Effect of Different Amendments and Inorganic Nutrient Management Approaches in Correcting Sodicity under Paddy Eco System

Agricultural production in sodic soil may be hindered by its unfavorable physicochemical properties. In order to find effective measure improve the health of and make it favourable for crop production, a field experiment was conducted at ZARS VC Farm Mandya study effect different amendments on properties soil. The laid under split plot design with inorganic nutrient management viz., RDF, SSNM STCR as main treatments such press mud, gypsum Mangala setright, (a commercial conditioner containing 15% calcium 3% magnesium 5% sulphur) sub treatments. Results revealed that application significantly reduced pH 8.5 from 8.96 initial which par setright 600kg/ha (8.68) mud (8.69). Whereas exchangeable sodium ESP due 400 kg/ha (1.78 cmol/kg 6.52 respectively) pressmud 100% GR (1.85 7.03) compared control (3.69 13.72 Thus Setright 400kg/ha or are more beneficial rectifying sodicity
