tion Plots 1920 cultivation are receiving prominent atten- 

 tion. The important part now played by 

 potato crops on both farms and allotments makes it very 

 desirable that such trials should be conducted widely through- 

 out the country. 



For several years past, the Ministry's Potato Trials at 

 Ormskirk have been supplemented by trials in different parts 

 of the country, in order to compare the cropping quahties 

 of the more important immune varieties, and to ascertain, 

 also, the varieties most suitable to particular soils and districts. 

 The results, which should be of very great use to potato growers, 

 have clearly demonstrated the value of such trials, and point 

 to the need for the work to be continued in subsequent years 

 in every county, and on the many classes of soils within each 

 county. It is hoped that as a result of this year's trials more 

 precise information on these points may be available. 



It was reahsed that the most valuable results could only be 

 obtained by working all the plots uniformly. A memorandum 

 was therefore circulated by the Ministry to all Horticultural 

 Sub-Committees and to County Agricultural Organisers, setting 

 out definitely the fines on which the trials should be conducted. 

 The Ministry's Scheme provided for {a) farm trials, and (/)) 

 allotment trials. The trials themselves were divided into two 

 main sections. The object of the first section was to demonstrate 

 the cropping powers of the well-known immune varieties, 

 and of the second to compare the earliness of cropping qualities 

 of certain early varieties. In the ]\Iinistrv's memorandum
