produced from rows with plains 12 inches apart in the row. the 
9-inch spacing ranking second, with an average of 25.8 bushels to 
the acre. The lowest average yield was obtained from the thickest 
rate. For dwarf milo in rows 88 inches apart the best distance 
between plants appears to be from 9 to 12 inches.

COMPARATIVE YIELDS i'ROM 44-INCH AXD >S-IXCH ROWS. 
Table 27 shows the annual and average acre yields of Dwarf Yellow 
milo in the spacing experiments, arranged so that direct comparisons 
may be made readily between the rows spaced 44 inches and 88 inches 
apart, containing approximately the same number of plants to the 
acre. The spacings are arranged in five groups, each showing the 
yields from one set of rows spaced 44 inches and one spaced 88 
inches apart, the space between plants in the row in the latter being 
half that in the former. The data given are the distances between 
rows in inches, the approximate row space between plants, and the 
annual and average acre yields for each spacing.
