to be absolutely injurious, while comparing the results from applications made this 

 year (1899), plots 21-24, we find a gradual increase in yield as more lime was applied, 

 coupled with a corresponding decrease in the percentage of sugar and the coefficient of 

 purity. 



Again, comparing plots nine to fourteen with fifteen to twenty, where treatment 

 was the same, with the exception of an addition of lime, we find generally a falling off 

 in the yield, which is also accompanied by decrease in the percentage of sugar and 

 eo-efficient of puritj'. 



TEST OF VARIETIES. 



Variety tests have been conducted during the past two years, using each year the- 

 varieties of seed that have been at hand. 



Below is a table giving yields per acre each year, and results of analyses of the same:

It should be noted that the above are yields of perfectly clean beets, carefully 

 trimmed for factory purposes, and that the soil on which they were grown is not such 

 as we would select for growing beets were we raising them for commercial purposes. 

 The yields for the two years seem to compare well, relatively, with the yields of beets 

 on the farms of the State. 



From the tests of sugar beets made throughout the State with seed furnished by the 

 Department of Agriculture and sent out from this office, the following tables of averages 

 have been arranged: 



Reports from 2.57 farmers who tested Kleinwanzlebener, gave the average percentage 

 of sugar 16.42, and purity 83.3. From 47 farmers testing Vilmorin Improved beets,, 

 average 16.50 per cent sugar and 84.4 purity. 



EXPEBIMENTS ON DIFFERENT KINDS OF SOIL. 



The table below is a summary of the experiments made by farmers throughout the 

 State and gives the average analyses from five difTerent kinds of soil, as classified by the 

 men performing the experiments. The average yield in 1899 is also given:
