The present investigation is carried out to study the viability and shelf life of Rhizobium and Phosphorus Solubilizing Bacteria in the combined inoculations with either Trichoderma viride or Pseudomonas fluorescens on the biologically coated Pigeonpea seed. The effect of combined inoculation on the viability and shelf life of biofertilizers and seed quality parameters were studied at monthly intervals during storage period of six months. The results indicated that among adjuvants, seed inoculated with biofriendly polymer recorded more colony units and long shelf life than farmer practiced sugar syrup. At the end of six months storage period, both Rhizobium and Phosphorus Solubilizing Bacteria with biofriendly polymer recorded sufficient number of colony units on the surface of biologically coated pigeonpea seed. Both Rhizobium and PSB showed high colony counts with Trichoderma than with Pseudomonas and same trend was recorded throughout the storage period of six months. At the end of storage period, good seed germination and seedling vigour was recorded in the seeds that are co-inoculated with PSB and Pseudomonas than with Trichoderma and Rhizobium. This study reveals that the farmers can be supplied biologically coated seed in advance and the general practice of treating the seed a day prior to sowing can be avoided.
