EARLY AND MID-SEASON POTATOS AT WISLEY, 1915. 



Report by the Trials Officer. 



One hundred and eleven stocks were sent for trial, and were planted, 

 together with fourteen other stocks obtained for comparison, on 

 April 9. There were in the trial one hundred and seven varieties, 

 viz. forty-five First-Early, thirty-two Second-Early, and thirty 

 Mid-season. They were planted in rows two feet six inches apart, 

 with eighteen inches between the sets in the row, on ground that 

 was deeply dug and moderately manured the previous autumn. 



The season was not altogether a good one for Potatos ; many 

 stocks were " cut " by the frost which occurred on the last day of 

 May, and the disease caused by Phytophthora infestans severely checked 

 many of the Mid-season varieties, but in spite of these drawbacks 

 and the dry spring the majority of the plants made excellent growth 

 and produced good crops, in most instances free from disease. The 

 cultivation was under the charge of Mr. J. Wilson, Foreman in 

 Vegetable Department. A Sub-Committee of the Fruit and Vegetable 

 Committee inspected the trial on July 29 and August 19, and 

 recommended that the following varieties, by reason of their heavy 

 crops and good appearance, should be cooked for inspection of their 

 quality by the full Committee, viz. : — 



Arduthie Seedling. Midlothian Early.
