Abstract: A pot culture experiment was conducted in the Department of Soil Science and Agricultural Chemistry, BTC College of Agriculture and research Station, Bilaspur, during Kharif season 2017-18. The treatments constituted with application of all nutrients applied at optimum level known as All (SSNM dose) while in others, one of the nutrient elements from all the nutrient treatments (All) was omitted. There were eleven treatments for each type of soil and three replications with CRD (completely randomized design). All treatments were common for both the soils except omission of Fe and Mn in case of Vertisol and omission of Ca and Mg in case of Inseptisol were kept keeping the concept of soil reaction. After addition of all treatments, rice (IGKV R-1) was transplanted in three hills/pot with 2 to 3 seedlings in each hill.The soil reaction (pH) of the Vertisol was at 7.6 and that of Inceptisol exhibited 6.9. Both the soils were low in, organic C, available N, S, and available P, high status in available K, exchangeable Ca and Mg. The micronutrient status of the soils were above critical level specially high status in Fe, Mn and Cu level except B and Zn in Vertisol and Inceptisol.
