Abstract: The present investigation was carried out to study the effect of biological seed coating with bioprotectants and biofertilizers using polymer on the seed quality and storability of pigeonpea. The pigeonpea seed was coated with Trichoderma viride and Pseudomonas fluorescens with combinations of Rhizobium or Phosphorus Solubilizing Bacteria using two adjuvants like polymer and sugar syrup. The seedling vigour parameters were studied at monthly intervals during storage period of six months. Six months after treatment, seed combinely inoculated with Trichoderma and Rhizobium (1314 and 69, respectively for SVI1 and as SVI 2 and Pseudomonas and Phosphorus Solubilizing Bacteria 1178 and 69, respectively for SVI1 and as SVI 2 showed high seedling vigour. Among adjuvants, biopolymer recorded good vigour compared to farmer practice of sugar syrup. Seed combinely coated with bioprotectants and biofertilizers recorded more vigour compared to single organism inoculation. The results of the study thus indicated the possibility of coating seed with biological agents with effective biofriendly polymer as an adjuvant immediately after processing before packaging without affecting the seed quality. Thus, the farmers can be supplied biologically coated seed in advance and the general practice of treating the seed one day prior to sowing can be avoided.
