Effects of soil amendments with bio-inoculants on biomass production of Flemingia semialata seedlings

Multi-location trials of containerised seedlings with of Flemingia semialata Roxb. developed in the nurseries of Department of forestry, Mizoram University and College of Forestry, OUAT to study the effect of bio-inoculants on root and shoot fresh biomass at various stages. Both the locations recorded similar trend, thus pooled together. At one month age though bio-inoculation had no remarkable response to root fresh biomass but had response to shoot fresh biomass, the latter acquired maximum value (0.185 g) in Rhizobium + Mycorrhizae with low fertilisation (125 mg N₂, 125 mg P₂O₅ and 125 mg K₂O per polypot). At 2, 4 and 6 months both the parameters had significant response to bio-inoculation. At 2 months Rhizobium + Mycorrhizae with medium fertilisation (250 mg N₂, 250 mg P₂O₅ and 125 mg K₂O per pot) recorded maximum root fresh biomass (0.214 g) and shoot fresh biomass (0.421 g) accumulation. Of course, at 4 months highest fresh root biomass (2.388 g) was with Rhizobium + Mycorrhizae with high fertilisation (375 mg N₂, 250 mg P₂O₅ and 250 mg K₂O per polypot) the treatment Rhizobium + Mycorrhizae with low fertilisation gave highest fresh biomass accumulation of root at 6 months (6.452 g) and of shoot at both 4 months (7.583 g) and 6 months (27.325 g).
