Abstract
An experiment was conducted to determine the effect of inorganic and biofertilizers, alone and in combination, on biomass production of Dalbergia sissoo seedlings. The treatments comprised of all possible thirty-six combinations of three levels of nitrogen, three levels of phosphorus and four biofertilizers levels. Dual inoculation with Rhizobium and VAM resulted in significantly higher fresh and dry weight of shoot and root as against single inoculation of Rhizobium or VAM and uninoculated control. Inoculation with Rhizobium or VAM alone resulted in higher shoot fresh weight and dry weight as compared to control. Biomass production was increased with application of nitrogen and phosphorus. Dual inoculation of Rhizobium + VAM combined with application of 30 kg ha-1 and 75 kg P2O5 ha-1 produced seedlings with approximately three times more shoot and root biomass than uninoculated and unfertilized control.
