TRIAL OF POTATOS FROM VARIOUS LOCALITIES. 



A trial of the influence of climate and soil on the crop-yielding value 

 of seed potatos was carried out during 1908 at Wisley. Seed was obtained 

 from gentlemen in different districts, whose names are given in the 

 following list, who were able to certify the locality in which it was grown. 

 Each of these kindly sent 20 tubers of the variety 'Up to Date.' 

 These were all planted on April 9th on good sandy loam that had 

 previously been moderately manured. When mature the crop was lifted 

 and weighed, the Irish seed and one of the Scotch giving the heaviest 

 yield. The average of the whole of the stocks was 84 lb. from 20 tubers, 

 that from Wisley (grown for one year) being rather above the average, 

 viz. 86 lb. Practically all the produce was of good size for use, very few 

 small tubers being produced.
