1 In this plat the rows were alternately 40 and 80 inches apart. Thus, each row was adjacent to an 
60-inch space on one side and a 40-inch space on the other.

the foreground had been thinned to a 12-inch row space per plant.

The yields shown in Table 22 indicate a slight advantage in the 
40-inch over the 80-inch row space for both forage and grain. The 
average yield of forage from the 40-inch rows was also larger than 
that from the rows alternately 40 and 80 inches apart; the grain 
yield, however, was largest on the alternate 40 and 80 inch rows. 
The average vields per acre for the four years and the four rates of 
the 40, 40 and 80, and 80-inch rows were 37.9, 38.5, and 36.6 bushels
