CLOSE DRILLS AND BROADCASTING. 
In humid regions and under irrigation, drilling with a grain drill is 
the most satisfactory method of seeding Sudan grass for hay except 
gives nearly as good results as the cultivated-row plan. 
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. 
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
