GRAIN SORGHUMS IN THE TEXAS PANHANDLE.

SECOND SECTION, ROWS 7 FEET APART. 



The second section of these experiments differs from the first 

 section in the spacing of the rows, which are 7 feet apart, and of the 

 plants, which are twice as thick in the rows. 



Table XII shows the data recorded for Dwarf milo grown in rows 

 spaced 7 feet apart in the spacing experiments during the 6-year 

 period from 1914 to 1919, inclusive. Six plats were grown each 

 year, representing as many rates of seeding. However, the spacings 

 are not in all cases the same in all years.

 spaced 7 feet apart at the Amarillo Cereal Field Station during the 6-year period from 

 1914 to 1919, inclusive.

In 1914 the thickest rate averaged one plant to 3.7 inches and 

 the thinnest rate one plant to 8.6 inches of row space, with four 

 intermediate rates ranging from 3.9 to 5.7 inches of row space to 

 the plant. In 1915 the thick rate was one plant to 4.1 inches of 

 row space and the thin rate had a row space of 11.2 inches to the
