A field experiment was conducted during rabi seasons of 2021-22 and 2022-2023 at Research Farm, Department of Agronomy, College of Agriculture, JNKVV, Jabalpur (M.P.). The experiment was laid out in Split Plot Design with 20 treatment combinations were replicated thrice. Twenty treatment combinations consisted of five sources of nutrient (Control, Vermicompost @ 2 t ha -1, FYM @ 5 t ha -1, NPK (100% RDF) 20: 60: 20 N: P2O5:K2O kg ha-1 and Nano DAP (Seed treatment 5 ml kg-1 seed and foliar spray 0.4 % at 30 DAS), put under main plot and four bio-fertilizer (Control, Rhizobium 10 g kg-1, PSB 10 g kg-1 seed and Rhizobium+PSB (10 + 10 g kg-1 seed) allotted under sub plot. The study on impact of nutrient sources and bio-fertilizers on physico-chemical properties of soil. The results are revealed that application of vermicompost @ 2 t ha-1 found significantly improved porosity (reducing BD from 1.35 to 1.31 g cm-3) and water holding capacity 38.20-44.58%, organic carbon 0.59 to 0.65% as well as available status of major nutrients i.e., N, P & K. Whereas, the use of bio-fertilizer in combination with Rhizobium and PSB perform to increase the soil physical and chemical properties in respect of BD, WHC & OC as well as N & P status of soil.

Chickpea, Rhizobium, PSB, vermicompost, FYM, Nano DAP, water holding capacity and soil bulk density

Based on the foregoing discussion, it can be concluded that sources of nutrients and bio-fertilizers played an vital role in physico-chemical properties of soil. The soil bulk density and water holding capacity were significantly affected by sources of nutrients and bio-fertilizers. The combined application of enriched vermicompost @ 2 t ha-1 along with Rhizobium and PSB was recorded superior among all physico-chemical properties and followed by FYM @ 5 t ha-1 along with Rhizobium and PSB as compared to others nutrient sources.
