tile subject is obtained. These results are submitted in the hope that
they will be of inunediate use to farmers, who, in many cases, come
from the Eastern States, where the rainfall is abundant, and are
unfaiihar with conditions in this area.
It has been the plan in locating these experiment farms to obtain,
-is far as possible, representative conditions of both soil and climate,
il order that the results may be applicable to a large area.
The soil of the Bellefourche experiment farm is a very heavy clay
Called "Pierre clay" by the Bureau of Soils; to farmers and stock-
men it is familiarly known as "gumbo." It is chiefly characterized
by its stickiness when wet and by its imperviousness to water, espe-
cially after the surface becomes wet. It contains a fair amount of
hinus and appears to be rich in the essential elements of plant food.
From a practical farmer's standpoint, its chief disadvantages are
that it is very heavy and therefore expensive to work, and that it is
necessary to work it when it contains the proper amount of moisture.
From the behavior of the crops, this soil seems to be very retentive
of moisture and is productive when properly handled.
Table I shows the results of a mechanical analysis of Pierre clay.a
Its characteristic stickiness is perhaps explained by the large percent-
age of (.lay and silt, amounting to 35 and 43.2 per cent, respectively.

The Pierre e.lay passes gradually into a clay shale, which is found
at a depth varying from a few feet to several hundred feet. This
t*ype of soil is found extensively in South Dakota west of the Mis-
souri River, and in a few areas not covered with the glacial drift
east of the river. It also extends into Montana and Wyoming.
The field in which the greater part of the experimental work herein
reported has been conducted seems to be well adapted to the purpose.
Check pilts have bieen used in all plantings when practicable to do so,
an(d in most cases it has been found that there is little variation in
differentlyl parts of t he field.

    at Brookings. These were tested for several years, the best being
    grown in field tests. Some were grown as early as 1902 at Mellette,
    S. D)ak., andl in 1903 at the substation at lighlinore. Later, when
    (*ol"t)rtive work was begun at the substations at Edgeley and Dick-
    inson, N. Dak., the best varieties were sent there for trial. In 1908,
    when the work at the Bellefourche experiment farm was inaugurated,
    oIly those varieties which these various tests had shown to be best
    were uIsed.
    In t hlie progress of the work at various places many varieties have
    been discarded, so that those which are being grown at present may
    be regarded as the best of their chless.
    Tables II1, IV, and V show the average and annual yields of the
    duirum and(I common heats at the three experiment farms under
    discussion. In Table IV, which shows the yields at Ilighmore, two
    ('olulnis of averages are given, as most of the common wheats were
    not grown until two years after thie (duruni wheats were introduced.

    The highest average Yiehl of spring wheat at Beliefourlche is 23.2
    bushels per acre, as shown in Table III. This was obtained from two
    strains of the Kubanka variety, G. 1. No. 1440a (better known as
    S. P. I. No. 5639) and G. 1. No. 1516.6b Several other varieties have
    vielded nearly as much.
    ()f thile common wheats, Powers' Fife (G. 1. No. 3025) has yielded
    the most, 17.9 bushels per acre, or 5.3 bushels less than the Kubanka.
    Rysting's Fife ((G. I. No. 3022) is a close second. The Bearded Red
    Fife, which has yielded well at Highmore, has not been included( in
    these tests. Several strains of this valuable variety are being grown
    in the plant nursery. Some of these aire very promising and will be
    grown in comlparisoln with the other varieties as soon as sufficient seed
    is obtained.
    The Kubanka variety (G. I. No. 15316) has produced the highest
    average yield of thle duruini wheats at Iigihmiore, 22.4 bushels per acre
    for the seven-year period from 1903 to 1909, as shown in Table IV.
    The Ghirka Spring. the only conu1non spring wheat grown for the full
    period of seven years, gave an average yield of 14.5 bushels per acre.
    The Bearded Red Fife has produced the highest average yield of the
    coImmonn wheats fort lie live years from 1905 to 1909. Three varieties,
    Pedigreed Bluesteim, Minnesota No. 169, and Okanogan Valley Velvet
    Chairff, have each produtced an average yield of about 1.5 bushels below
    that of the Bearded Red Fife.
    The common and durum wheats have been grown on similar ground,
    with the exception of the 1909 crop. A comparison of yield of the
    two groups inll 1909 can not be made for that reason. The average
    yield of the Bearded Red Fife variety for the four years from 1905 to
    1908 is 19.5 bushels per acre, or 7.5 bushels less than the yield of the
    Kubanka for the same period(. The former, however, is at present,
    1910, discriminated against by the millers, although not to the same
    extent as is the (durum wheat. Its greater Yie ld, as compared with
    other varieties of common wheat, is for that reason partly offset
    by the lower price usually received for it. The Kubanka variety
    averages niearvly 9 bushels more than the Pedigreed Bluestem, the
    seconId connomn wheat in point of yield, an increase of more than
    4S per cent.

