Among the biological control agents, <i>T. harzianum</i> resulted in the greatest shoot and root lengths (106.54 and 82.45 cm, respectively), and lowest number of cysts (56.00/kg of soil). Among the neem products, neem cake recorded the greatest increase in the length and weight of shoot and root. Nodulation was greatest for neem seed powder. The lowest number of cysts was observed in plants treated with neem cake (52.00) and neem seed powder (54.00). The results indicated the potential of <i>T. harzianum</i> combined with neem cake in the management of <i>H. cajani</i>. 收起
