The following is a summary of some experiments with wheat made at the Agricultural Experiment Station of the University of Illi- nois, Champaign, on fertile, dark colored prairie soil, for the season of 1891-92; and of experiments made at Flora, Odin, Belleville, and DuQuoin, to test the effect of manures on wheat. The year 1891 was one of unusual drouth, continuing until Novem- ber. The winter was rather mild, with a fair rain-fall. The spring of 1892 was characterized by unusually heavy rains. 105 io6 BULLETIN NO. 22. [ August^ TEMPERATURE AND RAINFALL, JULY, 1891, TO JUNE, 1892. 1891 and 1892. Average for 10 years. Rain- fall.

The land was plowed in August, was disked twice, harrowed, and rolled before seeding. The wheat made but feeble growth in the autumn. The growth of straw in the spring was heavy. Much of the wheat lodged badly. Variety Tests. Sixty varieties were sown on one-tenth acre plats, and 12 of Carter's cross-bred wheats in smaller plats. None of these last were worth harvesting. Several other varieties, generally of for- eign origin, failed. Fifty-six plats, representing 48 varieties as named, gave an average yield of 29 bu. per acre. The largest yield was at the rate of 35.4 bu; the smallest, 16.3 bu.; the next smallest, 22 bu. Twenty-two plats yielded at the rate of over 30 bu.; six, less than 25 bu. each. All of the wheat was light in weight; 58 Ib. a bushel being the highest, 51.25 Ib. the lightest weight; the wheat from 18 plats weighing less than 55 Ib. a bu. Twenty-five plats of bearded wheat gave an average yield of 30.8 bu.; 28 plats of bald wheat an average of 27.5 bu. an acre. Six varieties were classed as white wheat. These gave an average yield of 25.8 bu. an acre, the largest yield being 30.3 bu. Of the red bearded varieties the following gave yields of 30 bu. or more an acre, averaging over 33 bu.: Hindustan, Diehl Mediterranean, Deitz, Tuscan Island, Lehigh, Crate, Tasmanian red, velvet chaff, nig- ger, golden cross, new longberry Wabash, and Lebanon. Of red bald varieties Poole, CurrelPs prolific, longberry, and im- proved rice gave yields of 30 to 32 bu. an acre. Of white bald varieties golden prolific gave 30 bu., and of the white bearded Democrat gave the same yield. These plats were drilled at the rate of six pecks an acre, from Sept. 25th to Sept. 29th. 1892.] WHEAT EXPERIMENTS, I, IO7 Thickness of Seeding. Seeding at the rate of 4 pecks an acre gave yields of 24.7 bu. an acre; 5 pecks, 29 bu.; six, 28 bu.; eight, 27.8 bu. In a series of years seeding at the rate of from 5 to 6 pecks an acre has given the best results. Time of Solving. Wheat sown Sept. 2d gave a yield of 29 bu.; Sept. nth, 28.5 bu.; Sept. 2oth, 28.7 bu.; Oct. 5th, 27.2 bu.; Oct. i3th, 21.7 bu. The yield of straw steadily decreased from earliest to latest sowing. In trials for several years no material difference has been found in the yields of wheat sown any time in September. Depth of Seeding. Little difference in yield was found when the wheat was covered one inch or three inches. That covered five inches yielded considerably less. Effect of Fertilizers. Application of stable manures, bone meal, and blood and bone fertilizers gave litttle or no increase in yield of wheat on the Station grounds. In trials in southern Illinois stable man- ures produced a marked effect and the other fertilizers sufficient yields to make further trials advisable. Effect of Time of Harvesting. Harvesting at different stages of ripeness showed a constant increase in both yield and size of berry from earliest up to latest. At the latest date the wheat was " dead " ripe. Experiment No. 65. Wheat, Quantity of Seed. For four successive years an experiment has been tried to test the effect of sowing different quantities of seed per acre. In 1891 six plats were drilled Oct. 6th as nearly as practicable at the rates indicated in the table, which also gives the results. These show that the largest yield of both grain and straw came from seeding at the rate of five pecks per acre. The average results from duplicate plats for each of the four years are given in a second table. In no year has there been any remarkable variation in yield caused by difference in rate of seeding, unless 1891 be an exception. In that year there was an extreme difference of over seven bushels per acre. For two years the stubs after cutting have been counted on several square feet on each plat. Considerable variation has been shown, but the numbers have not in all cases varied with the rate of seeding. YIELD OF WHEAT FROM DIFFERENT AMOUNTS OF SEED, 1891-2. ~ p ? Rate of seeding.

