Table IV shows that there was a marked decrease in the number 
of stalks per plant where the plants were crowded. From the yields 
obtained on these plats, particularly those shown in Table II, it 
appears that this reduction of tillering is advantageous from the 
standpoint of crop returns. As shown in Table IV, a large number 
of the stalks found on May 15 failed to mature heads. The produc- 
tion of nonbearing stalks or tillers uses soil moisture without any 
compensatory results. This being true, it seems desirable to reduce

the number of stalks per plant, and it appears that this can be readily 
done by crowding the plants within the row, as is shown in figures 
3, 4, 5, and 6. 
EFFECT OF SPACING ON MATURITY. 
One of the most important requirements for the successful pro- 
duction of grain sorghum in the San Antonio region is early and 
uniform maturity. This is necessary, in order that the crop may 
escape the ravages of the sorghum midge.
