EXPERIMENTAL FARMS 



7 GEORGE V, A. 1917 



POTATOES— TEST OF VARIETIES. 



On the dry land, twenty-five varieties were planted May 20 on summer-fallow. 

 Barnyard manure was applied in 1914 before the land was ploughed for the fallow. 

 The rows were 30 inches apart and the sets were placed 12 to 14 inches apart in the 

 row... They were dug October 18. 



The same varieties were planted on the irrigated part of the farm on land broken 

 snd backset from brome grass sod in 1914. No irrigation was applied. They were 

 planted in the same manner on May 13, and dug October 16. The yield was com- 

 puted in each case from one-hundredth of an acre plot. Spraying was necessary on 

 three occasions to subdue the ravages of the Colorado beetle which appeared in great 

 numbers.

In the table it will be noted that the Gold Coin was rather low. This is rather 

 unusual and hard to explain for during the last eight years, of all the varieties tested, 

 it has averaged high (this includes the results of 1915) heading the list on the dry 

 land and almost at the top on the irrigated land. We therefore recommend from the 

 8 years' tests the following varieties for main croppers : — Gold Coin, Morgan Seedling, 

 Wee MacGregor, Table Talk, and Empire State, but personally prefer the first-named. 

 Careful observations were taken by digging a few hills each week during the season of 

 each variety to gather data regarding the earliness of the different sorts under test. 

 Out of the 25 varieties tested the following stand out for earliness: — Irish Cobbler, 

 Vick Extra Early, Rochester Rose, and Reeves Rose.
