NEW JERSEY
Dr. E. B. Voorhees, Director New Jersey experiment station.—The farmers of the state have manifested much interest in the growing of alfalfa, and many experimental plots have been seeded in the past two or three years. In order to obtain accurate information as to the methods employed, and the results obtained, a circular letter was sent out during the past summer to 140 growers. Detailed replies were obtained from 101 growers. Of these there were 57 distributed over 15 counties, which showed the successful establishment of the crop. The soils upon which these successful crops are growing vary widely, both in their physical and chemical character, ranging from a light, sandy loam, with sandy subsoil, to a medium heavy clay, with compact clay subsoil, which indicates clearly that success does not depend so much upon the character of the soil as upon the methods of seeding, fertilization and after-treatment, though the most successful stands were, as a rule, obtained upon sandy soils, overlying a reasonably open subsoil. Twenty-seven growers had a more or less satisfactory experience, while 17 were absolute failures. A study of the reports of failures shows that in most instances they were due to lack of observation of the methods recommended for the seeding and care of the crop, which experience at the station showed to be essential for success. In most cases the land was imperfectly prepared; in many an insufficient amount of fertilizer or manure was applied. In many cases, too little seed was used; in others the date of seeding was contrary to all recommendations, or the crop was not clipped often, and thus choked out by weeds. In many instances, where lime had not been used for many years, none was applied at the time of seeding. In the case of those having more or less success, the recommendations were not fully observed or soil conditions were imperfect.
D. C. Lewis of Middlesex county, in the summer of 1903 seeded about 11⁄4 acres with alfalfa, observing closely all of the recommendations of the experiment station in reference to seeding, but did not inoculate the soil. The seed germinated well, and the crop grew nicely during the fall, but entirely disappeared later. In 1904, the same area, after an oat crop was grown, was seeded again, on August 10. The soil is a clay loam, with a clay subsoil, and in a good state of fertility. The land had been previously in grass and corn. The corn was manured and the alfalfa area well limed previous to seeding in 1903. The seed was at the rate of about 25 pounds, and at time of seeding 800 pounds of Mapes’ fertilizer and an extra bag of high-grade sulphate of potash were applied, and the field was inoculated with about 300 pounds of soil, taken from the old alfalfa patch at the experiment station. The seed germinated well, and made a rapid and large fall growth and passed the winter successfully. The yield per acre was about three tons of hay for the first cutting. This experiment is strikingly suggestive in showing the importance of soil inoculation, for while inoculation is not apparently essential in all cases, it would seem that where soils have not been heavily manured that this point should be carefully observed.
J. P. Nelson of Monmouth county has had a very successful experience in the growth of alfalfa, since he has observed all of the recommendations made as to methods of seeding and after-treatment. The following is a description of his method and the results obtained from a seeding made August 10, 1904. The surface soil is a medium clay loam, underlaid with a gravelly clay subsoil. The crops preceding were grass and corn, and the manures used were barnyard manure and 600 pounds per acre of ground bone. The corn preceding the alfalfa was limed at the rate of 1,000 pounds per acre, and 1,400 pounds per acre were applied just previous to the seeding of alfalfa. Thirty pounds of seed were used per acre, and lightly harrowed in and the land rolled. The germination and early growth were good, and the first crop was harvested June 1, 1905. The yield was two big, two-horse loads of cured hay per acre.
E. T. Gill of Camden county has a sandy loam, underlaid by a subsoil varying from sand to clay. He has an area of 24 acres, ranging from two to six years in age. The first seeding of about two acres is still growing profitable crops, though not uniform in stand. The later seedings show an excellent stand and large and profitable crops are annually harvested. Usually four cuts are made each year, which are used both for soiling and for hay, with splendid results. The practice on this farm is to top-dress with manure during the winter at the rate of about eight tons per acre. Mr. Gill’s experience leads him to believe that the stand is often injured, particularly during the first year, by allowing the crop to reach too great maturity and then cutting when the plants are just beginning to bloom, and leaving a stubble of at least three inches. Mr. Gill did not inoculate the seed or soil at his first seeding, but did follow this practice with recent seedings, and believes it to be a wise precaution, especially on soils that have not been previously heavily manured.
