Abstract
A study on tbe life history of the tall coconut on the West Coast of India from the seednut the adult palm stage under regular planting indicated that (1) there is a setback in the growth of the seedling in the nursery at the fifth h from the time of germination which is attributed to the complete utilisation of the endosperm the seedling and a gradual change over to full dependence on photosynthesis for nutrition and (2) there is again another setback in the growth of the ling after transplanting which is attributed to transplanting shock due to the damage to the and disturbance caused during transplanting. These setbacks in growth in the seedling stages in the nursery as well as in the field lead to delay in flowering and attaining the stabilised yield period* INTRODUCTION The palm attains yield stability in the 19th year after flowering. The maximum yield period of the palm is during 19th to 41st year after flowering which is followed by the steady lower yield period of about 20 years afterwhich there is slow decline in yield. The growth of the palm declines as the palm advances in age. The study has indicated the need to avert the setbacks in growth in the early stages of its life cycle by either early transplanting in areas wherever possible or by paying proper attention to timely irrigation and fertilisation of the seedlings in the nursery as well as in the field' so that the time lag between planting and flowering is reduced to the minimum which will bring early benefit to the planters.
