 these fertilizers were applied with barnyard manure they all gave a profit, the 

 largest £4 2s. 7d. per acre over the unnianured plat being secured from ground 

 Florida phosphate.

 C. VON EcKENBRECiiEK (Ztuchr. Siiifit iisiiul U.S.. 191)9. Sup., PI). 3-.')6 ; ahs. in Dent. 

 Landic. I'rcsse, 36 {1909), Ao.s. 15, pp. 159. 160; 16, p. i77/).— Cooperative tests 

 wei'e conducted in 1008 in 27 different localities of Germany with 20 varieties 

 of potatoes, and the results secured in each individual test are reported in 

 tabular form and described. 



According to starch content the leading varieties were Agraria, Erste von 

 Nassenheide, and Prof. Wohltmann, with 21.5, 21.,3, and 21 per cent of starch, 

 respectively. The leading varieties in productiveness and their yields were as 

 follows: Hassia. 27.040 kg.: Alma. 2.5,010 kg.: and Fiirstenkrone. 24,910 kg. per 

 hectai'e. Arranged according to starch production, Prof. Wohltmann stood first 

 with ;i yield of 5,180 kg.. Bohms Erfolg second with 5.000 kg., and Switez third 

 with 4,920 kg. per hectare. 



Notes on the composition, disease resistance, keeping quality, and value for 

 different uses of the varieties are given, and all results are tabulated in detail. 

 Bojar, Switez, Brocken. Bohun, Bohms Erfolg, Erste von Nassenheide, and Prof. 

 Wohltmann showed the highest keeping quality, and Alma. Bojar, Bohms Erfolg, 

 Richter Imperator. and Brocken are considered the best varieties for eating 

 purposes.

 of potatoes were grown and yielded on an average 28,640 kg. of tubers per 

 hectare (about 25.500 lbs. per acre), containing 17.90 per cent of starch and 

 producing an absolute average yield per hectare of 5.126 kg. (4.502 lbs. per 

 acre).
