GRAIN SORGHUMS IN THE TEXAS PANHANDLE.

stands resulted from unfavorable conditions at seeding time, which 

 affected germination. In some cases poor germination was due to 

 wet, cold soil, and in others to dry soil. The plants have a tendency 

 to adjust themselves to environing conditions, and where the stands 

 were thin a larger number of suckers were produced than in the 

 thicker stands. This condition reduced materially the differences 

 in row space per stalk between the thick and the thin stands. 



In most of the years the early date required longer vegetative and 

 total growing periods than either the normal or late dates. This was

due largely to the cold condition of the soil, which prevented normal 

 growth the first few weeks after seeding. The longest time required 

 for the crop to mature was 132 days by the early date in 1918, and the 

 shortest was 82 days by the late date in 1919. 



The suckers produced vary with the stands, date of seeding, and 

 seasonal conditions. The thin stands have a higher percentage of 

 suckers than the thick ones in the same season, but the percentage 

 varies with the season. In 1918 but few suckers were produced in 

 any date of seeding. They ranged from 13.2 per cent in the late date 

 to 21.5 per cent in the normal, the early date having 18.6 per cent.
