The average results of the six tests conducted within the past three 

 years, however, have given us about 2 1-2 tons per acre more from 

 the sug-ar beets grown in rows 18 inches apart as compared with those 

 grown in rows 28 inches apart. Samples from the various parts of 

 this experiment were taken to the chemical laboratory and were an- 

 alyzed by Prof. Harcourt, in order to ascertain the percentage of sugar 

 from beets grown in rows at different distances apart. For the results 

 of these analyses, the reader is referred to the report of the Chemical 

 department, to be found in the Report of the College for 1904. 



Thinning Sugar Beets at Different Distances in the 

 Drills. For two years in succession, an experiment has been con- 

 ducted with sugar beets by thinning the plants to two, four, six, eight, 

 and ten inches apart in the rows. Each plot consisted of six rows, 

 fifty links (2 rods) in length, and eighteen inches apart. The experi- 

 ment was conducted in duplicate in each of the two years, the Klein- 

 wanzlebener variety being used throughout. The average results of 

 the four tests made in the two years are as follows : 



The results of this experiment seem to indicate that as the distance 

 between the sugar beets in the rows increases, the average size of the 

 individual roots also increases, but the yield of roots per acre decreases. 



Flat and Ridged Cultivation. Sugar beets have been grown 

 on the flat and on ridges in an experimental way in each of three years. 

 The experiment in each year was conducted in duplicate. Each plot 

 consisted of six row^s, each row being fifty links (2 rods) 

 in length. The Kleinwanzlebener variety was used throughout. 

 The average results for the six tests conducted in the three 

 years gave 18.82 tons per acre from the flat cultivation, 

 and 18.17 tons per acre from the ridged cultivation. These results, 

 therefore, show that for the three past years, about two-thirds of a ton 

 more of sugar beets per acre have been obtained from the flat as com- 

 pared with the ridged cultivation. 



Thinning Plants at > Different Stages. In each of the years 

 7903 and 1904, sugar beet plants were thinned when they were one-half 

 inch, two inches, five inches, and eight inches in height. The experi- 

 ment was conducted in duplicate each year, and the Kleinwan.zlebener 

 variety of sugar beets was used. The highest average yield per acre
