Bulletin No. 16 (for '88). 



"The Early Rose potato was the variety used. The 'seed' was obtained 

 from Ohio. Each plat received exactly the same treatment as to prepara- 

 tion and cultivation In all plats the potatoes were planted 14 inches 

 apart in rows 3 feet wide, except that in plat No. 6 they were put 24 inches 

 apart in the row. 



" The plats were 1-10 acre each in size. 



" Plat No. 1 was planted with the average run of potatoes as they came 

 from the barrel, cut to two eyes. 



"Plat No. 2 was planted with large, selected potatoes planted whole. 



" Plat No. 3, very small potatoes planted entire. 



" Plat No. 4, selected large potatoes, cut to two eyes. 



" Plat No. 5, small potatoes, cut in pieces containing two eyes each. 



" Plat No. 6, seed same as No. 1, potatoes planted in hills two feet apart. 



" The following table shows the yield calculated per acre:

"These results add to the evidence obtained heretofore at this station, and 

 to the many results obtained elsewhere, that by using whole potatoes of 

 large size for seed in place ot small potatoes or 'cut seed,' there folloics 

 an increased yield iyi crop. 



"But the results this year do not warrant the statement that if pays to 

 plant large whole potatoes. 



"The season and soil were unfavorable to such a test. When the sea- 

 son is favorable and the soil is rich, the evidence from many experiments 

 tends to show that the value of the increased yield produced by planting 

 large sized potatoes more than compensates for the increased outlay for 

 seed. 



" Experiments made at this station in a rich soil and m a fair season 

 in the year 1886, gave the following results per acre:
