Abstract

The tall variety (Var. typica) of the coconut palm, which lives even up to 80 or 90 years, is the one that is most extensively cultivated on a plantation scale in all the coconut tracts of the world. The age at which the palms come into bearing and their performance are highly variable and are dependent on the soil and climatic conditions and methods of management. In Kerala, the South-West Coast of India, since fresh area is not available for planting, new plantings taken up are all of underplanting nature with the result that the growth and performance of the seedlings under-planted are affected by the root and shade effects of the neighbouring palms. In this paper the results of a study made on the yield variation of under planted coconut palms of West Coast Tall variety, the time they had taken to attain their full bearing stage, the period taken to attain regularity in yield and the relationship of yield with the age and growth characters of the palms are presented and discussed.
