Abstract: The experiments were conducted during the Rabi seasons of 2014-15 and 2015-16 at Students’ Instructional Farm of C.S. Azad University of Agriculture and Technology, Kanpur with the objective to assess the effect of micronutrients, FYM and biofertilizers to improve root vigour, yield attributes and yield of wheat under irrigated conditions. The treatments consisted of superimposed dose of sulphur (25.0 kg.ha^-1), zinc (5.0 kg ha^-1), boron (1.0 kgha^-1), Iron (5.0 kg ha^-1), FYM (10 t ha^-1), Azotobacter and PSB (200g 10 kg^-1 of seed) as individually and in combination along with NPK doses compared with only NPK doses (control treatment), were laid out in Randomized Block Design and replicated three times. The response of above nutrient levels was analyzed on growth parameters, yield attributes and yield as well as economics of normal sown wheat variety Mahi (K-402). The superimposition of micro nutrients and microbial inoculants over NPK doses in different treatments exhibited significant response in terms of increasing root length (25% to 40%), root fresh weight (21% to 34%), effective tillers (25% to 38%), ear length (9% to 20%), grains ear^-1 (15% to 36%) grain yield (26% to 34%) compared to control treatment. The combined doses of NPK+FYM+S+Zn+B+Fe recorded highest grain yield (47.50q ha^-1 and 53.05 q ha^-1), gross income (Rs. 90325 ha^-1 and Rs. 103734 ha^-1) and net income (Rs. 46866 ha^-1 and Rs. 58088 ha^-1) during 2014-15 and 2015-16, respectively.
