A direct relationship was found between N-deficiency and frost damage to avocado trees. Lack of N resulted in typical N-deficiency symptoms expressed by restricted growth, pale small-sized leaves, and early leaf shedding; in addition the total number of fruits and fruit size were significantly reduced. Gradual increase in N level was followed by gradual decrease in frost damage. Reduced N fertilization resulted in reduced N levels in the leaves (below the critical levels) and fruits. The frost damaged fruit was not suitable for marketing. © 1987, Taylor & Francis Group, LLC. All rights reserved.
