12 EXPERIMENTS WITH POTATOES 



72. White Star. — This old variety stood well in the test, 

 giving a yield of 306 bushels per acre. The tubers were long, 

 evenly cylindrical, and of a clean, white appearance. Vines 

 rather slender and long, of late growth ; four per cent, scabby. 



73. White Mountain. — Healthy, vigorous grower; strongly 

 resistant to early blight. Well-proportioned, large potatoes ; 

 twelve per cent, scabby, and these among the smaller tubers. 

 Yield good. 



74. White Rose. — The tubers were long and cylindrical, with 

 very light pink, shallow eyes. A medium, second early potato, 

 of the White Star type ; yield heavy, but too many small tubers. 

 The largest were not large. 



79. White Ohio (Vick, 1896). — This is a seedling of the 

 Early Ohio, only white in color. The introducers claim it to be 

 the earliest white potato grown. It did not prove superior with 

 us, although its general appearance was good. The yield was 

 an average one, tubers flat and oblong in shape, and containing 

 a fair proportion of small ones. Shallow eyes. 



80. Governor Rusk. — A potato of nice appearance, smooth, 

 long and cylindrical in shape, of reddish color, and very pro- 

 ductive. The tubers averaged good size ; the vines were strong 

 and large; eighteen per cent, scabby. A desirable variety if it 

 continues to do as well as this season. Ripens with the second 

 early varieties. 



2. MURIATE VS. SULPHATE OF POTASH. 



It has been thought in recent years that although muriate of 

 potash is the cheaper form of the potash salts, for the amount 

 of fertilizer it contains, it nevertheless has some properties that 

 render it undesirable for a number of vegetables, among them, 

 potatoes. Experiments in Germany and at the Massachusetts 

 Station, point very conclusively to this fact. We tested these 

 two forms of potash on each of the eighty varieties of potatoes 

 grown the past season, one half of each row being treated with 

 sulphate, and one half with muriate.* The other forms of fer- 

 tilizer used, as phosphoric acid and nitrogen, were the same 

 throughout. The results were as follows : 



Of the eighty varieties, forty-seven gave a heavier yield with
