REPORT OF WORK DONE DURING 1919 UNDER THE LOCAL EXPERIMENT LAW PART I DIRECTOR'S SUMMARIZED REPORT OF WORK IN ALL DEPARTMENTS. BY J. F. DUGGAR, Director of Experiment Station. All of the work reported in this publication was done under the terms of the Local Law passed by the Legislature of Alabama in 1911. This Law provides for a class of experimental work not sufficiently technical nor sufficiently under the im- mediate and constant supervision of trained experi- menters to be supported by the Federal Hatch or Adams funds, even if the whole of those funds were not required for the experimental work conducted in the fields, barns, and laboratories at Auburn. The local experiment work thus provided by the Legislature is more popular and more localized than experiment station work proper, and differs from ex- tension or demonstration work in that the local experi- ment work requires well chosen check or untreated plots and the keeping of careful records for publica- tion for the guidance of farmers cultivating similar soils. PUBLICATIONS The publications issued from the Local Experiment Fund for the fiscal year ending June 30, 1919, consist of the following: Bulletin No. 206: "Grazing Peanuts With Hogs, Versus Market- ing a Crop of Peanuts." Bulletin No. 207: "Local Fertilizer Experiments with Cotton in South Alabama 1914-1918, Inclusive." Circular No. 39: "The Argentine Ant and How to Control It." Circular No 40: "Annual Report of Director of Experiment Sta- tion on the Work Done Under Local Experiment Law in 1918." FIELD. CROPS AND FERTILIZERS. Among the lines of experimental work conducted on 274 farms throughout the state by picked farmers working under the supervision of a representative of the experiment station, the following experiments, among others, were conducted. Corn: Fertilizer experiments, including soil and crop requirements; best combinations; best time of applying nitrate of soda; effects of lime; tests of va- rieties; breeding for increased yield; and multiplica- tion tests to increase for local use the supply of seed systematically bred up by years of careful plant-to- row breeding at Auburn. Cotton: Fertilizer requirements of cotton on each of the principal soil types found in Alabama; best time for applying nitrate of soda; and variety tests. Forage Crops: These include testing, in a number of localities, of an extensive list of forage plants and com- binations of grasses and clovers, and in addition the testing, in a larger number of localities, of smaller numbers of forage plants believed to be especially suit- ed to those localities. Miscellaneous: In addition to the above the follow- ing tests, among others, were also made with staple field crops; fertilizer experiments with peanuts, sweet potatoes, and sugarcane; variety tests of peanuts, oats, rye, wheat, and velvet beans. Lime Requirements of Soils: In addition to field tests intended to throw light on the needs of a number of crops and soils for lime, a large number of samples of soil has been collected for examination in the lab- oratory by a method which indicates the approximate amounts of lime required to overcome the acidity in each soil. On a special trip for this purpose samples were collected during the past year from four counties in south Alabama. In the preceding year the samples collected and examined had been taken from counties in the northern part of the state. These lime surveys and examination of samples will be continued, with a view to testing soils from all counties, and with a hope that the data will afford a basis for the publication of a lime map of the entire state. PLANT BREEDING. Only a part of the time of the plant breeder is given to the local experiment work. He has conducted ex- tensive breeding experiments in four localities in the southern part of the state, with a view to the testing of varieties and strains of cotton as to their relative resistance to the cotton wilt. He has supervised the multiplication, in numerous neighborhoods, of wilt-resistant seed, previously bred up at Auburn or elsewhere. It is a source of gratification that in some localities the progeny of seed systematically bred up at the ex- periment station at Auburn, and subsequently tested out locally under the Local Experiment Law, has to a large extent supplanted other varieties on the farms of the most progressive farmers. ENTOMOLOGY. In this department one of the principal lines of work has been the poisoning of cotton boll weevils with cal- cium arsenate. In three, out of the four, localities in which the re- sults of dusting were carefully investigated, there was notable net profit from this operation in 1919, in spite of almost continuous rainy weather. The method of experimental work consisted in plac- ing a representative of the station on a selected farm to conduct the tests and make the records throughout the late summer and the fall. The entomologist reports that the sweet potato wee- vil, the occurrence of which some years ago in the ex- treme southern part of the state caused justifiable un- easiness, is no longer to be found in Alabama. He also reports that extensive examinations show that there are no pink boll worms in Alabama, as the result of three shipments of cotton made some years ago to Ala- bama fields from the infested region in Texas. ANIMAL HUSBANDRY. The experimental work with beef cattle has contin- ued in cooperation with Judge B. M. Allen on his plant- ation at Allenville. Last year's work consisted of ex- periments to determine the cost of wintering cattle of various ages, the value of peanut meal as compared with cottonseed meal, and the value of low-grade John- 8 son grass hay as compared with sorghum silage. One hundred twenty head of cattle were used in these tests, and, as usual, repetitions will be necessary before the results are sufficiently conclusive for publication. On sandy land at Union Springs experimental work in feeding hogs was continued as heretofore. The third year's results were secured as to the amount of pork produced per acre by grazing on peanuts. The second