BROOM-CORN EXPERIMENTS AT WOODWARD, OKLAHOMA. 43 
per cent of suckers, and in the rows spaced 3.5 feet apart the average 
was only 27.1 per cent during the same period. However, when the 
same numbers of plants to the acre are grown in rows spaced 3.5 feet 
apart and in rows spaced 7 feet apart, the percentage of suckers de- 
veloped in the rows 3.5 feet apart is materially larger than in the 
rows 7 feet apart, in which there are twice as many plants to the 
row. The comparison is made quickly by dividing by 2 the first 
percentage in each pair given above. 
The average percentage of stalks headed is slightly higher in this 
case than when the method of spacing the rows 3.5 feet apart was 
used. The height of the plants also averages greater in most of the 
years when the rows are spaced 7 feet apart.

The reaction of the crop, as shown by yield of brush with this 
method of spacing, is quite similar to that in the case of the methods 
already discussed. Under favorable growing conditions the thicker 
rates give the highest yields, and in less favorable and poor seasons
