Abstract:
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 plant growth promoting bioinoculants on morphological parameters 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. Among all citrus species, Pant lemon-1 recorded the minimum days for leaf initiation (23.69 days), maximum average number of leaves (21), maximum number of branches (7.25) and maximum plant height (37.79 cm) as compared to Kinnow and Grapefruit after the application of plant growth promoting bioinoculants.
