A field experiment was conducted on the Vertisol at Research farm, Dept. of Soil Science and Agriculture Chemistry, College of Agriculture, Indira Gandhi Krishi Vishwavidhyalaya, Raipur, Chhattisgarh. The sustainable yield of wheat was higher in different treatment combinations over control as observed during assessment of sustainable yield index (SYI) at five year interval i.e. 2003-04, 2008-09, 20013-14 and 2018-19 as well as after continuous 20 years (1999-2019) of wheat yield. The sustainability in yield was increased with graded levels of balanced application of fertilizers from 50 to 150 % NPK. The balanced inorganic fertilization gave higher SYI than control. If graded levels of fertilizers with organic manure and biofertilizer (FYM, GM and BGA) were applied in kharif it appeared that application of higher levels in wheat had increased the SYI.
