thinning of beets can be extended over a period of two weeks with¬ 
out injury to the crop. 
10. Variety tests. Six varieties, Zehringen; Yilmorin’s Im¬ 
proved, grown in Russia; Ivleinwanzlebener, grown by Vilmorin ; 
Pitschke’s Elite ; Vilmorin’s French, very rich ; and Schreiber’s Elite 
were grown side by side with Ivleinwanzlebener, strain not given, 
with almost identical results in percentage of sugar and purity, the 
sugar ranging from 15 to 17.20 per cent., and the purity from 76 to 
81.9. The average of all the samples analyzed in this test is 16.04 
per cent, sugar, and 78.9 purity. 
11. Number of irrigations. At Rockyford, beets were grown 
without irrigation, with one, and with four irrigations. This experi¬ 
ment was of little value, being defeated by the unusually heavy 
rains of that season. 
At Pueblo, Mr. C. K. McHarg applied water to one-half of some 
experimental plots twice after the 20th of August, the other half re¬ 
ceiving none after that date. The two later irrigations produced an 
increase of one-seventh in the. weight of the crop, and the percent¬ 
age of sugar was increased; beets from the half irrigated late, con¬ 
tained 16.42 per cent, sugar, 81.0 purity, and those from the other 
half contained 15.79 per cent, sugar, 81.7 purity. 
12 . American grown seed vs. imported seed. Two samples of 
American grown seed were used, one grown in Utah and the other 
in New Mexico, both were strains of Klein wan zlebener beets. The 
imported seeds were the Original Kleinwanzlebener, Vilmorin, 
Mangold, and Elite Kleinwanzlebener. 
The Elite Kleinwanzlebener and the Vilmorin were sent us by 
the U. S. Department of Agriculture as the best beet seed that they 
could get. The Original Kleinwanzlebener was selected by the U^ah 
Sugar Company as, in their judgment, the best brand of seed on the 
market from which to raise their own seed. The Utah grown seed 
produced as large a crop and one richer in sugar and purity than 
the average of these three. It excels its parent strain in richness 
and purity, and is but little inferior in quality of crop. 
The New Mexico seed equals the Vilmorin and is not far be¬ 
hind the original Kleinwanzlebener. 
The germinating quality of the seed is quite satisfactory. 
In 1899 the questions whose solution were attempted were: 
Does it pay to subsoil ? The results of ten tests made at this 
Station show an average gain of 18 per cent, in the weight of the 
crop as the result of subsoiling. 
Is it advisable to plant the beet seed very early ? The average
