Abstract

During the rabi season of 2021, a field experiment was conducted in the North Western plains of Uttarakhand at Crop Research Centre, School of Agriculture, Uttaranchal University, Dehradun to examine the impact of integrated nutrient management (INM) on lentil growth, yield, and economics (Lens culinaris Medik.). The experiment was laid in Randomized Block Design with seven treatments i.e. T1 (Control, 100% RDF (Recommended Dose of Fertilizers), T2 (75 % NPK (Nitrogen, Phosphorus, Potassium) + 25 % FYM (Farm Yard Manure), T3 (50 % NPK + 50 % FYM), T4 (75 % NPK + 25 % Azotobacter), T5 (50 % NPK + 50 % Azotobacter), T6 (75 % NPK + 25 % (Vermicompost + Azotobacter)) & T7 (50 % NPK+ 50 % (Vermicompost + Azotobacter)). The treatments T7 with the combination of 50 per cent NPK and 50 per cent vermicompost plus Azotobacter showed maximum LAI (Leaf Area Index) (0.25), NAR (Net Assimilation Rate) (0.0020), chlorophyll content (3.05), dry matter (4.44 g), and protein content (26.99 %) in contrast to other six treatments.
