Bio-inoculants have been used for enhancing plant growth in horticultural crops even in nutrient-limited soils. The present research evaluated the effect of inoculation of two growing media with six biofertilizer consortia on the growth and buddability of ‘Rough lemon’ rootstock subsequently budded with ‘Kinnow’ mandarin variety. Soil + FYM + Cocopeat (SFC) with Azospirillum (Azo) + AM fungi consortium improved seed germination, seedling growth, chlorophyll, P, K, root growth, root epidermis, and cortical region thickness; xylem and phloem diameter in rough lemon; budding success and growth in Kinnow mandarin saplings. It also increased OC, P, and K levels in growing media. AM spore count and AM root colonization showed a positive correlation with budding success, root P and soil P content. SFC fortified with Azo + AM fungi resulted in better growth and buddability of rough lemon seedlings along with better growth of Kinnow mandarin saplings.
