Sugar Beets.

The results given are uniform in showing that small beets, such 
as weigh from one to three ounces, are richer than large ones, thirty 
to forty ounces in weight, by two per cent, or more. , nil®*; 
The conclusion of this bulletin indicates that the author had 
the general question of the adaptability^ of Colorado to the produc¬ 
tion of sugar beets in view rather than any cultural problem, for he 
says, “ We believe that it has been established that the soil and climate of 
Colorado are favorable to the production of sugar beets , and that they can 
be successfully and profitably raised to the advantage , both of the farmer 
and manufacturer .” 
Mr. Frank Watrous, in charge of the substation at Rocky ford’ 
grew T beets in 1890, ’91, and ’92, and records the results of his ex¬ 
periments in bulletin No. 21. The season of 1890 was spent in 
groping after facts, and the product, though encouraging, was not 
large. The yield obtained ranged from eight to seventeen tons per 
acre. Some of these yields were from half acre plots, others esti¬ 
mated from single rows. 
In 1891 an experiment in irrigating beets was made, from 
which Mr. Watrous concludes that, in an ordinary season, one irri¬ 
gation during the growing season is sufficient to produce the best 
results both as to tonnage per acre and saccharine matter contained. 
Four plots of one-fourth acre each were planted to Vilmorin beets. 
Plot 1 was not irrigated; plot 2 was irrigated once; plot 3 was irri¬ 
gated twice; and plot 4 was irrigated three times. The dates Yf 
irrigation are not given. The results are: 
Plot 1. Yield: 9 tons per acre. Sugar: 14.25 per cent. 
Purity: 80.5 per cent. 
Plot 2. Yield : 10.8 tons per acre. Sugar : 15.2 per cent. 
Purity : 84.3 per cent. 
Plot 3. Yield : 9.9 tons per acre. Sugar : 14.22 per cent. 
Purity: 79.5 per cent. 
Plot 4. Yield: 9.9 tons per acre. Sugar: 13.0 per cent. 
Purity: 76.0 per cent. 
In 1892 the plots were 1-100 and \ acre each, four of the six¬ 
teen plots being J acre in area. The yields from the \ acre plots 
were 18.7 tons, 20.5 tons, 25.0 tons, and 25.7 tons per acre, and the 
sugar percentage 15.18, 16.7, 15.9, and 18.9. The coefficient of 
purity was between 82 and 85. The yield from the 1-100 acre plots 
was somewhat higher, as was to be expected, the sugar content 
ranging from 13 to 15.8 per cent., and the coefficient of purity from 
76 to 85. 
The plan of culture adopted as the result of the three years’ 
study is as follows: After land had been plowed, harrowed, and 
made quite smooth, even, and free from lumps, stones, or trash, seed
