Abstract: The practice of incorporating organic manures and fermented liquid biofertilizers of different origins and compositions can supply valuable nutrients to the soil. To ascertain the effect of fermented liquid organic nutrient formulations (FLONFs) on the rhizospheric microbial population, growth characteristics, nutritional status, and yield of brinjal, a field experiment was conducted in consecutive seasons in 2017 and 2018. Fermented liquid biofertilizers (panchagavya and jeevamrut) were prepared and applied along with organic manures to brinjal plants in ten treatment combinations in three replications. The treatment (T 4 ) involving the combined use of organics and FLONFs contributed significantly to the soil dehydrogenase enzyme activity (4.9 mg TPF h −1 g −1 soil), phosphatase enzyme activity (25.5 mmoles PNP h −1 g −1 soil), and urease enzyme activity (0.27 mg NH4 + g −1 soil). The mean bacterial count, fungal count, and actinomycete levels were 203.3 × 10 8 cfu g −1 , 4.34 × 10 3 cfu g −1 , and 3.41 × 10 2 cfu g −1 soil, respectively, along with a mean soil microbial biomass of carbon value of 66.1 mg g −1 soil. The brinjal yield was maximal under treatment T 4 with values of 389.2 q ha −1 and 153.7 q ha −1 for 2017 and 2018, respectively. As a result, for higher yields and soil longevity, the combination of organics and FLONFs can be advocated.
