THE NON-SACCHARINE SORGHUMS. 6 1 



land will not drift, the same treatment should be 

 given to spring plowed land in any case, in areas 

 where moisture is not plentiful. 



Where commercial fertilizers are applied, it is 

 common to sow them at the same time as the seed. 

 The seed and the fertilizer, however, should not be 

 deposited by the same drill tube, lest the fertilizer 

 should injure the seed, because of too close proximity 

 to it and in quantities too large. When it is desired 

 to sow the sorghums thickly, as for pasture, it would 

 be easily practicable to apply the fertilizers in the 

 broadcasted form and just before the drilling in of 

 the seed. The kind of fertilizer to apply must be 

 determined chiefly by the needs of the land. 



Sowing. Since all the non-saccharine sor- 

 ghums are natives of the south, they cannot endure 

 low temperatures. It is useless to plant them in a 

 soil not yet warm, or before the arrival of distinc- 

 tively settled warm weather. If planted sooner, 

 either the seed will not sprout at all or it will make 

 but a feeble and sickly growth after it has sprouted, 

 if indeed the young plants do not perish outright. 

 At the Minnesota University experiment station it 

 has been noticed, first, that seed corn of varieties 

 grown north until acclimated will sprout under con- 

 ditions much more adverse than the more tender 

 southern varieties of corn, and that the growth of the 

 young plants will be correspondingly more vigorous. 

 Second, that the early growth of varieties long 

 acclimated is more vigorous than that of varieties but 

 recently acclimated. Third, that these varieties of 

 corn will grow with a fair amount of vigor under 

 conditions where the seed of Early Amber sorghum 

 with all its ruggedness would fail to germinate, or
