The present study was carried out to investigate the difference of absorption and translocation of Ni by radish grown for 45 days under factors such as the levels of Ni in soil, soil pH, competitive metal interactions, covering with soil, organic matter and lime. Germination rate of radish in soil treated by Ni 150 ㎎/㎏ was 40%. As soil pH was increased, the contents of Ni translocated to radish showed the negative correlation(shoot=-0.965^(**), root=-0.837^*). The Ni content in shot and root of radish grown under 50 ㎎/㎏ Ni treated soil were slowly decreased with iron levels increased. However Ni content in shoot and root of radish grown under 50 ㎎/㎏ Ni treated soil showed increasing trend with the increasing the zinc levels. As covering with soil, organic matter and lime were treated, Ni contents of shoot and rout in radishes were in the decreasing order of organic matter$gt;covering with soil$gt;lime.
