Abstract
A study on “Effect of organic and inorganic amendments on abatement of industrially polluted soils grown with castor crop” was conducted at College of Agriculture, Rajendranagar, Hyderabad for evaluating the amendments to abate the polluted soils. The results revealed that in Isnapur soils, highest castor dry matter yield was observed in treatment applied with the application of RDF (NPK)+5t VC ha-1 (41.80 g pot-1), whereas in Katedan soils, highest dry matter was observed with N and K (RDF)+60 kg P2O5 ha-1. Among the treatments highest N and K contents were observed in castor crop grown on Isnapur polluted soil with the treatment of RDF (NPK)+5 t VC ha-1, whereas P content was highest in treatment with the application of 100 kg P2O5 ha-1 along with N and K as RDF. The Cd, Ni, Cr and Pb contents were decreased with the application of phosphorus, vermicompost and CaCO3. Application of 5% CaCO3 along with RDF showed significant reduction in contents over other treatments.
