FACTORS OF INCREASE HI 



seeds were placed correspondingly closer to- 

 gether, or in other words, if the seeds were 

 planted according to weight instead of num- 

 ber, the results might be reversed. For it is 

 evident that the same weight or measure of 

 seed will contain a much larger number in 

 case of small seeds than of large, and in plant- 

 ing the small seeds will require less ground 

 area for development, and consequently a 

 greater number of plants can mature upon an 

 equal space. 



This phase of the question has been tested 

 by Lehmann. He planted 188 grams each of 

 large, medium and small peas upon equal 

 sized plats of ground, and although there 

 were more than twice as man3^ small seeds as 

 large, and nearly once and a half as many 

 medium seeds as large, still the harvest was 

 greatly in favor of the larger seeds, both per 

 area and per plant. (Data in table vi., page 

 118). 



A practical lesson is very pointedly brought 

 out here, that in sowing farm seeds the 

 amount of the harvest depends quite as much, 

 and it may be more, upon the quality (size) 

 of the individual seeds as upon the weight or 

 measure sown per acre. 



Is it not apparent that large seeds show Superiority of 

 great superiority over small seeds in numer- large seeds
