CLIMATIC CONDITIONS.

The season of 1913 was generally favorable to crop production
in the San Antonio region of Texas. More than the usual rain-
fall in December, 1912, put the soil in good condition to receive
the January and February rains, which were practically normal
in quantity. At pLinting time the soil was in excellent coiiondition, and
rapid and uniform germination and an excellent stand of nearly all

excellent growth of green material was made before the peas were
plowed under the following firing. Figure 3 shows the appearance
of the peas at the time of plowing under. The excellent results
obtained with this crop during 1913 and previously have shown that
field peas appear to be the most satisfactory legume that can be
grown as a catch crop in the San Antonio region. How valuable a
green-manure crop this legume will prove to be remains to be deter-
mined, but there seems to be no question about its ablility to pro-
duce a heavy growth. At the present time the peas are under trial
as ai green-manure crop in five rotations and are being grown during
the winter on one plat which is cropped ;iyin;illy to cotton.
SThese are frequently known as Canada field peas.

TIe dilferen i rotatimis have wtit been under trial a sufficient length
of timne to determine which are best and thie best sequence for the
,various crops growiL in the region. However, tihe results so far
obtained show ti0e deride! s.uIperiowity of crop rotation as compared
with 1-crop systemnis. It lbas been thie practice in the rotation experi-
mients to have one or more plats on wlicli each crop is grown con-
tinuously with which to compare tire yields from thie same crop
grown in various rotations. Thie fields have been uniformly higher
wlhen ltie crops have been grown in rotation than when thie crops
were grown continuousVly on the sam,' land.
SUBSOILING.

The results obtained from stibsoiling were corroborative of results
previously publishedd'
Tihe average yields of corn and cotton from land subsoiled and
from land not subsoiled were practically the same, and subsoiling
decreased the yield of oats for both hay and grain.
FALLOWING.

The results of fallowing were substantially the same as in previous
years. Thie yields of corn, cotton, and oats grown on fallowed land,
together with thie average yield (of each crop from all of the rotation
experiments, are shown in Table III.

RESISTANT STOCKS.
The resistance or nonresistance of the various stocks to the adverse
soil conditions was more pronounced in 191.3 than ever befor.. The
testiing of tie various resistant varieties as stocks is to be continued,
for it is evident that there is great. variation in the different fruits
and varieties of the same species as to their resistance t(I disease.
A collection of five different lots of peach seedlings was made during
the year, and these are to be tested in an orchard devoted to resistant
stocks.
The fruit stocks that are receiving special attention are peaches,
grapes, walnuts, plums, persimmons, and pears. The results obtained

bamboos, and other semitropical plants. About 150 different species are being tested.
along this line indicate that by the use of proper stocks niminy fruits
heretofore considered not adapted to local conditions may be pro-
duced and also that many new fruits may be added to the list.
ORNAMENTALS.
Tim, ti.ti1ig of ornamental trees and shrubs suitable fir the
San Antonio region is receiving much attention, and iimany (if tlhe
plantings have reached the stage where their adaptability t, the local
conditions can 1)e determined. There are under trial at present 149
diffire.t. species, as follows: Mi-'rraluiis species which were secured
lii-r.ly f!.,mii various nurseries, 65; importations of the Office of
Foreign Seed and Plant Introduction, 30 species; yuc(.ls.l, agaves, etc.,
most of which are native, 19 species; palms, 19 species; anlld native
species, most of which may be used as ornamelililt ;il, 16. In addition
to the above there are under trial 86 varieties of roses. A view of

VARIETY TEST OF COTTON.

A variety test of cotton, which was practically a duplicate of the
test made in 1912, was conducted in 1913. Table V gives t1w results
of this test. The varieties were planted in rows 16 rods long.

As shown in Table V, the San Antonio selections of the Triumph
variety ranked high during both years. Considering both yield and
quality, the Triumph is the most desirable variety tested during the
past two years. The Virgatus gave thle highest yield in 1912, but the
lint produced is very short, and consequently the variety wu- not ii-
cluded in the test in 1913.
A test of 10 varieties of long-staple Upland cotton was made in
cooperation with the Office of Acclimatization and Adaptation of
Crop Plants. Thie-e varieties were plunt,.,l on field D3, aInd it. was
intended that they should be grwnii under irriguitin,. They received
a light irrigation soon after ]plantiing, but ,wilig to the heavy spring
rains it was not necessary to irri-atle again unt il late in thlie season.
But at this time the boll weevils appeared in such numbers that it
was not deemed advisable to stimulate an excessive vetzitiv. growt h,
so that no further irrigatii'" was done. Table VI gives tlt. results
of the test.

SPACING OF MILO.

The successful production of grain sorghum depends upon early
maturity because of the ravages of the .,,rghunm midge.' Milo tillers
very freely at San Antonio, especially when the plants are spaced
some distance apart. The tillers flower v.v\vrail days later than the
main stalk, lengthening the season of the crop, and as the margin
between the fl \\ crilng of the plants and the emergence of the sorghum
inidge is frequently very short it is of importance that th. crop be
matured as uniformly and quickly as possible.
In 1913 ten plats of milo were devoted to a test to dettrnmine the
effect upon the tillers of spacing the plants to various distances.
It was found that the plants can be placed much closer together
than is generally supposed without decrl asing the yield. Where the
plants were relatively close together in the row the number of tillers
was very materially decreased. As the tillers are later in maturing
than the main stalk, earlier and more uniform ripening was obtained
with close spacing than where wide spacing was practiced. Table
IX gives a summary of the results.
