Effect of Potassium and Nitrogen on the Free Amino Acid Content of Corn Plants1

Allen V. Barker and Richard Bradfield2

Synopsis: Growth was limited by deficient and excessive quantities of both N and K. Nitrogen deficiencies and excesses gave the greatest reductions in yields. Generally, growth was greater when a large proportion of the N was supplied as NH4+. Asparagine was the predominant amino acid in the plants. The content of asparagine and other free amino acids was increased by higher levels of N nutrition and higher proportions of NH4+-N within any given N level. It was decreased by higher levels of K.

1 Contribution from the Department of Agronomy, Cornell University Agricultural Experiment Station, Ithaca, N. Y., as Agronomy Paper No. 612. A portion of a thesis submitted by the senior author in partial fulfillment of requirements for the Ph.D. degree at Cornell University.

2 Formerly Graduate Student and Professor of Soil Technology (now Post-doctoral Assistant, North Carolina State College, and Professor of Agronomy, Emeritus, Cornell University).

Received for publication January 29, 1963.
