Abstract: Plant growth promoting bioinoculants have beneficial properties to increase plant growth. The present experiment was carried out at HRC, Patharchatta, Department of Horticulture, G.B. Pant University of Agriculture and Technology, Pantnagar to study the effect of bioinoculants on rooting of different citrus species. Citrus species viz., Pant lemon-1, kinnow and Grapefruit were selected for the experiment. PGPR species viz., Pseudomonas species, Ochrobactrum anthropi (DPC12+DPC9), Pseudomonas fluorescens and Pseudomonas palluoniana (DPB15+DPB16) were used in the study. They were applied in each air layer in all three citrus species under proposed treatments used for preparation of air layers. Among all citrus species, Pant lemon-1 recorded the minimum days taken to root initiation (25.66 days), maximum average number of roots (33.90), maximum average length of roots (7.66 cm), maximum fresh weight of root (3.26 g) and the maximum dry weight of root (0.97 g) as compared to Kinnow and Grapefruit.