Wheat, Time of Sowing. Trials of the influence on yield of grain and straw of sowing wheat at different dates have been made for four years. In the trials for 1891-92, the land used had produced a large crop of oats in 1891. It was plowed during August. Each plat was disked twice, harrowed, and rolled just before the wheat was drilled in. While all the plats made but feeble growth during the autumn because of the drouth, the earlier sown made the best growth and appeared most vigorous in the spring.

(The yield of the earliest sown plat in 1891 was some- what decreased by the effect of shade of trees near by.) The yield of straw has generally decreased from the first to the last sowing. Experiment No. 67. Wheat, Depth of Solving. To compare the growth and yield of wheat sown at different depths nine rows 12 in. apart, each one rod long, were planted Oct. 8, 1891, each row with 198 kernels of selected seed wheat, or one kernel to each inch in the rows. The seed in rows i, 2, and 3 was covered one inch deep; in rows 4, 5, and 6, three inches; in 7, 8, and 9, five inches. An extra row was planted on each side of the plat. The wheat made but feeble growth in the autumn and April ist was in poor condition. It was cut July I4th, when it was all ripe and all standing. The table gives details of the results. There were considerable variations in the rows covered to the same depth. In no case did much more than one-third of the kernels pro- duce plants which came to maturity. The average number of straws in each stool was low, five being the highest in any one row. While the yields of adjoining rows varied more than the yields from planting at different depths, slightly the best results came from the three rows covered one inch deep. A like result was found in the year previous. The unsatisfactory results usually obtained from experiments in which only small numbers of plants or animals are used is well illus- trated in this table.

Wheat, Effect of Fertilizers. [At Station.] The effect of different kinds of manures on wheat has been tried on the Station grounds for four years. For the season of 1891 eight plats were used, each one-fourth of an acre in extent. On each of two plats 100 Ib. bone meal was applied; on each of two others 100 Ib. bone and blood. These manures were sown broadcast by hand Oct. yth, immediately before the wheat was sown. In January, 1892, five loads of rather coarse and strawy manure mostly from the horse stables, was applied to one plat. On three plats no manure was applied. No appreciable difference in the condition of no BULLETIN NO. 22. [August, the wheat on the different plats was observed either in the autumn or early spring. The table gives the results. While there are considerable differences in the yields of the plats, these are believed to be owing more to the differences in soil than to the effect of manures applied. The plats were each 2x20 rods. Plats 68 and 72, 69 and 73, 70 and 74, and 71 and 75 were side by side. Except in plats 70 and 74 there was in no case a difference of one bushel per acre in the yield of the plats of any pair of plats. In this case the plat to which nothing had been applied yielded at the rate of 3.2 bu. per acre more than the adjoining plat on which manure had been applied. The wheat on the plat to which barn yard manure was applied lodged much more than that on the adjoining plat. The application to wheat of no form of the commercial fertilizers yet tested at the Station has proved profitable. Samples of the two commercial fertilizers used 5 as analyzed by E. H. Farrington, Chemist of the Station, had the following composition: Bone meal.

