Abstract
Root distribution pattern of walnut trees grafted on seedling ischolar_mainstock was studied on at three radial distances from tree trunk and soil depth. The length and mass of fine ischolar_mains (diameter less than 1mm) was maximum (2633.52 cm and 19.43 g, respectively) within the tree canopy i.e. at a distance 2/3rd from tree trunk to drip line. It was significantly low near the tree trunk and towards the drip line. The length and mass of the fine ischolar_mains was more in the surface layer (2498.65 cm and 14.22 g, respectively). As the soil depth increased the RLD and RMD of the fine ischolar_mains decreased significantly. RLD of thicker ischolar_mains was not significantly influenced by the radial distance from the tree trunk but the RMD decreased significantly from the tree trunk to the drip line. Thicker ischolar_mains were significantly more in the surface layer of the soil.
