yield. The potash increased the vigor of the vine and delayed the ripening of the 

 crop. At Farnham, where the fertilizer tests are in the fourth year and the soil is 

 deficient in carbonate of lime, a marked beneficial effect on the yield of hops was 

 obtained from the annual application of 1 ton of lime per acre. 



Analyses of barley, J. Mahon (Queensland Dept. Agr. Rpt. 1903-4, p- ?5). 

 Analyses of 5 samples of barley are reported, of winch 2 were grown in Queensland. 

 According to the author, the analyses show that the local-grown barleys compare 

 favorably with Hungarian and English specimens, containing a little more starch 

 and a little less proteid matter. In these respects they were said to be superior to 

 California barley. 



Variety tests with beets, von Seelhorst (Deut. Landw. Presse, 31 (1904), Nos. 

 }:, pp. 421, 422; 48, pp. 428-430; 49, p. 435). — The yields of a number of varieties of 

 fodder beets grown from 1898-1903, inclusive, are reported. The White Eckendorf 

 variety led in yield of beets. It was found that in general a high yield of beets was 

 accompanied by a low leaf production and a low yield of beets by a high leaf pro- 

 duction. The varieties which produced small yields of beets and high yields of 

 leaves were richest in sugar. The highest percentage of sugar was shown by the 

 Red Leutewitz variety. The dry matter and the sugar content of the different 

 varieties show a marked degree of correlation so that within certain limits the one 

 can be estimated from the other. 



Six varieties of sugar beets were grown for 6 successive years, including 1903. 

 Breustedt led in the average yield of beets with 38,250 kg. per hectare. In the aver- 

 age sugar production per hectare, Schreiber Imperial stood first with 6,303.4 kg. 

 The extreme difference in the average yield of sugar per hectare between the 

 varieties was 493.8 kg. The coefficient of purity which ranked from 84.02 to 86.34 

 was lowest in the varieties which led in yield of beets and sugar content and highest 

 in the varieties rich in sugar but low in the yield of beets. The quantity of leaves 

 produced seem more dependent upon the season than upon the variety. A com- 

 parison of the results for the 3 years shows that the sugar beets produced from 6,828 

 kg. to 7,405 kg. of sugar per hectare and the fodder beets from 6,715 to 7,092 kg. 



Variety tests of fodder beets, F. Wohltmann et al. (Tllus. Landw. Ztg., 24 (1904), 

 No. 86, pp. 989, 990). — The yields of 33 of the principal German, English, and French 

 varieties of fodder beets are reported and the experiments briefly described. The 

 cylindrical-shaped varieties yielded the largest quantities of beets, the smallest quan- 

 tity of leaves, and stood lowest in sugar content, while the varieties approximating 

 the shape of the sugar beet gave the lowest yield of beets, a very high yield of 

 leaves, and ranked first in sugar content. 



The tankard varieties stood close to the cylindrical-shaped sorts in yield and com- 

 position, and the globe varieties produced very large yields of leaves and a medium 

 quantity of beets of good quality. The long and horn-shaped sorts produced a rela- 

 tively small yield of leaves and a medium yield of beets, with a sugar content rang- 

 ing from satisfactory to high. The color of the beet showed no connection with its 

 richness in sugar. 



Experiments with nitrate of soda as a fertilizer for fodder beets, T. Remv 

 ( Deut. Landw. Presse, 31 (1904), Xos. 58, pp. 507-509; 59, pp. 513-515). — The results 

 of 38 inoperative experiments are reported. All plats received a general application 

 of barnyard manure, 1,100 kg. of kainit or a corresponding quantity of 40 per cent 

 potasli salt, 350 kg. of Thomas slag applied with the potash fertilizer, and 200 kg. of 

 superphosphate per hectare, applied immediately before planting. In addition to 

 this treatment some plats received 300 kg. of nitrate of soda at the time of planting, 

 and others 300 kg. at the time of planting and an additional 300 kg. in June. The 

 varieties grown were Cimbal Giant ami Eckendorf Original. 



The average results for all tests of both varieties show an increase in yield of 98.7 

 per cent on the plats receiving 300 kg. of nitrate of soda, and of 90.8 per cent on
