Experiment on effect of liquid bioinoculants on biomass production of Annual moringa (Moringa oleifera Lam.) var. PKM – 1 was carried out during October 2016- May 2017 at Horticultural College and Research Institute, Tamil Nadu Agricultural University, Periyakulam. Liquid biofertilizers viz., Azospirillum brasilense (Azos), Bacillus megaterium (PSB), Bacillus mucilagenosus (KSB) and Methylobacterium extorquens (Pink Pigmented Facultative Methylotrophs -PPFM) as bioinoculants along with graded level of recommended dose of inorganic fertilizers (75%, 100% and 125% of RDF) were used in the experiment. Inorganic water soluble fertilizers in four stages in all the treatments on 20 DAS, 50 DAS, 80 DAS and 110 DAS, the liquid bio inoculants Azospirillum, PSB and KSB were 15 days after the application of inorganic fertilizers were applied through drip irrigation. PPFM is applied through foliar application as per the treatment along with other microbial inoculants. Plant growth and biomass yield parameters were recorded in periodic intervals and the data collected were statistically analyzed. The results revealed highest plant height, number of branches per plant, number of leaves per plant, leaf area, chlorophyll content, chlorophyll stability index was observed in the plants treated with 125 % of RDF along with all microbial inoculants used for the study. Besides the same treatment combination also recorded fresh and dry leaf biomass in all the harvests done during the experiment.
