BROOM-CORN EXPERIMENTS AT WOODWARD, OKLAHOMA. 89 
row'space at the same rate of seeding as they do in the first section. 
The reaction of the crop under these two methods is quite similar 
in many ways. While the number of suckers produced increased as 
the stands decreased, the total percentage of suckers developed under 
this method is approximately one-third less than developed when the 
other method of spacing the plants was used. This should tend 
naturally to increase the percentage of headed stalks, but it is not 
in proportion to the decrease in the production of suckers. The in- 
crease in headed stalks amounts to 5 per cent only, and the decrease 
in suckers amounts to 35 per cent. 
In yield, quality, and length of brush, the reaction of the crop to 
this method of spacing the hills and plants is quite similar to that 
of the first method discussed. The response of the crop at the differ- 
ent rates varies with seasonal conditions. The thicker stands usually 
outyield the other rates in favorable seasons, and the thinner stands 
give the best results in dry years. At the intermediate rates fair to 
good yields of good-quality brush are produced in all seasons.
