T soybean, like any ~ther crop which is being produced in its border area of adaptation~ presents many special problems, the answers to which must be sought in the area where the production of the crop is being attempted. This paper is the report of a study of the effect of space and arrangement of plants on the production of soybeans in the northeastern range of their production. This is only one ̄ of many problems which might be studied with interest and profit. Further information is needed on varieties, inoculation, fertilization, cultivation, the effect of length of day, and utilization. Accepting the recommendations of the corn belt investigators as to the best method of distribution of the seed of soybeans for maximum production, cultivated rows 36 inches apart were used in the ̄ beginning as a standard method in the experimental work at the New York State College of Agriculture. By i93° the width of row had been reduced to 28 inches, to the advantage of increased production. A solid drill varietM test was established in i93 ~ to include the more promising varieties for grain. Both cultivated rows, 28 inches apart, and solid drills, with rows 8 inches apart, have been used in varietal trials continuously since that date. Table i gives the results in bushels per acre for three of the several strains in these tests.
