The influence of self-fertilization on the degeneration of the sugar beet, 

 K. Andrlik, V. Barto.s, and J. Urban {Ztschr. Ziickeriitdus. Bohmen, 3S (1909), 

 No. 7, pp. Jf09-Jil8). — The results of the experiments here reported indicated 

 that the degenerative influence of self-fertilization varies with different indi- 

 viduals and manifests itself in a reduced sugar content and a prevalence of red 

 and yellow roots. Other indications of degeneration were changes in the shape 

 of the crown and of the root and the appearance of green crown beets. 



A comparison of nitrate of soda, nitrate of lime, and nitrogen lime as fer- 

 tilizers for sugar beets, .J. T'rcan (Ztsehr. Ziiekerindiis. Jiiihiiieii. .33 (1909). 

 No. 9, pp. 535-5-'i7). — The results of 2 years' experiments indicate that nitrogen 

 lime is a satisfactory fertilizer for sugar beets, especially when the rainfall is 

 sufficient, but this efficiency is not equal to that of nitrate of soda. The 

 efficiency of nitrogen lime in 1906, when 403 mm. of rain fell during i\.c vege- 

 tative period, was S5.G per cent as compared with nitrate of soda, but in 1907, 

 when only 349.(5 mm. of rain fell during the growing period, the efficiency was 

 only 75 per cent. The sugar content of the beets fertilized with nitrogen lime 

 in 1900 was 0.3.5 per cent higher than that of the beets which had received 

 nitrate of soda, while in 1907 it was O.IS per cent lower. 



The fertilizing effect of lime niti'ate in 1907 was greater by 11.3 per cent than 

 that of nitrate of soda, and the sugar content of these beets was on an average 

 0.16 per cent higher. The results of these experiments also show that nitrogen 

 fertilization on soil not largely lacking in nitrogen may reduce the sugar con- 

 tent of the beets, while, on the other hand, if the soil is poor in nitrogen it may 

 increase the sugar content. 



The possibility of substituting nitrate of lime for nitrate of soda in sugar- 

 beet culture, J. Stoklasa (Ztsehr. Landw. Versuehstc. Osterr., 12 (1909), No. 8, 

 pp. 627-636). — The report of experiments conducted shows that the best yield 

 of sugar beets was secured where nitrate of soda was used as a fertilizer. The 

 beets grown with nitrate of soda were also richer in sugar than those grown 

 with uiti'ate of lime. The outcome "of the experiments is regarded in general as 

 a decisive proof that nitrate of lime can not be substituted for nitrate of soda 

 as a ferilizer for the sugar beet.
