Effect of Potassium and Nitrogen on the Free Amino Acid Content of Corn Plants1
- Allen V. Barker and
- Richard Bradfield2
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.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
