Sugarcane molasses and ash were evaluated for the management of root knot nematode under screen house conditions.The pots were filled with sterilized potting mixture of 1 ∶ 1 ∶ 1 of clay, silt and FYM.Sugarcane molasses and ash were mixed at 10, 20 and 30 g/kg of soil and 10,20, and 30 mL/kg of soil twenty one days before transplantation, except pots used as positive and negative control.The tomato plants were inoculated with 2 000 eggs per plant after one week of transplantation when the plants became established.After seven weeks of inoculation, data were recorded on various parameters.The results revealed that both the organic amendments were effective in reducing gall per plant, galling index, eggs per egg mass, egg masses per plant and fresh and dry root weight compared to controls.The highest reduction in galls per plant was shown by the application of molasses, when applied at 30 mL/kg of soil (26.40), followed by ash (28.20).The shoot length of plant was enhanced by the molasses (73.73 cm) followed by ash (70.00 cm).The shoot and root length, fresh and dry shoot weight of plants were increased effectively in amended soil under uninoculated conditions showing the stimulatory effects.The sugarcane molasses used at 30 mL/kg of soil showed best results, followed by ash used 30g/kg of soil.No phytotoxicity of the amendments has been noted on plants and they are therefore safe for plants.