year's results were secured in feeding to harden the pork of hogs previously grazed on peanuts. In this test a period of seven weeks of exclusive grain feeding was not sufficient to harden all of the hogs, according to the requirements of the St. Louis market. Several lines of feeding and management with poul- try have been continued on a poultry farm at Citron- elle. HORTICULTURE. A part of the time of one man has been available for supervising local experiment work in horticulture. Among the activities of the past year were fertilizer experiments with apples in north Alabama; with peaches in Butler County; and with Satsuma oranges in Baldwin and Mobile Counties. A spraying experi- ment with pecans and the testing of a number of stand- ard and known fruits and nuts were among the local activities of this department. PLANT DISEASES. This department has been concerned with obser- vations and experiments relative to certain diseases of cotton and other economic plants. During the fall the associate pathologist has been engaged in an intensive study of -the leaf spot that is very injurious to bur clover. These studies, not yet completed, seem to indicate that the disease may be prevented by a very simple and inexpensive treatment of the seed. BoYs' CLUB WORK. Before the passage of the Smith-Lever Act of Con- gress in 1914 extension work with boys' clubs was chiefly dependent for support upon an item in the Lo- cal Experiment Law. Now boys' club work is chiefly supported by extension funds provided under the Smith-Lever Act of Congress and state laws related thereto. The total enrollment in 1919, including duplicate membership in more than one kind of boys' agricul- tural clubs, was reported as 7227. DRAINAGE. Cooperation has been continued as heretofore with the Federal Department of Agriculture, whose drain- age engineers, Messrs. Guy A. Hart and Lewis A. Jones, with headquarters at Montgomery, have been succes- sively in charge. They report having made surveys for drainage or terracing systems on 32 properties in 14 counties. They have also made preliminary examinations of 6 large tracts of bottom land with a view to the reclamation and drainage of 40,500 acres of swamp land located in 6 counties. AGRICULTURAL ENGINEERING. After an interim, the position of agricultural engi- neer was filled September 1, 1919, by the appointment of Professor M. L. Nichols. In the remaining four months of the year he has made plans for future work, and has made a beginning in some lines of experiment- al inquiry. One of these is a determination of the most practicable methods of repairing and roofing old tenant houses and other farm buildings. Some work has been done in adapting machinery to the hulling of bur clover seed as a means of improving its germni- nating power and in order to make more practicable the treatment of the seed for the prevention of the leaf disease of bur clover. 10 TREASURER'S REPORT, LOCAL EXPERIMENT FUND FOR THE YEAR 1919.

Duggar, Alabama Experiment Station, Auburn, Alabama. Sir: The following is submitted as a report on the work carried on under the Local Experiment Fund in 1919 by the Agricultural Department of the Alabama Experi- ment Station: Lines of Experiments: Three or more experiments with some field crop were conducted in every county in the state, with the exception of Lee. The total number of experiments arranged for 1919 was 422, with 268 ex- perimenters. Lines of Experimentation: Below are listed the thir- ty-nine distinct lines of experiments which were con- ducted during the year, 1919: Corn, complete fertilizer experiments. Corn, complete lime experiments. Corn, time of applying nitrate of soda. Corn, sources of nitrogen experiments. Corn, extensive variety experiments. Corn, short variety experiments.

Rye, extensive variety experiments. Soybeans, short variety experiments. Sudan grass experiments. Sugar cane, complete fertilizer experiments. Sweet potatoes, complete fertilizer experiments. Velvet beans, short variety experiments. Vetch, short variety experiments. Wheat, extensive variety experiments. Wheat, multiplication. Forage Crop Experiments: Special attention is being given to winter forage crop experiments. The results from this line of experimentation during the past sea- son give very valuable information in regard to some of the vetches, true clovers, wheat, oats and rye. De- tailed notes and pictures were secured of each of the tests. Soil Acidity Studies: Continuing the soil acidity work, started in 1916 in cooperation with the Division of Soils, many soil samples were taken in Butler, Cone- cuh, Escambia and Mobile counties during the summer of 1919. These samples are to be used for laboratory studies, especially with reference to their need for lime. Further sampling of the various soils of Alabama will be done from time to time. Publications and Papers: Bulletin No. 207, "Local Fertilizer Experiments with Cotton in South Alabama, 1914-1918, Inclusive," has been printed and distributed since the last report of this kind. Other bulletins show- ing the results of the experiments made by this Division will be published this season. A paper, on the "Need of Cotton for Potash on Coast- al Plain Soils, giving an average of the one hundred conclusive experiments in South Alabama, 1911-1918, inclusive, was presented at the meeting of Southern Ag- ricultural Workers in Birmingham last year. Experimenters: When Local Experiment work was begun by this Division it was very dificult to secure men who were both satisfactory experimenters and in posi- tion to make experiments more than one year. Much of this difficulty has now been eliminated. In 1919 more than 74 percent of the experiments located by the Superintendent of Cooperative Experiments in Agricul- ture were on farms of men who had previously con- ducted experiments. These men, as well as the other 25 13 ,or 26 percent, are almost without exception men who are interested in the experiments for the actual benefit they will derive from them in their farming operations. These experimenters are men who are