THE NON-SACCHARINE SORGHUMS. 65 



luxurious growth is sought, then the seed should be 

 planted in rows and cultivated. The latter sys- 

 tem will be more commonly adopted where moisture 

 is deficient. 



When sown on the broadcast plan, the aim 

 should be to plant with the ordinary grain drill all 

 the tubes being in use, or only every alternate tube, 

 as may be desired. When sown in rows far enough 

 apart to admit of cultivation being given, the same 

 implement may be used, but of course various other 

 seed planters may also be used. The rows should be 

 from thirty to, say, forty-two inches distant, accord- 

 ing to circumstances, except in the case of teosinte, 

 which should, at least when grown for certain uses, 

 have a greater distance between the rows. But the 

 most suitable distance for placing the rows when 

 growing these crops can only be determined with 

 precision in each locality by actual experience in 

 growing them. 



The time for planting will depend on the 

 location and the character of the weather. It would 

 be a mistake, however, to plant the seeds before the 

 weather had become steadily warm. The plants are 

 less able when young to endure cold than corn in 

 nearly all its varieties, and than sorghum in its 

 leading varieties. At the Minnesota university 

 experiment station low temperatures prevailed dur- 

 ing two or three weeks subsequent to the planting of 

 these crops in 1897. Corn in some of its varieties 

 made a fairly good start notwithstanding, and the 

 Early Amber variety of sorghum maintained its hold 

 upon the soil. The non-saccharine sorghums with- 

 out exception only partially germinated, although
