POTATOES. 



The results in the experiments with potatoes this year were rather disappointing 

 in comparison with those of last year, for in some instances there seemed to be a con- 

 tradiction in results. The variety tests of eleven leading varieties planted on summer- 

 fallow gave the following yields per acre for each of the past three years. The yieW 

 is based upon two rows each 78 feet long.

Dreer's Standard 



Morgan Seedling 



Rawlings Kidney (Ashleaf Kidney) 



Everett 



Money Maker 



Rochester Rose 



Late Puritan 



Reeves' Rose 



Dalmeny Beauty 



Vick's Extra Early 



Irish Cobbler 



Irish Cobbler is of good quality and in a short season is of decidedly superior 

 quality to any of the other varieties, but is of so low yield and so irregular in shape 

 that it can scarcely be recommended as a commercially profitable variety to grow. 

 Moneymaker produces larger potatoes than any other variety. They are white, long, 

 and have medium eyes, but are of poor quality. Dreer's Standard, Morgan Seeding, 

 and Rawlings Kidney (Ashleaf Kidney) are of good shape and fair quality. 



An experiment has been conducted for the past two years on depth of seeding 

 with the following results: —

Two plots of potatoes othervv'ise alike in every respect were cultivated differently 

 in 1912 and 191?>. One plot was hilled in June whereas the other was kept level. The 

 potatoes from the plot treated to level cultivation were slightly more sunburned 

 than those froin the plot that was hilled. If digging is not done early there is more 

 danger from a few of the potatoes in the level plot being frozen by the early fall frosts.
