By S I i Basting* Fa - dent INTBODUCTION. The work of the San Antonio Experiment Farm in 1913 was con- tinued along the same general lines as deecrihed in the report for 1912.' The more important experiments were those in (Top rotation and tillage; breeding and variety testing of cotton and of coin: rate of Beedingand variety testing of sorghum : testing of varieties of peacl plums, apricots, persimmons, grapes, walnuts, almonds, Chinese dates, and some other fruits of lesser importance; and testing of resistant stocks for these fruits. Additions were also made to the ornamental plantings. ^\" i 1 1 1 the exception of fruit and cotton the crop yields in 1913 were unusually heavy. The corn yield was the largest obtained during the seven years thai the experimenl farm has been operated. The yields of forage from both oats and Borghum were the heaviest bo far obtained with the exception of those secured in 1908. The avert yield of milo exceeded that of 1912 by 7.7 bushels per acre and \\a* the largest bo far obtained. The yields of milo have been extremely satisfactory and show conclusively that this crop is the most profitable grain crop for the San Antonio region. In the rate-of-seeding test with milo it was found that with relatively close spacing of the plant-, in the row tin- crop matured more uniformly and higher yields were obtained, chiefly because of earlier maturity and consequent escape from the ravages of the sorghum midge, which ha- been the princi- pal menace to the production of grain Borghum in this region. The effeel of crop rotation and various tillage methods i- becoming more noticeable. Summer fallowing and subsoiling have uniformly failed to justify the operations.

There was a very light fruit crop in 1913, owing to late spring frosts. Only two plum varieties fruited and even the best peach varieties fruited but sparingly, while the others set no fruit. A heavy crop of fruit was obtained from the pomegranate varieties, and one variety of cit range, the Rusk, fruited this season for the first time. The work carried on by the Office of Acclimatization and Adaptation of Crop Plants has shown that a closer plant- ing of cotton in the row than has been the practice gives higher yields. Tn the variety test of short-staple cot- tons, a locally se- lected Triumph stock gave the high- est yield.

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 rams, which were practically normal in quantity. At planting time the soil was in excellent condition, and rapid and uniform germination and an excellent stand of nearly all crops resulted. The distribution of the Bpring rainfall was favorable to the development of plant growth, and the heavy precipitation in June resulted in high yields of corn and forage crops. At the Bame time the abundance of moisture caused an excessive vegetative growth of cotton and favored the development <<( the cotton l>"ll weevil to Buch an extent thai the weevil damage at the experiment farm was much greater than it had I n for Beveral years past. \ droughl lasting through Julj and the greater pari of August and the unusual abundance of l>"ll weevils combined t" lessen the cotton crop \ ery materiaUy . During the months of September and Ocl »ber unusually heavy rains fell, causing serious floods in the San Ajitonio and adjacent rivers. Such ram- were favorable i<> the development of late forage crops, and abundant feed was made from the second-crop growth of Borghum and Johnson grass. The re oainder of the year was char acterizcd l>\ heavy rains, which caused much delaj in fall work through* in the section, and in some parts of Texas disastrous floods occurred. During the year the total precipitation at the experiment farm was :;ii.71 inches. This was 12.05 inches above the average for the seven years 1907 to 1913, inclusive, and about lo inches above the normal for u 20-year period, as reported by the United States Weather Bureau station at San Antonio. Owing perhaps to the excessive precipitation, the evaporation a1 the experiment farm was somewhat less than during anj year of the last six. The t'>tal evaporation for 1913 was 58.68 inches, while the average for the year- 1907 to 1913, inclusive, i- 65.88 inches. The temperature in the spring of L913 was unusually low, the last hilling frost occurring on March 17. The latest frost in spring during the preceding sis year- was on February 27, which occurred in 1912. This late frosl in 1913 resulted in freezing the corn, which was about 2 inches high. New growth started uj>, however, so thai replanting was not necessary. This frost also killed practically the entire fruit crop in the San Antonio region. The first killing frosl in autumn came on October 27, when a mini- mum temperature of 29 F. was recorded. This resulted in killing to the ground all the tender crops. The meteorological observations made at the experiment farm are carried on in cooperation with the Biophysical Laboratory of the Bureau of Plant Industry.

