Abstract
A pot culture experiment was conducted on Phaseolus aureus, Spinacia oleracea and Ocimum sanctumto study the effect of two bio-fertilizers viz, and Annapurna and Navajeevan.Annapurna contains Azotobacter, Azospirillum, Neem, Phosphate solubilizing bacteria, Castor and Trichoderma. Navajeevan contains bio-extract, organic fertilizer, sea-weed amino acids. The endophytic nature of Azospirillumholds promise, as nitrogen fixed by these bacteria is more available to the plant than in the rhizosphere associations.Production of hormones by Azotobacter enhances growth. Trichoderma and Phosphate Solubilizing Bacteria solubilize phosphates, micronutrients, increases the number of deeproots, increasing the plant's ability to resistdrought.It also helps in bioremediation of soil from xenobiotics. The ability of microorganisms to fix atmospheric nitrogen and transform native soil nutrients like phosphorus, zinc, copper, iron and sulfur from the non-usable to usable form and decompose organic wastes which can be easily assimilatedresulted in enhanced growth and metabolism.The atomic absorption spectrum of the plant tissues at different time intervals exhibited an increase of micronutrients viz Zn, Fe, Mn and Cu. This study concludes that Annapurna biofertilizer enhanced germination, plant growth, shoot biomass and mineral nutrient content, food quality and sustaining environmental quality from the ecological and agricultural perspectives.
