Phytoremediation Efficiency of Sunflower Crop with Textile and Dye Industry Liquid and Solid waste and Amendments on Phosphorus Status of Polluted Soil Habitat

摘要

Gypsum, pressmud, farm yard manure, ETP sludge were tried to ameliorate the textile and dye effluent polluted soil habitat,using sunflower (CO4) as a test crop. The sludge along with effluent irrigation added considerable quantities of cations(calcium, magnesium and sodium) to the soil system. Application of pressmud @ 5 t ha~(-1) along with 100 per cent GR + NPK reduced the soil ESP by 44.96 per cent. The heavy metal content were also reduced due to addition of pressmud. Higher microbial population was also observed under effluent irrigation than well water. Application of 100 per cent GR + pressmud @ 5 t ha~(-1) + NPK under effluent irrigation increased the crop growth, yield attributes (head diameter, head weight, seed test weight) and yield of sunflower in effluent polluted soil habitat. The yield under pressmud amended plots was 36 percent higher over control. Reclamation and restoration of textile dye effluent polluted soil habitat is possible by leaching the soil with 100 per cent GR followed by application of pressmud @ 5 t ha-1 and recommended NPK.
