Online published on 23 March, 2021. Abstract To understand the effects of integrated nutrient management on enzymatic activity and population of micro-flora, a field experiment was conducted in Udaipur, Rajasthan, India. Biological analysis revealed that maximum dehydrogenase activity and micro-flora (bacteria and fungi) population recorded with the sole application of poultry manure @ 5 t ha−1, 75% of recommended dose of fertilizers (RDF) and combined application of Azotobacter + phosphate solubilizing bacteria (PSB) over rest of treatments. These results imply that organic manures as well as increasing level of nutrients trigger the dehydrogenase activity and micro-flora populations. Overall, results would indicate that application of organic manures, inorganic fertilizers and biofertilizers affects soil biological properties. Top Keywords Dehydrogenase activity, Bacteria population, Fungi population, Integrated nutrient management. Top |
