Total nitrogen, total protein, and individual free amino acids were compared in peanut leaves ( Arachis hypogaea L.) grown with two levels of boron. The boron‐deficient treatment decreased the fresh and dry weight of the plants compared to that of the boron‐sufficient treatment. On a per cell (rag DNA) basis, however, total amino acids and nitrogen increased, but protein remained unchanged in boron‐deficient leaves. The increase in amino acids was restricted to arginine, aspartate, glutamate, proline and serine. It was concluded that the increase in level of amino acids can be partially or perhaps completely accounted for by the excess nitrogen found in the leaves of the boron deficient plants.
