An average yield of 25 tons per acre is thought to be a good crop. 



Three methods of extracting sugar from beets are discussed, and sug- 

 gestions made and quoted as to the practical methods of beet growing 

 and sugar making. 



Chemical analyses of sugar-beets, D. O'Brine, D. Sc. (pp. 

 7-12). — The experiments with sugar-beets at the station, begun in 1888 

 and reported in Bulletin No. 7 (See Experiment Station liecord, Vol. I, 

 p. 13), were continued in 1889. '' In 18S9 it was proposed to grow beets 

 on ])oor (unfertilized) soil and on rich (fertilized) soil, and to note the 

 difference, if any, in the substances present in the ash, to compare the 

 specific gravity of the expressed juice and the per cent of sugar pres- 

 ent." An early frost i>revented proposed investigations of the relation 

 of the sugar content in the beet to the weight of tops and of the feed- 

 ing value of tops. Five specimens of beets were analyzed, two of 

 Silesian, two of Imperial (one of each grown in rich and one in poor 

 soil) and one of Vilmorin. The results are stated in tables. The per 

 cent of the sugar in the juice was in one case larger and in the other 

 smaller in the beet grown in rich soil than in the beet grown in poor soil, 

 and the same was true of the water. The per cent of sugar was de- 

 termined in sections of specimens of the Silesian and Imperial beets, 

 and the results are given in a table, which includes data for the percent, 

 ages of grape, cane, and total sugar. The sections were made across 

 the beet, 1 inch apart, from the top down. 



The percentage of sugar increased steadily, except in a single case, 

 from the top to the lowest section. Determinations of the water and 

 nutritive ingredients, and analyses of the ash in the five specimens were 

 made. In general it was found that the percentage of ash was greater 

 in the beets grown on the rich soil, and that the percentages of iron, 

 alnminum, calcium, and phosphoric acid in the ash were greater in the 

 beets from the poor soil. The specific gravity of the expressed juice of 

 the beet was not a correct index to the per cent of sugar present in the 

 specimens. There was a somewhat regular increase in sugar content 

 from the top of the beet downward. The average per cent of sugar 

 present in the experimental crop of 1889 (9,98 per cent) was but little 

 less than in that of 1888 (10.45 per cent), but the greater yield of beets 

 per acre in 1889 more than compensated for the smaller per cent of 

 sugar.