    1908 (Table III), a (Iry year, but in 1909, a season of abundant
    precipitation, it was slightly exceeded in yield by other varieties.
    At Ilighnore in 1904, the driest year during which tests have been
    conducted, three strains of the Kubanka, G. I. Nos. 1440, 1516, and
    1541, ranked in yield first, second, and third, respectively (Table
    IV). Likewise at Dickinson in 1909, with a rainfall considerably
    above the normal, the Kubanka was outyielded by other varieties,
    but in 1907, the driest year, it yielded the highest. While such
    com1parisons do not hold true for each year at each experiment farm,
    it appears that the Kubanka is better adapted than other varieties
    of durum wheat to dry climates and( dry seasons. It is very prob-
    able that for a period of years during which the precipitation
    approaches more nearly the normal than has been the case during
    the past few seasons, or when the precipitation is below normal,
    the superiority of the Kubanka variety will be more clearly shown.
    An important result of the variety tests is definite information
    concerning the comparative yields of durum and common spring
    wheat. It has been pointed out that the superiority in average
    yield of the best durum over the best common spring wheat has
    amounted to from 18 to 48 per cent of the vield of the common
    wheat, the smallest difference being at Dickinson. As previously
    noted, the average precipitation at each experiment farm for the
    period during which these comparisons are made is from 1 to 5
    inches above normal. This has undoubtedly resulted in a differ-
    ence less than would otherwise be the case, since it is only in dry
    years that the full value of the durum wheat becomes apparent. For
    example, at Ilighmore in 1906, with a seasonal precipitation of about
    1 inch above normal, the difference in yield between the Pedigreed
    Bluestem variety and the Kubanka was 12.2 bushels. The increase
    fromt growing the Kubanka in this case amounted to about 75 per
    cent. In 1904, with a precipitation of about 4 inches below normal,
    the difference -in yield in favor of the Kubanka amounted to nearly
    100 per cent of the vield of the Pedigreed Bluestem.
    At Dickinson the driest year since the variety tests were begun
    was 1907. The difference in vield that season between the Kubanka
    and the Ghirka Spring varieties was 9 bushels per acre, and between
    the Kubanka and the Bluestem 12.9 bushels, or a gain for the
    Kubanka in the hitter case of nearly 69 per cent. As the seasonal
    precipitation in 1907 was just about normal, it seems very probable

    The average of the two years' test at Bellefourche shows that the
    Turkey variety (G. I. No. 3055) produced the highest average yield,
    33.4 bushels per acre, having exceeded the next best, the Kharkof
    (G. 1. No. 1442), by 0.5 bushel per acre. It also has the highest
    weight per bushel and the highest percentage of winter survival.
    Results are not reported for either Ilighmore or Dickinson.
    In athlition to the varieties just discussed, which were grown on
    one-tenth acre plats, about thirty-five were grown in rows. These
    were obtained from various sections of the United States and Canada,
    and are the best varieties grown in their respective localities. Of
    these, the winter survival of all but ten was below 50 per cent. The
    winter survival of twenty-two varieties was less than 2 per cent.
    Only one variety, Turkey, survived to the extent of 90 per cent. No
    stronger proof should be needed that the farmer must exercise great
    care in the selection of varieties for his farm.
    At the Bellefourche experiment farm the winter wheat has yielded
    practically the same as the durum wheat when grown under the
    saMe conditions. In 1908 the average yield of the seven best varie-
    ties of winter wheat was 23.4 bushels per acre, whereas an average
    yiehl of 2:3.2 bushels was obtained from seven varieties of durum
    wheat grown on similar ground. The difference in yield between
    the best variety of each for the season is 0.6 of a bushel in favor of
    winter wheat.
    During the season of 1909 winter wheat on summer-fallowed
    ground produced from 31.5 to 44.5 bushels per acre according to the
    variety. A plat of the Kubanka durum wheat grown in the same
    fiehl, but in a different part#of the series and on lower ground,pro-
    duced 36.8 btushels per acre. An adjoining plat of the Turkey win-

