The aim of the study was to investigate distribution, enrichment and accumulation of heavy metals in soil and Trigonella foenum-graecum (var. Pusa Early Bunching) after fertigation with paper mill effluent. Doses of paper mill effluent viz. 5%, 10%, 25%, 50%, 75 % and 100 % were used for fertigation of T. foenum-graecum along with bore well water (control). The results revealed that paper mill effluent had significant (P < 0.05) effect on EC, pH, OC, Na+, K+, Ca2+, Mg2+, Fe2+, TKN, 34PO , , Cd, Cr, Cu, Mn and Zn of the soil in both seasons. Insignificant (P> 0.05) changes in WHC and bulk density of the soil were observed after irrigation with paper mill effluent. The agronomical performance of T. foenum-graecum was increased from 5 % to 25 % concentration and decreased from 50 % to 100% concentration of paper mill effluent as compared to control in both seasons. The heavy metals concentration was in-creased in T. foenum-graecum from 5 % to 100 % concentrations of paper mill effluent in both seasons. Biochemical components like crude proteins, crude fiber and crude carbohydrates were found maximum with 25 % paper mill efflu
