CLOSE DRILLS AND BROADCASTING. 



In humid regions and under irrigation, drilling with a grain drill is 

 the most satisfactory mbthod of seeding Sudan grass for hay except 

 when seed is very expensive. Even in the dry regions this method 

 gives nearly as good results as the cultivated-row plan. Sudan grass 

 seeded in close drills requires no cultivation, the plants mature more 

 uniformly and have finer stems, the roots are less troublesome later 

 on, and the hay is not as dusty as that grown in cultivated rows. 



The ordinary wheat drill is the best machine for this work. It dis- 

 tributes clean Sudan grass seed uniformly and covers it evenly. 

 Most wheat drills sow this seed at about the same speed as wheat; for 

 example, when set for 2 pecks of wheat per acre the drill may be
