same as on soil poor in uitrogpu, and It is tlierefore coucludecl that tlie effect 

 of this substance on the yields can not be attributed to its rendering the nitro- 

 gen of the soil more available. 



In the experiments with sugar beets 500 kg. each of superphosphate, nitrate 

 of soda, and kainit were applied per hectare, and the sulphate of manganese 

 was applied in quantities of 10 and 50 kg. per hectare. The use of the man- 

 ganese compound slightly lowered the yield of beets, but their sugar content 

 was apparently raised in the same proportion, so that the yield of sugar on 

 all plats was the same. 



The chemical composition of beet seed, with special reference to the com.- 

 position of the seed of several fodder beet varieties, O. P^allada (Mitt. Clicm.

 The composition of beet seed as determined by different inxestigators is dis- 

 cussed and reported, together with the results obtained by the author. The re- 

 sults of analyses of the seed bolls of different varieties of beets are given in 

 the following table :

The ash of the seed bolls of the Mammuth variety was found to contain 20.o(> 

 lier cent of potash, 11.98 per cent of lime, and S.21 per cent of phosphoric acid: 

 the ash of Oberndorf 10.72 per cent of potash, 0.S7 per cent of lime, and 12 per 

 cent of phosphoric acid : and the ash of Eckendorf 18.59 per cent of potash, 

 9.30 per cent of lime, and 12.31 per cent of phosphoric acid. Analyses of the 

 seed proper showed an average content of 21.82 per cent of potash, 4.06 per cent 

 of lime, and 40.05 per cent of phosphoric acid. 



The chemical composition of sug'ar-beet seed, F, Strohmer and O. B"'allada 

 (Ostcn: ViKjitr. Ztsclir. Zuclccrindits. u. Luiidir., UWli, .Yo. 1, p. 12; abs. in 

 Zentbl. Agr. Chem., 36 (1907), No. 5, pp. 52.M26).— The results presented show 

 the following composition of sugar-beet seed : Nuclein 3.16 per cent, protein 

 17.25 jier cent, amids 5.76 per cent, glycerids 17.82 per cent, phytostearin 0.96 

 Iier cent, lecithin (».4(> i)er cent, starch 19.5S i)er cent, pentosans 3.0.'i per cent, 

 other nitrogen-free extract substances 24.70 i)er cent, crude liber 1.90 per cent, 

 oxalic acid 0.39 per cent, and ash 4.99 per cent. The ash includes 2.70 per cent 

 of i)hosi»horic acid, 3.09 per cent of potash, and 0.23 per cent of lime. 



The results secured on the experiment fields of the Russian society of 

 sugar manufacturers, S. L. Frankfort {Abs. in Zhur. Opuitn. Agron. [Rtiss. 

 Jour. Expt. Landic], 7, (1906), Ao. 6", pp. 696-698). — It was observed that the 

 average variation in the results was reduced in proportion to the fertility of 

 the soil. 



In 1905 better results were secured from the application of the fertilizer in 

 the rows together with the seed than by broadcasting. During two seasons the 

 seed and fertilizer were mixed in definite proportions and sown together in 

 drills. The yield of beets was about the same as when the ai)plication of fer- 

 tilizer in the row was made in the usual way, hut the growth of the young 

 plants was not so vigorous.
