EXPERIMENT STATION RECORD. 



Culture experiments with potatoes, A. Kindell {Mustiala Ar/L 

 College Ept. lt<'J2, PI). 18-20). — The exi)eriinents include culture trials 

 with 15 different varieties of potatoes, with determinations of the yields 

 and starch contents of the different varieties, and the yield of starch 

 per hectare in each case. The potatoes grown contained from 12.3 to 

 2().;> per cent starch, the average being 14.01 percent. — F. w. woll. 



Potatoes [Ontario Agl. Col. and Exptl. Farm Rpf. 1893, pp. 225-230). 

 licport and discussion of a cooi)erative test of jiotatoes undertaken 

 by several members of the Ontario Agricultural and Experimental 

 Union. The selection of perfect, average sized potatoes is advised, 

 and storing in pits during the winter. Rural Ko. 2 gave the highest 

 j'ields, followed by Empire State. Kaiser, a new variety, is recom- 

 mended. The results are detailed in 2 tables. 



Experiments with potatoes and root crops in Belgium, P. db 

 Cali-we {Expo.se Gt(U. E.ipn\ Jard. OawK ls92-"J3, pp. 3<i-42, 45, 46, 

 59, 60, 63-73). — These experiments consisted of variety, fertilizer, and 

 culture experiments on potatoes; fertilizer experimeuts on chicory 

 and parsnip ; effect of treating potatoes with Bordeaux mixture ; 

 and variety tests of beets and turnips. When potatoes were cut 

 into sections and the cut surface placed downward, the crop was 

 in two instances larger and in two instances smaller than when the 

 cut surface was uppermost. On chicory in a dry year there was but 

 little difference in the crop whether organic, nitric, or ammoniacal 

 nitrogen was used. On parsnips nitric nitrogen gave the best results. 

 Potash was more effective on parsnips than on chicory.
