Superimposition effect of micronutrients, organic manure and microbial inoculants over NPK does on wheat (Triticum aestivum L.)

Abstract

The present study was 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 find out suitable superimposed nutritional doses to improve production, productivity and economics of wheat under irrigated conditions. The treatments consisted of superimposed does of Sulphur (25.0 kg.ha), Zinc (2.0 kg/ha), Boron (1.0 kg/ha), Iron (5.0 kg/ha), FYM (5 t/ha), Azotobacter and PSB 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 fertility 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 grain yield from 11.94 to 26.10% compared to control treatment. The combined doses of NPK+FYM+S+Zn+B+Fe recorded highest grain yield (47.50q/ha and 53.05 q/ha), gross income (Rs. 90325/ha and Rs. 103734/ha) and Net income (Rs. 46866/ha and Rs. 58088/ha) during 2014-15 and 2015-16, respectively.
