Investigatons were carried out to study the effect of tannery effluent on soil properties and growth of finger millet in pot culture. Amendments like gypsum, pressmud, FYM, rice husk ash, cement dust and composted coirpith were tested in combination with raw and diluted effluent. The effluent irrigation increased the bulk density, pH, EC and organic carbon content of soil. Raw effluent reduced the N,P and K uptake but the diluted effluent increased it. Among the amendments, gypsum, pressmud and composted coirpith recorded higher uptake of N, P and K respectively. The grain and straw yields were very much reduced due to effluent irrigation. The diluted effluent irrigation along with composted coirpith recorded higher yield.
