INFLUENCE OF MANUKE UPON SUGAR 



BEETS* 



W. H. JORDAN AND G. W. CHURCHILL,. 



SUMMARY. 



(1) Tlipse experiments were undertaken to test the accuracy 

 of the statement that sugar beets are of an inferior quality when 

 grown on land to which stable manure is applied in the spring. 



(2) The experiments have been conducted during four consecu- 

 tive years, mostly on the Station farm. Comparisons have been 

 made of the quality of beets not manured, those grown with 

 commercial fertilizer, mostly 1,000 lbs per acre, and those grown 

 on land receiving in the spring, before planting the beets, from 

 40,000 lbs. to 80,000 lbs. stable manure per acre. Beets from at 

 least six varieties of seed were grown during the four years. 



(.3) The results are almost unanimous in one direction. The 

 beets have been of high quality with all three methods of treat- 

 ment, averaging somewhat better with the farm manure than 

 with no manure or with commercial fertilizers. 



INTRODUCTION. 



The value of a given lot of sugar beets for sugar-maldng pur- 

 poses depends chiefly upon two factors, viz.: the percentage of 

 saccharose in the beets and the percentage and character of 

 the solub\e compounds accomijanying the sugar. In general a 

 beet is valuable in proportion to its content of crystallizable 

 sugar, but if this is attended by too large an amount of certain 

 soluble non-sugars, the effect is to prevent the crystallization of 

 some of the saccharose which under better conditions would be 

 secured in the manufactured product.