Wheat, Effect of Fertilizers. [Southern Illinois.] For four years past trials of different commercial fertilizers for wheat have been made at different places in the southern part of the state, Flora, Odin, Nashville, Belleville, and DuQuoin. With the excep- tion of the land near Belleville, all the trials have been on the level, light colored soils, with very compact sub-soils, characteristic of central south- ern Illinois. For 1891 and 1892 the experiments were tried on the farms of W. W. Bowler, Flora; A. M. Woodward, Odin; H. Horn, DuQuoin; and Fred Helms, Belleville. Mr. Helms' farm is naturally very fertile. In each case eight one-fourth acre plats were laid off side by side in fields to be sown with wheat. The plats were long and narrow. IS 9 2.] WHEAT EXPERIMENTS, 1891-2. The fertilizers were applied as follows: To plat No. i, 5 loads stable manure. " " " 2, nothing. " " 3, 100 Ih. bone meal. " " " 4, 100 Ib. blood and bone. " " 5, nothing. u " " 6, 100 Ib. bone meal. " " " 7, 100 Ib. blood and bone. " " " 8, nothing. The bone meal and blood and bone were the same as used in Experi- ment No. 62. In general the soil of the different tracts seemed uniform. Aside from the fertilizing, the treatment of all the plats was the same throughout. The table gives the results, which, are not uniform at the different places, nor in accordance with the experience in previous years. As in former years, the plats with barnyard manure gave the best results, ex- cept at Flora. At Odin the yield from the plat to which stable manure was applied was at the rate of 14 bu. in excess of the plats to which the commercial fertilizers were applied, and nearly 17 bu. more than the average of the plats to which nothing was applied. In all four cases the stable manure produced a marked increase of yield over that from the unmanured plats, the average yield from the four plats treated with stable manure being at the rate of 28.5 bu. per acre, while that from the 12 plats having no manure was at the rate of iS.8 bu. per acre. The average yield of the 16 plats to which commercial fertilizers had been applied was at the rate of 24 bu. per acre; the yield of the eight plats receiving blood and bone averaged 25.1 bu. per acre; that of the eight plats receiving bone meal averaged 22.8 bu. per acre. A considerable variation is shown in the yield of the different plats treated with the same fertilizers, as well as in the plats without any fer- tilizer. At Odin the two plats to which bone meal was applied gave a less yield than the three to which nothing had been applied, while each of the two plats to which bone and blood had been applied gave a much larger yield than either one of those to which nothing had been applied. As a whole these results are more favorable to the use of these commercial fertilizers than those in any other years. As in each of the former years, these results emphasize the great value of stable manure. YIELD PER ACRE, Bu., FROM FERTILIZED AND UNFERTILIZED PLATS, 1891-2.

Wheat, Test of Varieties. To compare the yield and other qualities of varieties, 62 plats of one-tenth of an acre each were sown from Sept. 25 to Sept. 29, 1891, with what were named as varieties, with duplicates, and with four mix- tures, each of several varieties possessing similar qualities. These plats were in the same field as that in which all the other experiments with wheat at the Station were tried, and the preparation of the soil was the same as reported in those experiments. The rate of seeding in each case was six pecks per acre, as nearly as practicable. Most of the varieties were obtained from the Ohio Agricultural Ex- periment Station, at Columbus. A few came from the Pennsylvania Agricultural Experiment Station, at State College, and a few from dif- ferent individuals. In a number of cases samples of wheat received under different names very closely resemble each other, not only in kernel but in stalk, head, time of ripening, and yield. In addition to these varieties twelve cross bred varieties, originated by Carter, of London, England, the seed of which had been received in 1890 and sown that autumn, were sown in smaller plats. The seed as received from England was very attractive, the kernels being large, plump, and of good color. The product at the first harvest was unsatis- factory, all the varieties maturing too late to make them desirable, and the kernels being