quantity of vegetation to be incorporated with the soil. 
The roots are well supplied with tubercles. It will produce 
from 6 to io bushels of seed per acre, which is relished by 
poultry or hogs, and about two tons of hay. 
The New Era variety will mature seed in about one 
month less time than the Whipporwill and may meet a 
demand for late sowing in orchards. It does not grow 
nearly so rank as the Whipporwill. 
This plant should be sown in drills from 22 to 32 inches 
apart. ' The work may be done by a grain or beet drill. 
One or two early cultivations should be given, after which 
it will cover the ground. This plant can be sown as late as 
the first of July where intended only for fertilizing purposes. 
It is a splendid plant to sow in orchards to relieve the trees 
from the reflection of the sun in late summer, winter and 
early spring, after which it may be plowed under as a 
fertilizer. 
Two plats, one-tenth acre each, that produced Cow peas 
in 1900, were devoted to the growth of beets in 1901. The 
peas were cut with a mower so that only the roots and 
stubble remained to plow under. Two plats of the same 
size that had never been fertilized, and which had grown 
crops similar to those on which the Cow peas were sown, 
were planted to beets also for comparison. Both plats 
were given the same treatment. The plats on which the 
Cow peas had been grown yielded 16 tons per acre, the 
other plats yielded 12.5 tons per acre. That the nitrogen 
supply was augmented by the growth of the peas was 
apparent from the color and vigor of the beet tops. 
the field pea. {Pisiim arveuse.) 
The Field pea does fairly well at Rocky Ford if sown 
very early in spring, so that its growth may be made before 
the approach of hot weather. 
The seed should be sown the latter part of March. 
The peas will ripen the first week in July. 
The yield on the Station grounds in iqoi was 23bushels 
from two acres. The yield in 1899 was at the rate of 16 
bushels of seed per acre. In addition to the yield of grain 
there was produced at least 3 tons of splendid feed on the 
two acres. The above returns are only medium, for in 
neither case were, the conditions such as to give the best 
returns 
The variety grown in 1899 was the “Mummy;’ that 
grown in 1901 was the “Marrowfat.” I consider either of 
them preferable to the Canada pea for this section.
