Abstract

The present investigation was conducted to access the agro-potentiality of sugar mill effluent (SME) as fertigant, and an alternative of irrigation water. Fertigation response of 20, 40, 60, 80 and 100% of SME doses on Sorghum bicolor L., cv. CSH 9, in the rainy and summer seasons was investigated. The fertigant concentration produced significant (P<0.01) changes in EC, pH, OC, Na+, Ca2+, K+, Mg2+, TKN, PO43-, SO42-, Fe2+, Zn, Cd, Cu, Mn and Cr of the soil in both seasons. The agronomic performance of S. bicolor gradually increased from 20 to 40% concentration and decreased at 60 to 100% concentration of SME fertigation in both seasons compared to controls. The optimum growth of S. bicolor was recorded with 40% concentration of SME. The accumulation of heavy metals increased in soil and S. bicolor from 20% to 100% SME concentrations in both seasons. Biochemical components like crude proteins, crude fiber and crude carbohydrates were found maximum with 40% SME in both seasons. The contamination factor of various heavy metals was in order of Mn > Zn > Cu > Cr > Cd for soil and Cu > Mn > Zn > Cr > Cd for S. bicolor in both seasons after fertigation with SME.