The crop season of 1913 com- pleted the fifth year of these experiments. The results so far ob turned warranted the adding of four new rotations al the opening <»f tlic present season. Tun I year rotations and two •'! vein- rotations wi'iv added to those already under trial, bo that at the present time the work occupies 98 quarter-acre plats. There is now a total of •';■"> different rotations of \ an ing lengths, and there are I I plats continu- ous!) cropped to the same crops. The favorable results obtained with Dwarf milo in the rotation experiments in the season of 1912, when it was substituted for coin in live rotation-- and for the first time grown in these experiments, made it desirable to reduce Mill further the Dumber of plats of corn. In 1913, Dwarf milo was therefore substituted for corn in five of the old rotations and included ill the four new rotations. The results ol> tamed from this en>|> in 1913 were very satisfactory. During the year, which was an unusually favorable one I'm- Indian corn in the San Antonio region, the average yield from i I plats of Dwarf milo was 17.7 bushels per acre, as compared with 34.9 bushels of corn per acre, an average from 21 plats, in reality the milo was at a much greater disadvantage than corn, for the rains occurring after June L5 came as the corn was beginning to tassel and when the crop was feeling the effects of the lack of moisture. If these rains had doI occurred, there probably would have been an extremely poor yield of corn. ()n (lie other hand, the milo was practically mature by June 15, bo thai the rains occurring thereafter, and which insured the corn crop, were of little, if any, benefit to the milo crop. Four years' experience has demonstrated the undesirabihtj of growing cow pea- as a summer crop after oats or corn, on account, of Bummer drought. At. the beginning of the season of 1913, therefore, cowpeas as a catch crop after oats or corn were eliminated from all but two rotations in which cowpeas had previously been planted after oats. During the five year- the rotation work has been ducted in its present form there has never been a season when cow- peas made a crop when planted after corn, and only one, L913, when they made sufficient growth to be of any value as a green-manure crop when planted after oats. During most summers the soil has been so dry as to make useless the planting of cowpeas after corn, and the same has been true of cow pea- after oat- dining three of the five year-. Figure 2 .-how- the growth of cow pea- after oats during the season of 1912. During 1913, cowpeas planted after oats made excellent, growth, but. the season was a most, unusual one. the pre- i cipitation during September and October being 13.47 inches, which is much above the normal for those months. There was sufficient moisture at planting time, about July 1, to insure perfect germination. The plants made some growth and then remained practically the same size until heavy rains came in September. Field peas ' have been grown at the experiment farm during five years, and very favorable results have been obtained. 3 The abundant growth of green material indicated that this pea would make a desir- able, green-manure crop. Previous to 1913 no trials were made with this legume as a green-manure crop. In the fall of 1912 hold peas a winter cover and green-manure crop were introduced in two rota- tions, and two plats wore planted to peas on October 31, 1912. An Fig. 2. — Plat of cow-peas in rotation experiments, 103 days after planting , at the San Antonio Experiment Farm, showing the small growth made during the dry weather of summer. Photographed October S, 1912. (Compare with figure 3.) excellent growth of green material was made before the peas were plowed under the following spring. Figure 3 shows the appearand 1 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 ability to pro- duce a heavy growth. At the present time the peas are under trial as a green-manure crop in five rotations and are being grown during the winter on one plat which is cropped annually to cotton. 1 These arc frequently known as Canada field peas. 2 See'' Foragc-cnip experiments at the San Antonio Field Station," U. S. Dept. obAgriculture, Bureau of Plant Industry Circular 106, 1313. Tho favorable results obtained with Sudan during 1911 and 1012 made it desirable t" introduce this crop into the rotation ■ ments.

However, the results so far obtained show the decided superiority of crop rotation as compared with 1-crop systems. It has been the practice in the rotation experi- ments to have one or more plats on wluch each crop is grown con- tinuously with which to compare the yields from the same crop grown in various rotations. The yields have been uniformly higher when the crops have been grown in rotation than when the crops were grown continuously on the same land. SUBSOHJNG. The results obtained from subsoiling wore corroborative of results previously published. 1 The 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. The yields of corn, cotton, and oats grown on fallowed land, together with the average yield of each crop from all of the rotation experiments, are shown in Table III.

The increased yield of oats on fallowed land appears to be due to slower growth during the early part of the season and to the consequent lessened damage from lodging or from late drought. Oats on the other plats made such a luxuriant vegetative growth during the early part of the season that they lodged badly and the 1 Experiments in subsoiling at S:in Antonio. In 1". S.

