The effect of dose and period of decomposition of neem seed powder, neem cake and neem dry leaf power on root-knot infection and growth of tomato plant was studied. It was observed that all neem derivatives significantly not only reduced the intensity of root-knot disease but also improved plant growth. The significant effects of these organic amendments increased gradually as the dose and period of decomposition increased. Maximum reduction in the reduction of root-knot index and improvement in plant growth was recorded where neem cake was used @ 1.0% and allowed to decompose for 20 days.
