FIG. XXIII Method of Gracing Strength of Straw. 



As will be seen from the above the main notes are taken in the field. Laboratory 

 The laboratory work consists chiefly in interpreting field trials by comparing work. 

 yields and examining the product for quality. This work, together with the 

 prosecution of scientific investigations intended to further elucidate problems 

 in breeding, and the preparing of reports and other publications, requires the 

 entire winter. 



The analysis for quality of grain includes in the main the following 

 points : 



1. Weight per 1,000 kernels. 



2. Weight per hectolitre (2.85 bushels) / 



3. Percent hull or scale.
