A pot experiment was conducted to study the growth and mycorrhizal dependence (MD) of eight selected pulses (blackgram, bushbean, chickpea, cowpea, gardenpea, grasspea, lentil, and mungbean), and two oil seeds (groundnut and soybean). Soil was collected from the research farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, Bangladesh. The arbuscular mycorrhizal (AM) dependence of the crops was evaluated based on growth parameters, spore population and root colonization. A positive growth response to AM was observed in all the crops. The shoot dry weight and number of pods of the inoculated crops were increased by 48 and 141%, respectively, at 50% flowering stage compared to the uninoculated control. Mycorrhizal colonization differed among the crops ranging from 46.6 to 83.3% along with spore abundance in the rhizosphere soil ranging from 15.0 to 314.0 100g-1soil. The mycorrhizal dependence (MD) varied from 25.27 to 50.79%. Two groups of plants were marked according to their MD: (i) the highly dependent plants with an MD>30% (bushbean, chickpea, cowpea, gardenpea, grasspea, groundnut, lentil and mungbean) and (ii) the intermediate group plants with an MD between 10-30% (blackgram and soybean).
