(b) The percentage of stigar remained the same with 500 Ibs., 
1,000 lbs. and 1,500 lbs. of fertilizer, which was 1 per cent less 
than when beets were grown without fertilizer. 
(c) The coefficient of purity was slightly decreased by the use of 
commercial fertilizers. 
(d) The size of beets was increased. 
(e) The use of 500 lbs. of fertilizer-was attended with profit of 
nearly five dollars an acre, but the profit decreased when more was 
used. When 1,500 lbs. and more were used, there was an actual 
loss. 
(f) The cost of growing one acre of sugar beets at Fayetteville 
was $28.20, not including cost of seed, fertilizer and marketing. 
(2) The effect of stable manure upon yield and quality of beets 
_ was shown in the following ways: * 
(a) The yield was increased in every case, the average increase 
being 8,720 lbs. an acre. 
(b) The percentage of sugar was increased an average of 1.5 
per cent. ae 
(c) The coefficient of purity was increased an average of 1.6. 
(d) The size of beets was decreased an average of 2 3-4 ounces. 
(e) The use of 20 tons of stable manure per acre furnishes very 
much more plant food than do 500 lbs. of the commercial fertilizer 
used, but it is not all available at once. 
(3) In growing beets at different distances apart in the rows, the 
nearer the beets were in the row the smaller they grew in size, and 
the smaller yield they gave per acre. 
I. COOPERATIVE EXPERIMENTS IN GROWING SUGAR 
BEETS. 
INTRODUCTION. 
In 1897 this Station undertook no experiments in the growing 
of sugar beets except those carried out on the Station farm. 
Some analyses of miscellaneous samples grown by various farmers 
in different parts of the State were made and published in Bulletin
