COMPARISON OF ^■ARIETIES. 



BY O. S. GKONER '94. 



The object of this experiment was to test the comparative yields and the 

 per cent of marketable potatoes of forty-nine varieties, each variety 

 was planted on Jnne 1, 1892, in rows H3 inches apart each way, and 

 from 4 to 5 inches deep. The soil was a light sand. Two pieces were put in 

 each hill, each piece containing two eyes, making four eyes in a hill. The 

 potatoes were planted in plats one rod square, each plat containing thirty- 

 six hills. The following tables give the yield in pounds of each plat, the 

 percent of marketable potatoes and the computed yield per acre. A graph- 

 ical illustration of the com^Darative yield of the various varieties is also 

 given, on a scale of 60 pounds to the inch.
