274 STORRS AGRICULTURAL EXPERIMENT STATION. 
DESCRIPTION OF SAMPLES. 
ANALYSES OF DISTINCT SPECIES OF GRASSES GROWN WITH 
DIFFERENT QUANTITIES OF FERTILIZERS. 
In the year 1892 the Station began a series of experiments 
on the effect of nitrogenous and of mineral fertilizers on pure 
species of grasses, which were grown upon small plots (one- 
eightieth acre each) in the grass garden. ‘The grasses were 
grown in drills and were kept as free as possible from admix- 
tures of weeds or of other grasses. The experiment was con- 
tinued for three years. In 1894 it was noticed that many of 
the plots, especially those having mineral fertilizers only, pro- 
duced a large proportion of clover, making it difficult to sample 
the grasses and have the samples pure. Sorrel and other small 
weeds were also filling up the drills, and it was thought best to 
remove the grasses and to cultivate and re-seed. This was 
done in August, 1894. In the spring of 1895 it was noticed 
that some of the plots were not well stocked. ‘The vacant 
places were filled out, either by transplanting or by sowing 
more seed, and the experiment was discontinued for that year, 
except that the same kinds and quantities of fertilizers were 
used, but no samples were taken for analysis. 
In the spring of 1896 the drills of grasses were found to be 
well stocked, and the experiment was renewed. /The samples 
of timothy, orchard grass, and meadow fescue described below. 
represent the fifth annual crop grown on plots which had the 
same kinds and amounts of fertilizers each year, while the 
brome grass and red-top represent the second annual crop. 
GREEN FODDER. 
1649, 1654, 1659, 1664 Timothy (Phleum pratense ).—Grown in the Station 
grass garden in 1896. The samples were taken July 14, at which time the seed 
was beginning to form and the stems were fairly succulent. No. 1649 was from 
a plot without fertilizer. The growth was light, thin, and of a pale color. No. 
1654 was from a plot to which was applied dissolved bone-black at the rate of 
320 pounds an acre, and muriate of potash at the rate of 160 pounds. Growth 
very similar to that on 1649. No. 1659 was froma plot which had dissolved 
bone-black and muriate of potash the same as 1654, and in addition nitrate of 
soda at the rate of 160 pounds per acre. The growth was heavy and of fair 
color. No, 1664 was from a plot which had dissolved bone-black and muriate 
of potash the same as 1654, and in addition nitrate of soda at the rate of 480 
pounds per acre. There was a much larger crop than on the other plots, with 
thick bottom and heavy leaf growth.
