test, concludes that perfect grains of large size and high 

 weight produce better plants than those of smaller size 

 and weight even though the grains come from the same spike. 



The Burdue University Experiment Station submits a 

 summary of results taken from a number of stations thus: (36) 



Yields in bu. per acre

Minnesota 

 Nebraska 

 Kansas 

 Ontario 



Averages 30.7 26.6 4.1

Ontario 46.9 40.4 6.5 



Tennessee 28.6 23.4 5.2 



Averages 30.6 27.0 3.6 



The figures from experiments by Burnett at the Iowa (37) 

 Station tend to show that with oats the heavy seed and the 

 light seed were about equal pound for pound but not seed 

 for seed, nor measure for measure. All plots were sown at 

 the rate of three bushels per acre. 



The Minnesota Station (38) state that a plump heavy 

 kernel of grain will produce a stronger plant and nourish 

 it better than will a shrunken, light $ernel. They quote 



from the Nebraska station the following table: 



Yield per acre in bushels 



Kind of seed 1900 1901 2 yr. av. 



Heavy 29.5 29.3 29.4 



Light 23.0 26.7 24.8 



Gain in favor of heavy seed 4.6 



A similar experiment in their own station gave an in- 

 crease of 9-fc bushels per acre in favor of the heavy seed and 

 heavy wheat gave a yield of 36 per cent greater than that 

 of light wheat.
