Seedlings of teak were planted under different salinity levels viz., normal soil (<4 ECe soil), saline soil (4-8 Ece) and highly saline soil (8-12 ECe) and seedlings were inoculated with Azetobactor + vesicular-arbuscular mycorrhizal (VAM) fungi, Azospirillium + vesiculararbuscular mycorrhizal (VAM) fungi and combination of all three. Experiment repeated for two years and data recorded at the end of each experiment on nutrient satus of soil pH, ECe N, P, K, Ca, Mg, Na, micronutrient (Fe, Zn, Mn and Cu) and survival per cent of seedlings. Triple inoculation (Azetobactor+Azospirillium+VAM) significantly influenced on the nutrient status of soil and survival per cent of teak seedlings as compared to uninoculated seedlings under salt condition. Which was followed by dual inoculation of Azospirillium and VAM.

Abstract


Seedlings of teak were planted under different salinity levels viz., normal soil (<4 ECe soil), saline soil (4-8 Ece) and highly saline soil (8-12 ECe) and seedlings were inoculated with Azetobactor + vesicular-arbuscular mycorrhizal (VAM) fungi, Azospirillium + vesiculararbuscular mycorrhizal (VAM) fungi and combination of all three. Experiment repeated for two years and data recorded at the end of each experiment on nutrient satus of soil pH, ECe N, P, K, Ca, Mg, Na, micronutrient (Fe, Zn, Mn and Cu) and survival per cent of seedlings. Triple inoculation (Azetobactor+Azospirillium+VAM) significantly influenced on the nutrient status of soil and survival per cent of teak seedlings as compared to uninoculated seedlings under salt condition. Which was followed by dual inoculation of Azospirillium and VAM.
