IMPROVING THE QUALITY OF WHEAT. 



Table 13. — Crops grown from light and from heavy seed for four years — Continued. 



CROP. 



Comparing the analyses of the hght and heavy seed in this table 

 with those in the preceding tables, it will be noticed that the tot'al 

 and proteid nitrogen are both uniformly higher in the light seed. 

 The nonproteid nitrogen is not so uniform as in the previous analyses, 

 but the general tendency is the same. 



In the crop the high total and proteid nitrogen of the light seed is 

 uniformly transmitted. There is no uniformity in the nonproteid 

 nitrogen. As was to be expected, the heaA^y seed produced in the 

 first two years the largest yields per acre. The quality of light or 

 heavy weight as indicated in the resulting crop by weight of grain 

 per bushel gave some indication of being transmitted. In 1900 

 there was an absence of data on the subject, but in 1901 the heavy 

 seed in each case produced grain having a greater weight per bushel 

 than did the light seed. 



Turning to the column showing the absolute amount of proteid 

 nitrogen produced per acre, it is very apparent that the heavy seed 

 produced in 1900 considerably larger amounts of proteid nitrogen 

 per acre than did the light seed, but in 1901 the difference was very 

 slightly in favor of the light whea't, which advantage continued 

 with the light wheat during the remaining years.
