| Abstract:
This study was conducted at the Cashew Research Station, Vellanikkara, to find out the comparative development of the root system in cashew air-layers and seedlings and also the canopy spread of cashew plants of different age groups and its correlation with root spread in laterito soil. There was no appreciable difference between the length and depth of roots of layers and seedlings. The canopy spread showed a positive correlation with root spread. This may be used in determining the zone of fertilizer application and spacing in cashew. There was no detectable difference in height, girth and spread of canopy of seedlings and air-layers. It was also found that in hard soils of 3–40 cm depth, the tap root grew only to the depth of the soil. Even in deeper soils, the tap root could not be distinguished from the root system of the layers. | |
