1920.] 1919 Potato Trials in East Sussex. 211 



The experiments, which are being continued, suggest promising 

 possibilities. The data at hand indicate that well-dried barley, 

 wheat, rye and oats of good quality are able to withstand 

 protracted exposures to dry heat at comparatively high 

 temperatures. They also show that seed infections from 

 bacterial blight of barley and oats may both be eliminated by 

 exposing the infected seed to dry heat at temperatures that 

 leave the seed still viable. Finally, it is demonstrated that 

 stripe disease of barley, and Helniinthosporimn blotch of oats, 

 as well as loose smut of barley and smut of oats, are markedly 

 reduced without materially injuring the germination of the 

 seed. 



A REPORT of the potato trials carried out last year by the 

 East Sussex Count}- Council has recently been received by the

Cropping tests were carried out at live centres, with the 

 results given below.

It will be noted that King George yielded 7 tons 15 cwt. 

 per acre more than did Templar, and that Arran Chief 

 (Scotch seed) gave a yield of 5 tons 3 cwt. per acre more than 

 the locally-grown seed of the same variety. 



At Albouvne. — Similar results were obtained, except that 

 Great Scot gave a slightly better return than Lochar. 



At Pett. — ^The plots here were about one-tenth of an acre 

 in area. A subsidiary test was made as to the value of spraying, 

 but owing to the abnormally dry season the advantage obtained
