GRAIN SORGHUMS IN THE TEXAS PANHANDLE. 
19 
suckers was produced on each plat, amounting to over 66 per cent in 
the early and to more than 45 per cent in each of the other seedings. 
In the unfavorable season of 1918 few suckers were produced. These 
amounted to about 14.5 per cent in the early and late seedings and 
13 per cent in the normal seeding. 
The percentage of stalks bearing heads runs high in the favorable 
seasons and low in the unfavorable ones. In the season of 1915 the 
early seeding produced 97 per cent of headed stalks, the normal 
seeding 94.8 per cent, and the late seeding 91.4 per cent. The 
maximum of 100 per cent was made by each seeding in 1919. In 
the poor seasons of 1916 and 1918 the percentage of headed stalks 
was quite small.

The average height of the plants ranged from 2.3 feet in 1918 to 
4.8 feet in the late seeding in 1915. Growing conditions in the vege- 
tative period largely govern the height of the plants. With favorable 
conditions during this period the height will be greater than with 
unfavorable conditions when followed by favorable conditions during 
the fruiting period. Dawn kafir usually attains a height of about 
4 feet under average conditions. 
The yields vary with seasonal conditions. The highest total yield^ 
10,220 pounds, was made by the late seeding in the favorable season 
of 1915, and the lowest, 1,500 pounds, by the normal seeding in the 
poor season of 1918. Low yields were obtained in 1916. That year 
the early seeding produced 1,660 pounds of crop; but only 11.9 per
