AbstractAbstract
[en] The techniques of soil and plant tagging with P32 and excavation method using 'pin-board' are compared for studying rooting pattern of groundnut variety of C 501. The isotope methods are more sensitive as they detect the presence of roots as far as 25-30 cm radial distance from plant at various soil depths but these roots cannot be found with excavation method, probably because they are lost during the washing process. The results from P32 soil tagging technique show that more than 75% of roots in this variety of groundnut are confined to a cylinder 30 cm in radius and 12.5 cm in depth. The plant tagging technique reveal that this zone represents 25 cm radial distance from plant and 22.5 cm depth from soil surface. (author)
