A study was carried out to see the effect of VAM, Rhizobium and inorganic fertilizers, alone and in combination, on plant growth in Dalbergia sissoo. Nine combinations comprising three levels of nitrogen and three levels of phosphorus were main plot treatments and four biofertilizers levels (No inoculation, VAM, Rhizobium) served as sub plot treatments. Significantly higher seedling length and diameter were recorded in dually inoculated plants than in VAM or Rhizobium inoculation alone. Nitrogen x phosphorus, phosphorus x bioferrtilizer and nitrogen x phosphorus x biofertilizer interactions also resulted in significant increased plant growth. Among all treatment combinations, dual inoculation of VAM + Rhizobium supplemented with 30kg Nha-1 and 75kg P2O5 ha-1 produced maximum seedling length and diameter. Desirable plantable size for field planting was achieved within six months after sowing (by the end September in the same season) in treatment combinations N30P75B (VAM + Rhizobium), N30P150B (VAM + Rhizobium) and N60P150B0 (No biofertilizer inoculation) thus saving resources I terms of time, space and money.
