SAN ANTOINIO EXPERIMENT FARM.


There seemnis good reason for believing that a substantial and
)profitable a-riculture may be developed in this section if thle best
lmethlods of tillage and rotation are used, tg.tcf.r with the crops
best suited to the local renditions.

THE CLIMATE OF SAN ANTONIO, TEX.

The average annual rainfall calcutilated from the records of tlhe
Weather Bureau, !',iiii,,. with the year 1S7S, is 2S.1 inches, which
is about the same as at Lincoln, Nebr., or St. Paul, Minn., but
because of tlie irregularity of its occurrence thlie compact character
of tlie soil, which causes a large loss in surface run-off, and the higher
evaporat ion of thlie region the effectiveness of tlie rainfall is lessened,
imiking thlie coiuntrv semiarid rather than semihliumid, as at Lincoln
and St. Paul.
Tie suminers are hot and with a rather dry atmosphere, which
results in raplid evaporation of moisture from the soil surface and
from thlie leaves of plants. The winters are in the main mihld and
pleasant, but the rather frequent occurrence of thlie northerss"
(during this season often results in hard freezes.
Table I gives thlie al)solute mininumi temperatures and the dates
of the first and last killing frosts for each year since 1892. The
lowest temperature recorded in this period was 4 F. in February,
l1S99, and killing frosts have been known to occur as hlate as April,
although in the majority of cases the last one was in tlie month of
February. The sudden changes to low temperature often cause great
injury to fruit trees which have been started into growli duhiring the
wairmn, pleasant days of winter. For these reasons it is unsafe to
grow fruit trees except those hardy enough to withlstand a moderate
d(../,. .of freezin or those that will remain dormant throriiliit the
warmest days of winter or early spring.

Table IV gives the rainfall for each month in the year for eighteen
years, beginning with 1891. It will be noted that the monthly rain-

fall from April to September, inclusive, averages over 2 inches and
that in the renlaining months from October to March it averages less

than 2 inches. If the rainfall each month would regularly approach

the mean rainfall for that month, as given in the table, there would

be no reason why fair crops should not be raised every year, but the

rainfall during the year is so unevenly distributed that the yield of

crops for each season is exceedingly variable.

Previous to May, 1901, there were five months and previous to

April, 1902, there were six months of drought. The year 1893 was

a year of low precipitation, but the distribution was of such a nature

as to be favorable to Sprin't crops.

SOIL CONDITIONS OF THE REGION.

S,1an Antonio lies in the southern extension of what is known is the
"Black Prairie lezion," or t lie Pll;k I .andls" o"l' exas, aiInd ne;ir lie('
northern edg of an area known geologicallyI as lie '" iR (Mranihe
Plain." The soil is mostly tlie result of tlie wea tlin, i' of lile-stone
rocks of tlie paperr ('relaceous period. There have heen recent
alluvial deplosits washed down froin tlie hidl i lands nort'Iwest of the
city, resulting in hoVal mAMlilications.i hiely through I lie addition of
coarsler ilat'erial. The typial soil is a heavY black or brownisli clay

containn 22.S per cent of calcium carbonate in tile surface foot, while
the adjoining black soil contained only 7 per cent. Other analyses
ga*\e different degrees of variation between these extremes.
Table VI presents tlhe results of mechanical analyses of three soil
types oni the Sanil Antonio Experinment Farmn. The "light spot" on
lield B 5, where tlie first sample was taken, is one of the typical light-
colored spots just mentioned. Thle sample of dark soil is rel)resenta-
tive of the common black waxy soil of thle section and was the soil
that surrounded tle light spot. This sample wvas taken but a few
rods fr mii the first one. By referring to the table it will be noted
that thlie light spot contains a very mluich higher p'.rii(tt;ige of lime,.
both in thle first and second foot, than the dark soil, and it also con-
tains less organic matter. Analyses made by l)r. L. J. Bli.,,'_ of the
surface foot of these two borings showed percentages of 01 :;iiii matter
as follows: Light soil, 1.42 per cent; dark soil. 2.76 per cent.
Thlie samples of soil taken from field AB 8, near the south end of
the farm, showed only a trace of lime in the surface foot. While the
mechanical analysis shows about thlie same proportions of sand and
clay in this sample as in the samples from field B 5, for some reason
this soil is much more easily tilled and tools scour in it with greater
ease. Locally, it is known as "sandy" '' soil, in distinction from the
black gumbo, although the analysis sllOws little difference. Experi-
menlts have not vet been made to ascertain the relative productiveness
of tillhis type of soil as compared with thlie soil that is richer in lime.
This diversity in thlie lime content and of organic matter is probably
associated within thle irregular growth so often noticed in fields of sor-
ghium, corn, and horticultural and other crops.

