PSB, LSD, SSP, FYM, PM and ns denote phosphate solubilizing bacteria, least significant difference, single super phosphate, farmyard manure, poultry manure and non-significant interaction, respectively.
Means with different letter in each column are significantly different at p ≤ 0.05.
Single asterisk stands for significant, Double asterisk stands for higly significant, Triple asterisk stands for very higly significant.
