II farmer on the dry plains has
well that will furnish just enough
water for fifty head of stock, it would
be absurd for him to try to keep sixty
or seventy-five head on the same sup
rly of water and 1t is equally ridicu-
lous for him to attempt to crowd the
plants in soil where the moisture is
limited
Some plants may develop with less
moisture than others. but alfalfa is not
one of these plants on the other hand
1t is conceded by all western farmers
that an abundance of moisture is the
key to success in growing alfalfa for
hay.
When 1t is well established, alfalfa
will endure long droughts and still re-
vive when water is applied; to that
extent, 1t is adapted to dry farming
and its deep-rooting tendency may en-.

In 1908, an alfalfa nursery plat with
ont irrigation for eleven previous
months, produced at the rate OF two
and three-fifths tons per acre the first
cutting; and then made second
growth equally as good. that was left
for seed. The plat had been seeded in
1907 to Turkestan alfalfa and thinned

year. The growth In 1908 was made

conserved in the soil, but such phe-
nomenal yields can hardly be expected
without irrigation. In the favored
spots, before mentioned. alfalfa can

The growing OF alfalfa seed offers
great opportunities to the farmer on
dry lands. because the fact has been
well demonstrated that alfalfa Yields
seed best when the plant makes a slow
dwarfed growth. when 1t really lacks
for moisture. but has enough to set
and fill the seed.
Seed grown under dry conditions has
duced with an excess of moisture, and
1t is usually free from dodder and
other noxious weeds II the field has
had any culture care. There is de-
mand for dry land alfalfa seed that far
exceeds the supply.

A thin. uniform stand is absolutely
necessary, even to thinning. as in beet
culture; but the stand can usually be
regulated by the amount of seed sown.
II has been found that plants twenty
inches apart will support each other
and not lodge or lay on the ground as

the crop. A four.row drill adapted to
sowing alfalfa seed is needed to com

beet drill. with the addition OF an ai-

be modified to suit the work.
The seed should be sown shallow.
