THE NON-SACCHARINE SORGHUMS. 63 



between the rows than the shorter varieties, as, for 

 instance, Jerusalem corn. 



When grown for pasture the seed may be sown 

 broadcast and covered with the harrow, but when 

 thus sown more seed is required, as some of the plants 

 will fail to germinate, nor will they come upsoevenly, 

 since the seed is buried at uneven depths. The sub- 

 sequent use of the harrow will tear out a goodly 

 number of plants, since at first they are less robust 

 than corn plants, and less firmly rooted in the soil. 

 And if grazed while the plants are still young and 

 tender, more of them will be pulled up by the roots. 

 It is preferable, therefore, to plant the seed with the 

 grain drill, and with all the tubes in use ; but under 

 some conditions, as, for instance, those in which the 

 probable rainfall is deficient, it may be advantageous 

 to plant the seed in rows far enough apart to admit of 

 cultivation other than harrowing. 



When the seed of these sorghums is sown broad- 

 cast to provide pasture, not less than one bushel per 

 acre of seed is required. But under conditions that 

 are very dry, much less than that amount may suffice, 

 since the plants if too numerous will pine for want 

 of moisture. W r hen planted with the grain drill with 

 all the tubes in use, three pecks of seeds should be 

 ample ; and when the rows are made distant enough 

 to admit of horse cultivation, a few quarts of seed 

 per acre will be found sufficient. 



Cultivation. If sown broadcast, the only culti- 

 vation that can be given to these crops would be to 

 harrow them, and the harrow would have to be used 

 with extreme caution. It should of course be light, 

 and when so used the teeth should have much of a 

 backward slant, otherwise too many of the plants
