Response of Soybeans to Seed-Treatment with Gibberellin Under Simulated Commercial Conditions1

Synopsis: The response of soybeans to seed treatment with gibberellin was studied at eight locations from Winnipeg, Man., to Coahoma, Miss. Stands and yields were reduced by applications of either 2 or 8 g. potassium gibberellate per bushel of seed. While treated plants were taller in the seedling stage, at maturity the controls were more than 5 inches taller than treated plants in most cases, Maturity and oil and protein contents of the seed were not affected consistently by gibberellin treatment.

1 Contribution from the Crops and Agricultural Engineering Research Divisions, ARS, USDA (Publication No. 333 of the U. S. Regional Soybean Laboratory, Urbana, Ill.), the Illinois, Minnesota (Science Jour. Series 4103, Minn. Agr. Exp. Sta.), Mississippi (Publication No. 784, Miss. Agr. Exp. Sta.), North Carolina (Jour. Series 1048, N. C. Agr. Exp. Sta.), and South Carolina Agr. Exp. Stas., and the University of Manitoba. This study was supported in part by a grant .to the Illinois Agr. Exp. Sta. from Merck and Co., who also supplied the potassium salt of gibberellic acid. Chemical analyses were performed by F. I. Collins and O. A. Krober.
