suits for three years were a difference of from 1,067 to 

 1,828 kilograms of grain per hectare in favor of the large 

 seed. But the difference was in general greater the first 

 year than later. The use of large seed gave a crop with 

 kernels larger than those grown from small seed. 



Middleton (6) reporting experiments with wheat, oats, 

 and beans, says the large seed yielded almost twice as much 

 as small seed, in the case of wheat; the difference was less 

 marked with oats and with beans there was scarcely any. 



Bolley (7), of north Dakota!^, after experiments lasting 

 for four years in which plump kernels of large size and plump 

 kernels of small size were selected for seed, concludes from 

 the results that "perfect grains of large size and greatest 

 weight produce "better plants than perfect grains of smell 

 size and light weight, even when the grains come from the 

 same head". 



After presenting data of fourteen years' experiments 

 with large, mediuiu and small seeds of oats, barley, field 

 peas, spring and winter wheat, mangels, sugar beets, swedes, 

 fall turnips, field carrots, rape, and potatoes C. A. Zavitz(9) 

 of the Ontario Agricultural College concludes that "it 

 seems very evident that large seeds will give a greater 

 yield than will an equal number of small seeds, in the case 

 of at least twelve different classes of farm crops."
