The effect of organic amendments on susceptible potato cultivars FD-8-1 inoculated with Meloidogyne incognita was investigated using sugarcane bagasse, kanair leaves, neem seeds powder, saw dust and caster cake in pot experiment. Number of galls and egg masses were found less on the roots of the plants planted in all amended soils. Plants grown in amended soils with kanair leaves, neem seed powder, saw dust and caster cake had same number of galls and egg masses, higher than that of plants in sugarcane bagasse. The neem seed amended soil was most effective in lowering the number of female. The production of egg masses by the adult female was 60.6% less on the roots of plants in neem amended soil. Neem amendment was 1.5, 1.2, 1.5 and 1.1 times more effective to that of sugarcane bagasse, kanair leaves, saw dust and caster cake respectively. The plants in the soil amended with neem and saw dust produced 58.4% and 33.7% less root galls, respectively. The lower number of galling and egg masses in neem amended soil indicated to be best amendment.
