almost entirely overcome by the character of the season, as

THE EELATIOX OF THE TIME OF PLANTING TO THE PROTEIN 

 CONTENT OF WHEAT KERNELS 



On account of certain differences in the physical appearance 

 of kernels from early and late planted wheats in preceding 

 seasons, experiments were conducted in 190S to ascertain more 

 detinitely the relation of early and late planting to the protein 

 content of wheat kernels. In these experiments it was intended 

 to conduct parallel series of plantings at the University Farm, 

 Davis, and at the substation at Tulare. At the former place, 

 however, conditions were not favorable for early seeding, and 

 all had to be planted too late to be at all satisfactory in pre- 

 senting any decided contrast in planting time, particularly for 

 the winter wheats, there being but fifteen days between the early 

 and late seeding. The first plantings of the season were not 

 made until February 27. and the second plantings on ]March 

 13. At Tulare there was a wider difference, the plantings 

 having been made on December 12, and January 17. 



As a matter of record, however, the analyses of these grains 

 are presented below:
