Abstract : Soil dehydrogenase (14.2, 11.3 mg TPF g-1 day-1), alkaline phosphatase (109.5, 86.7 mg PNP g-1 soil h-1), acid phosphatase (69.7, 51.6 mg PNP g-1 soil h-1) and urease activity (60.4, 39.9 mg NH4 g-1 2 h-1) in chickpea at flowering and harvest with seed rate @ 105 kg ha-1. Among, nutrient management the corresponding activity (14.9, 11.7 mg TPF g-1 day-1), (120.7, 96.7 mg g PNP g-1 soil h-1), (70.5, 52.7 mg g PNP g-1 soil h-1) was higher with 75% RDF + microbial consortia (MC). Contrarily, urease activity (62.3, 38.7 mg g NH4 g-1 2 h-1), soil available soil nitrogen (181.3, 179.0 kg ha-1) and phosphorus (78.3, 76.5 kg ha-1) were higher under 125% RDF + MC. PCA indicated that among nutrient management, first principal component explained 71.37% variability to urease activity, available soil potassium and dehydrogenase activity and second component (22.34%) to available soil phosphorus and nitrogen. Among planting density, first component explained variability (66.87%) to acid phosphatase and second component (32.11%) to available phosphorus.
