194 FORAGE CROPS 
Sorghum-and-cowpeas, or sorghum-and-soy- 
beans, make an exvellent summer forage, providing 
the sorghum is seeded rather thickly and harvested 
before it has nearly reached maturity. 
The quantity of seed recommended for all these 
combination crops is one-half that used when each 
of the crops is grown singly. 
MIXED GRASSES AND CLOVERS 
On most farms in the dairy sections of the 
country, timothy, red-top and clovers (both red 
and alsike), and timothy and clovers are two mix- 
tures generally used for pasture and hay-making. 
When the purpose of growing forage crops is pri- 
marily to supplement natural pastures, this crop 
of mixed grasses and clovers serves a most excel- 
lent purpose in supplying the need in emergencies. 
In. many localities, the grasses are seeded in the 
fall with field crops, as with wheat or rye, and 
the clovers are seeded in early spring, either with- 
out covering or with light harrowing. 
When immediate and large returns are impor- 
tant, seedings may be made without cover-crop in 
the late summer or early fall. The best time of 
seeding has been found to be from the middle of 
August to the first of October, depending on the 
locality. At the New Jersey Experiment Station, 
many tests have been made as to methods and
