Abstract:
A field experiment was conducted at the Common Effluent Treatment Plant (CETP), Dindigul, Tamil Nadu during kharif 2011-12 to study the effect of treated tannery effluent with domestic wastewater irrigation and amendments on cotton yield, nutrient uptake, exchangeable soil anions, cations and exchangeable sodium percentage (ESP). Field experiment was laid out in factorial randomized block design with four replications. The results revealed that the mixing proportion of 25% treated tannery effluent (TTE) + 75% domestic wastewater (DWW) recorded higher seed cotton yield and nutrient uptake compared to other mixing proportions. The exchangeable Ca, Mg, Na, ESP, chloride and sulphate were higher under 100% TTE and lesser with normal water irrigation, whereas mixing ratio of 1:3 recorded lesser values than the other mixing ratios. With regard to amendments, application of gypsum showed better response than VAM and control. Among the mixing proportion of irrigation source and  amendments, application of 25% TTE + 75% DWW with gypsum registered lesser yield reduction compared to normal water irrigation with Gypsum