much shriveled. All the varieties failed almost en- tirely in the second season's trial. No one of the plats was worth harvesting and in several of them scarcely any heads were produced. The tables give the results of these trials. The date of ripening, yields both of straw and grain, and the weight per bushel of nearly all the varieties tested here are given from the reports of the trials of the same varieties for the same season at the Ohio Station, at Columbus, and for ten varieties from the report of the tests at the Indiana Station, at LaFayette. It is noticeable that without exception the time of ripening of any given variety was several days later at this Station than at either of the others, in several cases the difference being from ten to thirteen days. The wheat harvest in this vicinity was unusually late in 1892. In the case of a number of varieties the yields at the different stations are quite uniform; in others, there are striking differences. At this Station the average yield of the plats was good, 56 plats giving an average yield of 29 bu. per acre. The largest yield was 35.4 bu. per acre. With one exception, no plat gave less than 22 bu. per acre. Twenty-two plats gave yields of over 30 bu. per acre each, only 6 less than 25 bu. each. The wheat was all of inferior quality as judged by appearance as well as weight, that from no plat exceeding 58 Ib. per bu. The weight of these varieties, as grown at the Ohio and Indiana stations, averaged somewhat higher, but was less than the weights in other years. 1892.] WHEAT EXPERIMENTS, 1891-2. 113 Twenty-five plats of bearded wheat gave an average yield of 30.8 bu. an acre; 28 plats of bald wheat, an average of 27.5 bu. Six varieties were classed as white wheat. These gave an average yield of 25.8 bu. an acre, the largest yield being 30.3 bu. Of the white bald varieties, golden prolific gave 30 bu. and of the white bearded, Democrat gave the same yield. Of the red bearded varieties, the following gave yields of 30 bu. or more an acre, averaging over 33 bu. : Hindustan, 35.4; Diehl Mediterranean, 35.1; Deitz, 34.5; Tuscan Island, 34.1; Lehigh, 34.4; Crate, 33.7; Tasmania, red, 33.4; velvet chaff, 33.4; Nigger, 31.6; golden cross, 32.2; new longberry Wabash, 30.7, and Lebanon, 30.6. Of the red bald varieties, Poole, Currell's prolific, longberry, and improved rice gave yields of 30 to 32 bu. an acre. Four mixtures designated in the table (p. 118) as #, b, c, and ?, were made of varieties which, in appearance and in description of other characteristics, seemed much alike. These mixtures were composed of equal parts of the following varieties: Mixture #, velvet chaff [Penquite's] Lehigh, Hindustan, Tasmanian red, Nigger, Diehl Mediterranean, Tuscanlsland, Miami Valley, long berry Wabash, bearded monarch, and Fairfield. Mixture b, Wyandot red, Poole, Witter, Sheriff, Hicks, Fultz, Currell's prolific, Oregon, long berry, and early ripe. Mixture c, Russian red, improved rice, extra early Oakley, and Crate. Mixture d, Deitz, Lebanon, and Theiss. In each case the yield of grain per acre from the mixture was greater than the average yield from the varieties composing it, and in all but one the pounds of straw and pounds per bushel were greater. The increased yields from the mixtures over the average yields from their components was 2.5, 2, 2.4, and 2.8 bushels per acre for mixtures #, b, c, and d, respectively. The results of tests of varieties for one year can not be considered at all conclusive. In view of the reasonably close agreement in behavior of varieties treated this year at this Station and at the Ohio Station (p. 116), where a number of the varieties have been grown for several years, the recommendations contained in the report of the Ohio Station for 1892 is given: "Judging from the experience of this and former years, we recommend the following sorts of wheat as probably the safest for general culture throughout Ohio: Valley, Fultz, velvet chaff [Pen- quite's] Egyptian, and Nigger. Diehl Mediterranean, under its various names, has given good yields on this farm and in favored localities, but cannot be recommended for general culture, and the same may be said of Martin's amber and its synonyms Landreth and silver chaff. Rudy, Deitz, Poole, Currejl's prolific, early red Clawson, Hicks, and Jones's winter fife, are worthy of further trial." BULLETIN NO. 22. WHEAT VARIETY TESTS, 1891-92.
