Impact of Combining Microbial Enriched Organic Manures with Inorganic Nutrients on Physiological Characteristics and Productivity of Pearl Millet (Pennisetum glaucum L.)

The present investigation was undertaken to validate the integrated use of inorganic fertilizers and biofertilizers inoculated in organic manures on the physiological attributes and of pearl millet in the School of Agricultural Science, Karunya Institute of Technology and Sciences, Coimbatore, India. The experiment was laid out in Randomized Block Design (RBD) with three replications, during the rabi season of 2023-24. Results outlined that the integrated nutrient management practice of applying Azospirillum & PSB enriched vermicompost @ 6 t ha-1 + 100% Recommended dose of N, P2O5 & K2O has significantly increased the physiological attributes (leaf area index, crop growth rate, chlorophyll index), and yield (grain yield and stover yield) of pearl millet. This was statistically on par with the treatment Azospirillum & PSB enriched FYM @12.5 t ha-1 + 100% RDF dose of N, P2O5 & K2O.
