GRAIN SORGHUMS IN THE TEXAS PANHANDLE. 23 



late seeding comes second with 20.8 bushels, and the normal seeding 

 takes last place with 18.3 bushels. The averages show that early 

 seeding for Dawn kafir is best and that late seeding is better than 

 the normal date. 



Manchu kaoliang produced the best yield in one year from the 

 early seeding, in one year from the normal, and in four years from 

 the late seeding. The late seeding ranks first with an average of 

 20.1 bushels, the early seeding is second with 16.1 bushels, and the 

 normal seeding is third with an average of only 14.3 bushels. This 

 indicates that Manchu kaoliang should be seeded late if grown at all 

 in this locality, which is true also of feterita. 



SPACING EXPERIMENTS. 



The spacing experiments were conducted with Dwarf milo (C. I. 

 No. 332) and Dawn kafir (C. I. No. 340). The object of these experi- 

 ments was to determine the reaction of these crops to the different 

 environing conditions and to determine the distances between plants 

 and rows that would give the best yields. These experiments were 

 divided into two sections. The first section consisted of six plats 

 each year during the 6-year period from 1914 to 1919, inclusive. 

 The rows in these plats were 3^ feet apart (fig. 10), the plants being 

 spaced at different distances, representing six rates of seeding each 

 year. The second section also contained six plats each year. It 

 differs from the first section in the spacing of the rows, which are 7 

 feet a art (fig. 11), and of the plants, which are twice as thick in 

 the row as in the first section, thus representing the same number 

 of plants per acre. 



DWARF MILO. 



FIRST SECTION, ROWS Z\ FEET APART. 



The agronomic data recorded on Dwarf milo in the first section of 

 the spacing experiments are presented in Table X. This table shows 

 that in 1914 the thickest stand was one plant to 3.7 inches of row 

 space, and that the thinnest stand was one plant to 17.4 inches of 

 row space, with the other four rates ranging from 4.3 to 11.7 inches 

 of row space to the plant. In 1915 the row space to the plant ranged 

 from 6 to 21.4 inches. In 1916 the thickest rate was one plant to 

 4.2 inches of row space and the thinnest rate was one plant to 20.8 

 inches. In 1917 the first five rates were practically identical with 

 those of 1915, ranging from 6 inches of row space in the first or thick 

 rate to 18 inches of row space to the plant in the fifth rate. The 

 thin rate had a row. space of 24 inches to the plant. In 1918 the row 

 space ranged from 3 inches in the thick rate to 9.1 inches in the fourth 

 rate and 12 and 12.8 inches in the fifth and sixth rates, respectively. 

 In 1919 the germination was poor, making it impracticable to get the
