Field experiments were conducted in orchard of BTC College of Agriculture Research Station Sarkanda, Bilaspur (IGKV) (Chhattisgarh), India, in rainy and winter season of 2018-19, with aim to test the plant growth potential of different indigenous bio-inoculants (Azospirillum, Pseudomonas spp. and Trichoderma spp.) on air layering of guava. Treatment include bio-inoculants alone or different combination viz. Azospirillum + Pseudomonas spp., Azospirillum, Trichoderma spp., Pseudomonas spp., Trichoderma viride + Azospirillum and Trichoderma harzianum + Pseudomonas etc. Results indicate that rooting and growth of air layers with different treatments alone or in combination i.e. Azospirillum + Pseudomonas spp., Azospirillum + Trichoderma spp., Trichoderma viride + Pseudomonas and Trichoderma harzianum + Pseudomonas were effective in promoting rooting in air layers and plant growth after transplanting.