It was observed that fallowing did not make the conditions more favorable for plant growth throughout the season as a whole, but thai it was the depressing effect on the vegetative growth earlj in the season which resulted in a higher yield of grain. HOBTIC1 i.n k\i. WOBK. Owing to late spring frosts which were preceded l>\ warm weather, there was practically no fruit crop. Onlj a few peaches were found on the trees of the Mexican seedling peach orchard, and the same was true of the other peach varieties. Only two varieties of plums, :.miegranates in the on-hard at the San Antonio Experiment K.i tin- Gonzales and Terrell, bore fruit. The former 9et a heavy crop. The Gonzales plum i- undoubtedly the most reliable variety thai has been under trial. The Rusk citrange fruited for the first time in 1913. Tin- citrange i- on,- of the hardiest of the citrus fruit-, and this variety is particularly well adapted to San Antonio conditions. POMBGBAN Ml -. A heavy crop wad matured in 1913 from most of the pome- granate varieties that have fruited. The San Pipetos, !>•■ dative, and Dessia varieties have produced the hot fruit- of the collection of nine varieties. The Papershell and Subacid varieties have ma- tured the heaviest crop-. Where strong, vigorous plants are desired, the San Pipetos and De dative should be planted (fig. t 10 RESISTANT STOCKS. The resistance or nonresistance of the various stocks to the adverse soil conditions was more pronounced in 191.'3 than ever before. The testing of the 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 to disease. A collect ion of five different lots of peach seedlings was made during the year, and these are to he 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 Fig. 5.— View of ornamental plantings at the San Antonio Experiment Farm, showing palms, yuccas, bamboos, and other semitropical plants. About 150 different species are being tested. along this line indicate that by the use of proper stocks many 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. The testing of ornamental trees and shrubs suitable for the San Antonio region is receiving much attention, and many of the plantings have reached the stage where their adaptability to the local conditions can be determined. There are under trial at present 149 different species, as follows: Miscellaneous species which were secured largely from various nurseries, 0,"); importations of the Office of Foreign Seed and Plant Introduction, 30 species; yuccas, agaves, etc.. most of which are native, 19 species; palms, 19 species: .and native species, most of which may be used as ornamentals, 10. In addition to the above there are under trial SO varieties of roses. A view of a part of the ornamental plantings is shown in figure .">.

The object of these experiments bas been to tesl the possibility of secur- ing curlier crops l>\ controlling the formation of the vegetative branches. Ii bas been found that the vegetative branches can be suppressed l>\ thinning the cotton Later and leaving the plants closer together in the rows than bas been customs ■ . This work is carried on by the Office of Acclimatization and Adaptation of Crop Plants. Recent publications by O. F. Cook 1 give the results of these experi- ments carried on in L912and 1913. In these publications it is shown that closer planting than i- customary gives higher yields. Closer Bpacing of the plants in the i'du has been adopted in the field plantings at the Btation, with results which seem to justify the more extensive use of this method in the section. The distance apart which the plants have heretofore been spaced was 24 inches, but this distance has been reduced to 1- inches or less. Mr. R. M. Meade, of the Office of Acclimatization and Adaptation of Crop Plants, has furnished some figures on the results of some experiments carried on at the San Antonio Experiment Farm to determine the mosl desirable distances to which to thin the plants in the row.

Considering both yield and quality, the Triumph is the most desirable variety tested during the past two years. The Virgatus gave the highest yield in 1912, but the lint produced is very short, and consequently the variety was not in- 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. These varieties were planted on field D3, and it was intended that they should be grown under irrigation. They received a light irrigation soon after planting, but owing to the heavy spring rains it was not necessary to irrigate again until late in the season. But at this time the boll weevils appeared in such numbers that it was not deemed advisable to stimulate an excessive vegetative growth, so that no further irrigating was done.

The successful production of grain sorghum depends upon early maturity because of the ravages of the sorghum midge. 1 Milo tillers very freely at San Antonio, especially when the plants are spaced some distance apart. The tillers flower several days later than the main stalk, lengthening the season of the crop, and as the margin between the flowering of the plants and the emergence of the sorghum midge is frequently very short it is of importance that the crop be matured as uniformly and quickly as possible. In 1913 ten plats of milo were devoted to a test to determine 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 decreasing 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.

The mosl important effecl of spacing shown in the table was the decreased number of heads and of tillers per plant where the plants were relativelj close togethei within the row. The benefit derived from having few tillers lies in the fact thai few tillers favor earlj and uniform maturity. On June 28, when 90 per, cent of the heads on the close spaced plant - (those left un thinned and those thinned to 2 inches) were ripe, less than 70 per cenl of the heads on the wider spaced plant- had reached maturity. Earlj and uniform maturity lessens the danger of damage bj the sorghum midge, and th<' results obtained in 1913 stronglj indicate thai closi i spacing than has usuall) been practiced will resull in earlit r and more uniform maturit \ . \ UMI.TY TEST OF CORN.
