July 29, plats 21, 23, 25 and 27 cultivated. 



Augusts, all plais cultivated. 



The tillage continued until the vines so covered the space 

 between the rows that the cultivator could no longer be used with- 

 out injuring the foliage. 



The following table shows the results obtained from the differ- 

 ent plats. 



CULTURE EXPERIMENTS — POTATOES- 



The average from plats given thirteen cultivations was 337.5 

 bushels per acre. The average for nine cultivations was 367.5. 

 As has been mentioned, this year was especially favorable for po- 

 tatoes and the average for the state was extra high, being 122 

 bushels per acre. 



In 1S96, the experiment was continued. The adjoining plats 

 selected were a part of the series which had been planted to corn in 

 1894 and 1895. After the corn was harvested, all plats were drilled 

 to wheat as a cover crop. This wheat made fair growth and when 

 plowed under in the spring added s ")me humus to the soil. Other 

 than this no fertilizer or manure was used, and two crops of corn 

 had already been removed since a light application of barn 

 manure was made. That the results might be of more value, it 

 was decided to give to some of the plats only ordinary tillage, to 

 other plats extra good tillage and to others excessive tillage. 



The record of the preparation of the soil for the potato crop of 

 i8g6 is as follows : The plowing was done as early in the spring
