Abstract
Soil and nutritional factors are known to exert considerable influence on the development, spread as well as the intensity of plant diseases, particularly when the associated pathogen is weak. The coconut palm, though appears to be sturdy, is susceptible to a variety of diseases. Most of the important diseases of the palm are generally found to occur on all soil types. However, the disease appear in a more acute form under unfavourable soil/nutritional environments. Some diseases like bud rot and leaf rot are known to be caused by pathogens; some like the tapering stem or pencil point condition are believed to be due to unsuitable soil conditions while others like the stem bleeding are known to be associated with the infestation by pathogens predisposed by unfavourable soil and nutritional factors. Certain disorders like the crown choke are caused purely by nutrient deficiency. The nutritional problems and their management for some of the diseases and disorders of the palm are reviewed and discussed.
