Gram (Cicer arietinum L.), an important pulse crop in India suffers from several diseases of which dry root rot caused by Rhizoctonia solani is of economic importance. Field experiments were conducted during Rabi (post rainy season) of 2012-13, 2013-14 and 2014-15 to develop a suitable organic module to manage this disease and to improve productivity of gram. The treatments included a uniform treatment soil application of neem cake @ 2 q ha-1 + seed treatment to avoid any insect infestation in all the treated plots. Individual treatments included seed treatment, drenching and soil application separately and in combination of soil antagonists (local resident Trichoderma viride and bacteria). Different organic methods of disease management exhibited significant effect on dry root rot incidence. The minimum percent root rot infested plant (6.54 %) and maximum seed yield (1642 kg ha-1) was observed in module consisting of seed treatment with T. viride (8 g/kg seed) +soil application of T. viride (2 kg ha-1) incubated on FYM + drenching of T. viride (10 g /l) followed by 6.83 % dry root rot infested plants and 1584 kg ha-1 seed yield in module consisting of T. viride (2 kg ha-1) incubated on FYM alone. However, no significant difference could be observed in these two treatments. All the treatments were found significantly superior over untreated control (21.12% infested plants and seed yield 979 kg ha-1). The organic module resulted in 1.5 times higher B: C ratio over the untreated control.
