GRAIN SORGHUMS IN THE TEXAS PANHANDLE. 



25 



stands usually produced the higher yields in the favorable seasons 

 and the thinner ones in the less favorable years. The highest yield 

 in the different years was not produced by the same stand each year. 

 It is necessary to study the averages to determine the rate which will 

 give the best results during a series of years.

Table XI shows the annual and average acre yields of Dwarf milo 

 in rows spaced 3| feet apart in the spacing experiments during the 

 6-year period from 1914 to 1919, inclusive. In this table the plant 

 spacings which were approximately the same are combined. The 

 first or thickest rate represents a space per plant ranging from 6 to 

 8 inches; the second has a space of 9 to 10 inches to the plant, and 

 the third has 12 inches of row space to the plant. In the fourth rate 

 the row space ranges from 15 to 18 inches, and in the fifth, from 20 

 to 24 inches. All rates were not obtained throughout the entire
