Abstract

Nutrient imbalance and over-reliance on chemical fertilisers remain major constraints to sustaining wheat productivity and grain quality. To address this issue, a two-year field experiment was conducted during the rabi seasons of 2021–22 and 2022–23 at the Student Instructional Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh. The study evaluated the effects of integrated nutrient sources on soil physico-chemical properties and wheat grain quality. The experimental design followed a randomised block layout, incorporating 11 distinct treatments replicated thrice. The integrated treatment comprising 100 % recommended nitrogen-phosphorous-potassium (NPK) + sulphur (S)                      (40 kg ha-1), zinc (Zn) (5 kg ha-1), iron (Fe) (10 kg ha-1), Azotobacter + phosphate-solubilising bacteria (PSB) + farmyard manure (FYM) (5 t ha-1) (T10) significantly improved grain yield, soil organic carbon and nutrient availability. Grain quality parameters, including protein, lysine and methionine contents, were also significantly enhanced under integrated nutrient management across both years.
