Effect of Integrated nutrient management on growth parameters of wheat (Triticum aestivum L.) in the Dehradun Region

A field experiment was conducted to evaluate the effect of integrated nutrient management (INM) on growth parameters of wheat (Triticum aestivum L.) in the Dehradun region during the Rabi season of 2024–25. The experiment comprised ten treatments involving varying levels of recommended doses of fertilizers (RDF) alone and in combination with biofertilizers (Azotobacter and Azospirillum) and organic manure (FYM). Growth parameters such as leaf area index (LAI), number of tillers per meter row, and plant height were measured at 30, 60, 90 days after sowing (DAS) and at harvest. The results showed that integrated application of 100% RDF with Azospirillum significantly enhanced all growth parameters compared to other treatments and control. At harvest, the highest LAI (4.49), number of tillers (40.2/m row), and plant height (32.3 cm) were recorded in 100% RDF + Azospirillum treatment. The study concludes that INM practices significantly improve the vegetative growth of wheat and may be adopted to ensure sustainable productivity in the Dehradun agro-ecological zone.
