Abstract

The study examined the productivity of wheat under integrated nutrient management employing inorganic, organic and bio-fertilizers over the course of two consecutive Rabi seasons in 2022-2023 and 2023-2024. During the Rabi season, the experiment was planned to use a Randomized Complete Block Design (RCBD) for wheat “HD 2967” (Wheat variety) was planted during November with twelve treatments. These included: T1 - absolute control (no fertilizer), T2 - 100 % recommended dose of fertilizers (RDF) through chemical sources and T3 to T12 - combinations of RDF (100 %, 75 %, or 50 %) with vermicompost (VC), poultry manure (PM) and biofertilizers (Azotobacter, PSB, KMB, ZSB, or NPK consortia). Pooled data indicated application of T9-75 % RDF + PM @ 1 t/ha + Azotobacter + PSB +KMB + ZSB resulted in highest plant height (98.26 cm), leaf area index (LAI) (4.72), dry matter (m-2) (1198.76 g m-2), number of spike (m-2) (307), spike length (10.51 cm), test weight (40.15 g), number of grains spike-1 (46.52), grain yield (5.39 t ha-1), straw yield (12.81 t ha-1) and harvest index (42.14 %).