(Irain crops ihave not beell comml*onl ruLsed other than for forage
purposes in thlie region about San Antonio. Wheat, oats, barley, and
rye do not ordinarily yield well. This failure to set seed see1is to be
due chiefly to tlie prevalence of fu ngous diseases and insects. Rust
appears early in the spring before tlie grains have headed out and
weakens ltheni very material v. WYork is being continued with a
ImiIrber of varieties of cerenls for hlie purpose of stil(dVinig these rusts
iinitl other diseases.
()On Noveimber S, 1907, there wVere planted on thle experiment farit
ili one-fiftli-acre plants three varieties of wheat, four varieties of oats,
ail a variety of rye. The rate of seeding for wheat was ,ill pounds
an1id for oaits 55 )pounds per acre. Rlust attacked the wheat about
(lie inid(lle of M.arch and so sapped thlie vigor of the crop that very
lw yields resulted, as shown by tle aieea below:

SAN ANTONIO EXPERIMENT FARM.


EXPERIMENTS WITH FORAGE CROPS.

Sorghmin is one of the surest and( most remunerative forage crops
in the vicinity of San Antonio. It is highly drought resistant, and
when planted in rows and cultivated will make a fair crop of hay even
in the driest seasons.
When sorghumin is planted thickly in drilled rows and kept well
c(ultivate(d during the summer very much better forage yields are
obtained than when sown b)r)a(dcast, especially during tlie drier sea-
sIns. The sorghum hay that hlias been produced from cultivated
rows is somewhat coarser thlianm when b)roadlcasted, but the greater
Yields obtained from row plantiir.,, particularly in dry seasons, more
than coml)ensate for tlie slightly decreased market value.
iSumac and Red Amber so(rghums proved to be the best yiehlding
varieties tried. Although thlie Sumac variety gave but two cuttings
a i Red Amber three cutt ings, thlie former variety producedd the greater
(liuanltity of forage per acre. For three successive years Sumac has
been thle best yielding variety on the exl)eriment farm. Its stalk is
coarser than that of the Amber sorghum, but is very sweet and juicy.
In tlhe rotation plats lthe Sumac variety yielded 13 tons to the acre
and Red Amber 7 t f)nr, from three cutll i-.
Table IX slows tlie forage yields of two plantings of sorghum
vw. ie ties. It will be noted that the yield was considerably reduced(
byv late planting.

.Mlillet grows well in seasons having at least an average amount of
rainfall and should prove to be a very useful crop in the farm rota-
tio ns. Those varieties that mature in from forty to fifty days
might follow thle winter oat crop when the May and June rainfall
permits, thus securing two hay crops from thlie field in one season.
After thlie corn crop is removed in July advantage iii- dil occasionally

numl)er of cases the nuts were not properly filled out. Peanuts are
not likely to prove profitable, at least on the heavy black type of
soil.
MEXICAN SEEDLING PEACHES.
In February, 1905, at the su,-nre-tion of Mr. William A. Taiylr,
there were sent to the farm about 500 seedling peach trees that had
been grown by Mr. G. L. Tabor, of the Glen Saint Mary nurseries in
Florida, from seeds collected by Mr. G. Onderdonk, of N uzr.,rv, Tex.,
in the (lrv-land fruit regions of Mexico. As Mr. Onderdonk himself
states:
The object in getting these peaches was to secure for the Texas-Gulf r'--i.ii, which
is too far south for the \.,rth (China 1' |" and too far north for the South China type of
peach, by selection from seedlings of Spanish stock in Mexico, a type which would fit
conditions as they exist.,,
These were set out temporarily in field A 1 a(nd in January, 1l'iw,.
were removed to field D 3. They came into bearing in 1,'i 1 and Mr.
Onderdonk was secured as an expert to go through the orchard and
select thlie individual trees that gave promise of b!ing worthy of fur-
ther trial. In thlie orchard there was found to l)e great diversity in
the character of the fruit and tlhe time of ripening. Peaches began
maturing on June 20 and continued until October. Several of the
trees seem to be promising, and there are many others that are to be
passed upon during the coming season. Especially interesting were
two trees of the Spanish type bearing a very superior quality of fruit
and one tree of the Chinese Honey type heavily loaded Iwith fruit,
fully equal to that variety from which all of our Southli China varie-
ties are descendedd.
All the trees marked "undesirable" )by Mr. Onderdonk have been
taken out in order that those remaining may have a better opportu-
nity for growth. Several thousand seeds obtained from the fruit
crop of I 90S have been planted in order to obtain stocks on which to
bud from the more promising trees in the orchard.
These Mexican seedling peaches seemni to be on thlie whole better
adaptled to San Antonio conditions than the commercial varieties
genOIerally planted there. This is particularly true as regards their
a)ilitv to resist the yellowing t)'of the leaves that is probably induced
I)v tHlie excess of limiiie in the soil. If they continue this resistance as
they gronw older t he. may prove toI) be of value as stocks for the ordi-
nary varieties, even it' they yield no new varieties of valhie. Another
p)inlt tof adIvantage which seems to be possessed by these .-,'.,liiin. is
tiat tlhey remained dormant throughout tlie winter of 1907-8, while
,, Mr. onderdonk's expedition to Mexico was made under the direction of the
OIll .. of Seed and PIlant Introduction and ID)istribuition of this Bureau. Thepeaches
x\ere distributed under S. P. 1. numbers 9320 and 9321.
