The barley on a series of these rows was root pruned just before 
heading, one row having the roots cut with a spade along one side, 
and another row along both sides, which we shall designate as half- 
root-pruned and root-pruned in the table which follows: 3

The influence of the excessive cultivation is thus seen to be detri- 
mental in some cases, and advantageous in others, if it is proper to in- 
terpret these, in general, small differences as having a meaning. If 
we take those with full records, we find the crop for five rows of the 
uncultivated to be 10.34 lbs., of the five corresponding rows half-root- 
pruned 10.75 lbs., and of the five corresponding rows root-pruned 
10.18 lbs., the differences being too slight to have meaning. Between 
the crops from the eight rows half-root-pruned and the eight rows 
root-pruned, the difference is 0.95 lbs,, scarcely sufficient to justify the 
conclusion that excess of root interference diminished the crop. 
The only conclusion to be drawn from this experiment is, that the 
experiment itself is inconclusive. . 
We may, however, infer that varieties differ in prolificacy, and that 
which variety we use for seeding is of consequence. 
FORAGE CROPS. 
Maize seems the established plant for forage purposes. The variety 
planted at the station was the Southern White, and the seed in gen- 
eral germinated well. The areas, one-twentieth of an acre; the fer-. 
tilizer used, four hundred pounds phosphate per acre, broadcast; the 
-planting four kernels to the foot. Planted May 30, vegetated June 7, 
harvested the last of September. D. seventeen, HE. eighteen and H.
