Abstract: The field experiment was conducted A pot experiment was carried out at the Department of Soil Science and Agricultural Chemistry, BTC College of Agriculture and research Station, Bilaspur, during Kharif season 2015-16. On the basis of 1st season results farmer’s field demonstration was also carried out at field of farmer’s (from where bulk of soils were collected for pot experiment) during Rabi season 2015-16. The soils used for pot experiment were two type i. e. Inceptisol and Vertisol. Both the soils were collected from two different locations of Bilaspur district. Collected soils were air dried and filled in cemented pots. 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 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 Inceptisol were kept keeping the concept of soil reaction. After addition of all treatments, rice (MTU-1010) was transplanted in three hills/pot with 2-3 seedlings in each hill. In eleven treatments. The highest P (0.24%), Ca (0.21%), Mg (0.16%) and S (0.16%), Mn (54.32 mg kg^-1), Zn (27.87 mg kg^-1) and B (12.87mg kg^-1) contents in rice grain were recorded in the treatment that received all the nutrients (T₁) while, the highest Fe (38.290 mg kg^-1), was in treatment T₁₀ B omitted were recorded in treatment T₁ which received all nutrients content in rice grain under Vertisol. The highest P (0.24%), Ca (0.21%), Mg (0.16%) and S (0.16%) contents in rice grain were recorded in the treatment that received all the nutrients (T₁) and The highest value of Zn (31.38 mg kg^-1) and B (3.86 mg kg^-1) content were recorded in treatment received all nutrients (T₁). Omission of Zn (T₉) and B (T₁₀) only, were reduced the Zn and B content in rice straw.
