The average price is considerably lower than the average price for
a good quality of seed, because in these lots are included many which
are low in quality, both on account of adulteration and low vitality.

In the Baltic Provinces of Russia hairy vetch occurs as a more or
less persistent weed in grain fields, and practically all of the supply
of the seed from that region is secured by separation from the rye
In Prussia, especially in the provinces of East and West Prussia
and Pomerania, there is extensive production for seed, but in Ger-
many generally more hairy vetch is raised with rye for green fodder
than for seed. The rate of seeding used in Germany is considerably
heavier than that which has been found advisalble for seed purposes
in this country. The German Agricultural Society recommends
sowing 53 pounds of hairy vetch and 72 pounds of rye to the acre,
but the average rate of seeding is somewhat less, though the crop is
usually grown on light, sandy soil where a comparatively heavy
seeding is needed. Hairy vetch seed is universally sown with winter
rye and usually with the variety known as Johannesroggen, or
St. John's rye. This variety of rye is peculiar in that it can be sown
as early as June and at any time thereafter until the latter part of
September. It is a very free-stooling variety and makes a large leaf
growth close to the ground. This rye supplies excellent pasturage in
the fall, and the date of maturity is 10 to 15 day. later than common
As hairy vetch is usually sown in combination with rye it is not
necessary to separate the mixed seed as harvested when about one-
third of the mixture is vetch. Such mixed seed is far more economi-
cal to use than to pay the present high price for imported seed.
When a separation of the seeds is desirable it is easily and effect-
tively accomplished by the use of a spiral separator, known in Europe
as "Schneckentrieur," which requires no power, being operated by
gravity. This apparatus is covered by United States Letters Patent

nutritious. In growing such mixtures for seed, enough grain is used
to make about two-thirds of a stand and 20 pounds of the vetch seed
are added. Such a mixed crop is easily cut with a mower having a
swather attachment, or even with a binder. If more vetch is used
it is liable to lodge, especially in spots where the vetch is thick, and
the mowing is therefore rendered more difficult.
Where hairy vetch is planted alone, it nearly always becomes more
or less lodged, and should be mowed, if possible, against the direction
in which most of it is lying. After cutting the first swath, it should
be rolled upon the uncut vetch before cutting the second swath. The
two swaths should then be rolled out clear from the uncut vetch.
Sometimes three swaths are combined in this way. The cut vetch
should not be handled more than is necessary in curing, and care
should be taken in shocking to cover the pods as much as possible.
Hay caps are very desirable for this purpose. In thrashing pure
vetch it is sometimes desirable to have sharpened teeth on the con-
caves, as long vetch is inclined to wrap about the cylinder.
If hairy vetch is pastured rather late, the subsequent growth will
not be tall, but often is heavily set with pods. The same result can
be obtained by cutting the vetch early and feeding it green or putting
it into a silo. Such a second crop is much more easily mowed than
tall vetch, and in some instances excellent seed crops have been thus
Some farmers obtain their own supply of seed b)y cutting hairy vetch
for hay rather late, i. e., after some of the pods have ripened. Much
of this seed will rattle to the bottom of the mow, especially if a little
care is taken to shake each forkful as it is being used for feed. Such
late cutting reduces slightly the value of the hay, but the seed obtained
often jutifics the practice.
Hairy vetch ripens its pods over a period of two or three weeks.
The best crops are obtained when the first pods are fully ripe and the
upper pods well filled. The latter ripen in the shocks, and if carefully
handled comparatively few of the ripe pods shatter. It is best to cut
the crop early in the morning or on a cloudy day. In any event the
vetch, whether cut in bundles or otherwise, should be put into shocks
at once and left thus till thrashed. The most important rule is to
handle the cut crop rapidly and as little as possible.
An incidental advanthige to the use of locally grown hairy vetch
seed is its much better germinating quality. Old seed has a large
percentage of hard seeds, which lie in the ground a long time without
sprouting and which are practically valueless to the farmer. Fresh
samples collected in Europe in 1911 gave a uniformly high germina-
tion, only one testing below 91.5 per cent. Imported seed, which is
usually 1 year old, frequently shows a hard-seed content of 10 to 40
per cent.

While hairy vetch for hay or green manure has long been grown
successfully in nearly all parts of the United States and Canada, ,.L
there has been relatively little investigation made of its seed produc- '
tion. Table II is a compilation of published American data in -
seed pruduction, together with unpublished results obtained by the 4
Department and its cooperators. i
These results show yields ranging from 3 to 15 bushels per acre,
with an average of 61 bushels for all the trials. Such a yield makes
a d<,id(edly profitable crop. Were vetch is grown alone the seed
yields are heavier, but this is largely counterbalanced by the diffi- ,
culty of harvesting, so that it is advisable as a rule to grow it in :
combination with rye.
