1913] Shaic: Studies on Infiucnces Affecting Protein Content of Wheat 89 



To further secure data upon the effect of the time of planting 

 upon the quality of the grain, twelve (12) varieties of wheat 

 were seeded at Ceres on four different dates, in rows I6I/2 feet 

 long and 12 inches apart, as follows: 



First planting November 28, 1908 



Second planting December 12, 1908 



Third planting December 31, 1908 



Fourth planting January 19, 1909 



The grain made a good stand and grew well during the season 

 and matured as shown in the following table : 



Date of Ripening 



This series of plantings is of special interest in that out of 

 the twelve varieties planted all but one show the highest protein 

 content in the latest planting, and the one exception shows the 

 highest in the third planting. In this case the difference between 

 the protein content of the third and fourth plantings is less than 

 one-half of 1 per cent. It is further of interest to note that 

 there was quite a regular increase in the protein content in the 

 order of planting. While the season was evidently one con- 

 ducive to the development of a relatively high quality of grain
