GROWING THE CROP. 



Soil Preparation. 



Land is prepared for sorghum in much the same 

 way as for corn. The land may be plowed either in the 

 fall or spring. Fall plowing should be done as early as 

 possible and left rough until spring. As early as pos- 

 sible in the spring the land should be harrowed and lat- 

 er, when the weeds are started, it should be double disc- 

 ed, lapping half to avoid ridging the ground. The land 

 can then be left until seeding time when it should be 

 rolled and given another harrowing. Spring plowing 

 should be harrowed as promptly as possible and then 

 treated the same as fall plowing. 



Method of Seeding. 



Tests have been conducted at Brookings and Eure- 

 ka for the purpose of determining the best method of 

 seeding. The following table shows the results obtain- 

 ed.

METHOD OF 'SEEDING TEST FOR SUDAN GRASS AT EUREKA 



The above data indicates that the largest yield of 

 Sudan grass can be obtained by seeding in drill rows six 

 or twelve inches apart and that if one desires to grow it 

 as an intertilled crop, the best yield is obtained by sow- 

 ing two rows six inches apart with 36 inches between 

 each pair of rows for cultivation. 



The closer the drill rows were placed, the finer was 

 the quality of the forage as the stems grew smaller and 

 the proportion of leaf to stem was greater. While it is 

 true that under favorable moisture conditions both yield 

 and quality of forage is improved by solid planting, the
