Abstract
A field experiment was conducted to know the field response of selected commercial tree species to phosphorus solubilizing and mobilizing bioinoculants with graded levels of phosphorus was carried out in Biofuel unit, University of Agricultural sciences, Bengaluru, during 2021-22. The experiment was laid out in CRD with 08 treatments replicated thrice. Plants treated with 50 per cent recommended dose of phosphorus + phosphorus solubilizing fungus (Glomus aggregatum)+ phosphorus solubilizing bacteria (Pseudomonas striata) (T8) in plants C. inophyllumI, S. mahagoni, M. dubia, A. polystachya recorded significantly maximum plant height (14.10, 55.37, 35.40 and 73.19cm), number of leaves (39.33, 35.33, 62.67, 65.33), leaf area (49.19, 60.26, 16.82, 62.10cm2), collar diameter (15.32, 23.34, 11.83 and 13.75 mm), dry matter (29.34, 7.78, 3.94 and 4.74 g/plant at 90 DAP)
