Abstract:
Bio-inoculants have been used for enhancing plant growth in fruits crops even in nutrient-limited soils. The present experiment was carried down to evaluate the effect of bio-inoculants such as Pseudomonas species + Ochrobactrum anthropi (DPC12+DPC9) and Pseudomonas fluorescens + Pseudomonas palluoniana (DPB15+DPB16) on Pant lemon-1, Kinnow and Grapefruit. All the treatments tested significantly increased survival percentages as well as root fresh and dry weight compared to the control. The best results were obtained from treatment of air layers with Pseudomonas species + Ochrobactrum anthropi (DPC12+DPC9) in Pant Lemon -1, followed by Kinnow and grapefruit. Hence, this treatment can be recommended for improving the propagation of Pant Lemon -1, Kinnow and grapefruit through air layering.
