142 FORAGE CROPS. 



level land, but there may be some few instances when 

 raised drills would be superior. When sown for the 

 grain, for ensilage, for soiling food or for hay they 

 are put in with the grain drill. But they may also 

 be planted with a corn planter or a bean planter. It 

 is customary to make the rows about thirty inches 

 apart. If the crop were grown for pasture the 

 rows could be made considerably closer, under some 

 conditions, but not so close as to preclude cultiva- 

 tion, except such as may be given with the har- 

 row. There may be instances when it would be 

 advisable to broadcast a crop of soy beans. When 

 the rows are thirty inches apart, from two to four 

 pecks of seed will suffice per acre. If the rows were 

 placed closer, as for growing forage, more seed 

 ought to be used. 



The soy bean and the cowpea should grow 

 fairly well together. The beans would furnish 

 some support to the peas. But further experiments 

 are required before it can be claimed that this method 

 of growing them has any decided advantage over 

 growing the beans separately. At no time should 

 the seed be sown earlier than the corn planting sea- 

 son, and north of the 4Oth parallel of latitude it 

 ought to be planted later. But south of that line, 

 good crops have been grown, the seed of which was 

 not planted until July. In the north, early varieties 

 only should be sown, and even in the south very late 

 varieties ought not to be used. 



Cultivation. The cultivation suitable for the 

 soy bean is about the same as that which ought to be 

 given to the cowpea (see Page 136). A harrow 

 with the teeth aslant can be used with advantage 

 before the beans are up, and also in some instances
