Abstract
A field experiment was conducted during rabi 2022-23 to study the effect of Integrated Nutrient Management on physical and chemical properties of soil such as soil bulk density, maximum water holding capacity, pH, electrical conductivity, organic carbon, available major nutrients. The following parameters were investigated in an experiment comprising eleven treatments replicated thrice in randomized complete block design with quinoa. The results of the experiment suggested that soil physico-chemical properties like maximum water holding capacity, organic carbon had significantly influenced with the application of 50% nitrogen dose (ND) + 50% N through FYM + seed treatment (Azotobacter + PSB). Soil major nutrients like nitrogen, phosphorus and potassium had a higher significant effect with the application of 50% nitrogen dose (ND) + 50% N through vermicompost (VC) + seed treatment (Azotobacter + PSB) in comparison to application of 100% fertilizer dose. In the other hand, soil properties like bulk density, pH, electrical conductivity did not have a significant influence with the practice of Integrated Nutrient Management in quinoa.
