GRAIN SORGHUMS IN THE TEXAS PANHANDLE.

which includes two good seasons and one poor one, there is practically 
no difference in the average yields from the first, fourth, and fifth 
rates. In the 4-year period, which includes two rates only, the 
average yield is in favor of the 15 to 19 inch spacing. This same rate 
leads in the first 5-year period, but is exceeded by the 11 to 13 inch 
spacing in the second 5-year period. In the 6-year average, which 
includes only two rates, the 15 to 19 inch spacing again has first- 
place. These results indicate that under such conditions a stand 
with about 15 inches of row space to the plant is probably the safest 
rate.
