The analysis results showed that composting, experimental soil and Brassica juncea (L.) were steady accumulated lead In that lead concentration in Brassica juncea (L.) was from 0.0311 mg/kg to 0.3317 mg/kg It is lower than the allowed limit in fresh vegetable of the Health Ministry (in 1998) The rate of lead concentration in Brassica juncea (L.) infected from experimental soil is 0.254% (NT1 treatment) The rate of lead concentration in Brassica juncea (L.) in NT2, NT3 and NT4 treatments is 0.116%, 0.139% and 3.544% respectively In NT3 treatment added 400 grams composting in the basal fertilizing period is not only the highest yield but also low lead concentration in Brassica juncea (L) GVHD: ThS Bui ThiMaiPhung Khda luan tot nghiep rftii hocSVTH: Nguyen Ha Duyin TOM TAT Thi nghiem
