(2) The symptoms exhibited by palms affected by root disease appear to have resemblance to those generally attributed to a deficiency of potassium. (3) Lack of accumulation of potassium in the leaf tissues of diseased palms as evidenced by leaf analysis, tends to give support to the conclusions mentioned earlier. (4) Pot culture and field trials are considered necessary before these conclusions can be considered as final- These trials are in progress.enArticle
