Abstract:

The field experiments were conducted at Nematology field, ICR Farm, AAU., Jorhat during 2016 and 2017 to know the efficacy of bioagent, P. fluorescens and biofertilizer, Azotobacter sp. for that P. fluorescens and Azotobacter sp. were enriched in the substrates like farmyard manure, vermicompost and enriched compost. After enrichment of P. fluorescens and Azotobacter sp. were applied singly and in combination at the rate of 1% per hectare (ha). These treatments were compared with untreated control. It was recorded that the combined application of P. fluorescens and Azotobacter sp. found to be the best than individual application of P. fluorescens and Azotobacter sp. in all the tested substrates. However, among the tested substrates, the enriched compost found to be the best in single as well as in the combined application of P. fluorescens and Azotobacter sp. The pooled data showed that combined application of P. fluorescens and Azotobacter sp. enriched with enriched compost @ 1%/ha not only an improved the soil organic carbon, soil microbial biomass carbon content in the soil but also either maximizes the plant growth parameters like shoot height (cm), fresh and dry shoot weight (gm), root length (cm), fresh and dry root weight (gm), number of nodules per root system of black gram or minimizes the nematode infection i.e. number of galls and egg masses per root system of black gram and nematode population in the soil, as a result, increases the yield of black gram than rest of the treatments under field condition during 2016 and 2017.
