Abstract

Low soil fertility is one of the bottlenecks to sustain agricultural production and productivity in India. Nutrient mining by intensive cropping systems and inadequate supply of nutrients have aggravated the situation. Integrated nutrient management (INM) options utilize available organic and inorganic nutrients for sustainable agricultural production and productivity. A field experiment was conducted during kharif at Fertilizer Research Station of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, India. The aim of this study was to see the effect of graded doses of nitrogen with and without Azotobacter inoculation on yield and nutrient uptake by maize crop. Grain yield increased with increasing levels of nitrogen, and maximum grain yield of 4.3 Mg/ha was obtained by use of 150 kg N/ ha with FYM @ 5 t/ha and Azotobacter inoculation. Significant uptake of nitrogen, phosphorus and potassium was recorded under application of 150 N kg/ha over the control. Protein content in maize grain increased significantly by conjoint use of organic manure and biofertilizers with each level of nitrogen application, over application of each nitrogen level alone.
