, about 
30 inches apart, with the plants two to three inches apart in the 
row, either with spring grain or with corn just before the last 
cultivation. This will furnish an abundance of green forage for 
fall feeding. Rape may be cut or pastured from eight to ten weeks 
from the time of seeding, when it will be 12 to 15 inches high.

The variety of rape generally sown is Dwarf Essex, which is a 
biennial. Nearly all the seed of this variety on the market is im- 
ported. The seed of bird-seed rape, which is an annual, is some- 
times sold as Dwarf Essex, and care should, therefore, be taken to 
buy seed from reputable seedsmen only, as the former variety is 
worthless for forage purposes. 
Rape contains about 14 per cent dry matter and 2 per cent 
digestible protein, its nutritive ratio being about 1:4.3. Both on 
account of its relatively high water content and its narrow nutri- 
tive ratio, it will not give satisfactory results when fed alone, but 
should be supplemented with grain feed, preferably with low- 
protein feeds, such as corn and other cereals, wheat middlings, or