    The best yielding oat varieties at Bellefourche are the Kherson
    and the Sixty-Day. They seem to be practically identical in both
    yield and appearance. The only difference noted is that the Kherson
    is one or two days later in maturing than the Sixty-Day and is
    slightly taller. The average yields are 36.4 and 36.3 bushels per
    acre, respectively. The Swedish Select ranks third, with a yield of
    33.3 bushels per acre. Other varieties range in yield from 18.5 to
    30 bushels per acre.
    Only Sixtv-Dav and Swedish Select oats have been grown at High-
    more for the full period of seven years. In 1906 the former was
    grown on sorghum ground, and therefore was not comparable with the
    other varieties. A plat of the Swedish Select on sorghum ground
    )v the side of the Sixty-Day yielded 42.8 bushels per acre, or 22
    bushels less than the plat of the same variety in the regular variety
    test. The average of the Swedish Select for seven years on ground
    comparable with the Sixty-Day is 41.5 bushels. The average yield
    of the Intter for t he same period is 40.2 bushels. A four-year average
    from 1906 to 1909, inclusive, of all varieties (Table VIII) shows the
    Kherso)n in the lead, with a vield of 41.5 bushels, and the Swedish
    Select a close secondl, with a yield of 41.3 bushels. Had the Sixty-
    Day been grown on comparable ground in 1906 it wouhl undoubtedly
    have equale(I either of these in yield.

    For t ihe three-year period the h ull-less barley produced only a little
    more thanii halt' as much as the best two-rowed variety, and for the
    two-year pIeriod less than half.
    At each experiment farm the two-rowed varieties of barley have
    given thile best yields. Thle lianna barley (G. I. No. 24) has given
    tie hIighest average yiel at Bellefourche and Ilighmore, but has
    not been grown at D)ickinson. The Hlanna, G. 1. No. 203, a strain
    very similar to Hanna, G. I. No. 24, has given the highest yield
    at the latter place. Thle ilaueien variety (G. I. No. 531), which
    lhas l)een grown at Iighmore for five years and at Dickinson for
    two years, has given the highest average yields for those periods.
    Tle principall disadvantage of the two-rowed varieties is that they
    do not conniand as ready a market as the six-rowed varieties. For
    feeding there is no appreciable difference between the two types.
    The varieties of two-rowed barley recommended for western
    North andi South D)akota are the Hannhen and the Hanna (G. I.
    Nos. 531 and 24). The Odessa and the Minnesota No. 6 are appar-
    enlitly thle best of the six-rowed varieties.
    At Dickinson rate-of-seediing tests have been conducted for
    three years with duruim wheat, two years with oats, and one year
    with common spring wheat. Tests with durum wheat, winter
    wheat, and oats were inaugurated at Bellefourche in 1909. The
    results at both experiment farms p)oinit to the conclusion that thick
    see(hing up to a certain point )rodtices a greater yield in favorable
    seasons, but in unfavorable seasons the thinner seeing does best.
    As much of thlie work has b)eeni done in favorable seasons the presen-
    tation o[ the results at this time would probably l)be misleading.
    An interesting point in connection with the test on winter wheat
    at Bellefourche is that seeding above 4 pecks per ac're has increased
    the percentage of winterkilling. The thicker seeding reduces the
    sul)lV1y of moisture available for each plant. During dry autumns
    the probable result is that the plants are weakened by the lack of
    m)ist ire and for that reason are more easily killed.
    It is reconiended that thin seeding be practiced. Not more
    than 5 pecks of durunm wheat. 4 pecks of common spring wheat,
    or 3 ()r 4 pecks of winter wheat soul be sown per acre. Barley and
    oats shloull not le sown thicker than 6 pecks per acre. Thinner
    seeding than this is often reconunmen led and is perhaps advisable
    in most hlocalities. While greater yields will be secured from thick

    -For the region herein discussed, western North and South
    < the following conclusions are drawn:
    !M-- (1) The success of the dry-land farmewill depend very la
    - upon the selection of varieties adapted to his conditions.
    LL O ----0
    o_ (2) Durum wheat is a more profitable crop than co on sp
    Sweat. The best variety is the Kubanka (G. I No. 1440 or
    (--- I No. 1516).
    (3) Winter N heat should be grown wherever it
    D winter. The best varieties are the Turkey (G. I. No. 305) and
    Kharkof (G. I. No. 1442).
    (4) Early or medium maturing varieties of oats, such as the St
    Day, the Kherson, and the Swedish Select, should be rown.
    (5) Two-rowed barleys yield better than the six-rowed v"e
    The best two-rowed barleys are the Ianna (G. I.
    and the Hiannehen (G. I. No. 531). The best six-rowed A
    the Odessa and the Minnesota No. 6.