capable, respon- sible and careful; and quite a number of the 268 experi- ienters have conducted the same experiments on their farms from five to eight years. They realize the value of persistent repetitions, of carefulness and of accuracy in making experiments and are usually willing to in- convenience themselves, if need be, in order to get the information from these experiments. Respectfully submitted, J. T. WILLIAMSON, Supt. of Co-operative Experiments in Agriculture. REPORT OF ASSOCIATE PLANT BREEDER Professor J. F. Duggar, Director, Alabama Experiment Station, Auburn, Alabama. Sir: I submit the following report of the work done in Plant Breeding under the Local Experiment Fund dur- ing the year 1919. The breeding of cotton for wilt resistance under boll weevil conditions was continued with additienal at- tention to a better staple. Plant-to-row tests and in- crease plots from previous row tests of wilt resistant va- rieties were conducted cooperatively with farmers in four counties as follows: Cook 307-6 wilt-resistant, in Macon county; Cook 307-6 wilt resistant, in Barbour county; Toole wilt resistant in Henry county, and Dixie wilt resistant in Crenshaw county. The planting of these row tests was personally supervised, and they were visited several times during the year and compar- ative notes made on the rows. In the fall about thirty individual plant selections were made from each of the row tests and increase plots. A few individual plant selections were made from cotton multiplication experiments. The best strains from the plant-to-row tests of the several varieties are isolated, multiplied rapidly and offered for sale by lo- cal breeders, thus bringing into general cultivation the best strains bred up by the Experiment Station. Extensive variety tests of wilt resistant cotton were conducted co-operatively with farmers in Macon, Rus- sell, Autauga, Henry and Crenshaw counties. In each of these experiments sixteen varieties of wilt resistant cotton collected from different parts of Alabama and other states were tested. All varieties used in 1918 were repeated in the 1919 experiments when possible. Eight short variety tests consisting of three of the best wilt-resistant varieties of cotton were conducted in different parts of the wilt infected area of Alabama. The few best varieties as shown by the extensive varie- ty tests are the ones used in the short tests. A number of isolation experiments of wilt resistant varieties of cotton were placed with farmers with a view of rapidly multiplying the seed of varieties par- ticularly suited to the different localities. Respectfully submitted, HI. B. TISDALE, Associate Plant Breeder. REPORT OF ENTOMOLOGIST W. E. HINDS Auburn, Ala., Dec. 20, 1919. Prof. J. F. Duggar, Director, Alabama Experiment Station, Auburn, Ala. Sir: Herewith I submit a brief report of the principal En- tomological activities under Local Experiment Funds for the calendar year of 1919. 1. Boll Weevil: Soon after the beginning of the 1919 season it became apparent to us that the boll wee- vil was likely to survive hibernation in large numbers and the situation appeared to be favorable for heavy damage during the season of 1919. We therefore, un- dertook to warn farmers to this effect and to cooperate in the general campaign for reduction of acreage plant- ed in cotton, through meetings with the bankers, far- mers, and others, in every way possible. Of course, we could not anticipate the unusually heavy rainfall oc- curring during July and August 1919. This rainfall however, not only favored the multiplication of the weevils, but prevented the setting of cotton even more effectively than the weevil would have done without the rainfall. Our principal work with the weevil this year has been in connection with the demonstration of the possibility and practicability of controlling the weevil by dust- ing the cotton with Calcium Arsenate, according to plans recommended by the U. S. Bureau of Entomolo- gy. This work was first started in 1918, and in that season did not give us profitable results, mainly due to dry weather occurring in the early part of the fruit- ing season and continuing for several weeks. This drouth controlled the weevil to such an extent that poi- soning was not necessary to secure a practically nor- mal crop. In 1919, however, the situation was radical- ly different, and we found that farmers were deeply interested in the question of poisoning cotton, but com- paratively few of them were willing to take steps to provide the machinery and the poison necessary until the matter had been proven to their satisfaction. We considered therefore, that this project was of larger fi- nancial importance than any other to which we could 16 devote our attention. Naturally, a matter of this kind required the entire season to put through the test. This work was planned and carried on to cover as many representative points in the State as possible, and to apply to as many varied soil and cultural conditions as we might be able to cover within the limits of our funds. As a general result from this work, we can state that at Dothan, Alabama, on Spann Bros'. Plantation, the increased yield as a result of dusting showed a value ranging up to better than $20.00 per acre. At Allen- ville, on A. M. Collins' plantation similar results were ,obtained. At Orrville, on J. E. Dunnaway s plantation, where the progress of the work was in charge of a special agent, working for the Niagara Sprayer Co., but who cooperated by keeping records and giving us, a report regarding his work, we find that on an area of 75 acres dusted there is an average profit of better ;than '22.00 per acre. At Prattville on the McQueen Smith Plantation, the expense of conducting the work ranged somewhat higher and the results were some- ,what less than at other localities, so that it is probable that little, if any profit will be realized at that point. However, for the work as a whole, we can state defi- nitely that the results are extremely encouraging in spite of the most difficult season, so far as late fall con-
