Abstract:
Experiments on the effect of neem products and vermicompost on root- knot nematode Meloidogyne incognita population build-up in tomato was carriedout and observations on the nrmatode population on root and soil, number of galls, eggs/eggmass total nematode population and nematode multiplication factor were recorded. The observations revealed that all the parameters showed significant in root and shoot weight and reduction in the nematode population multiplication rate under pot condition in tomato crop. The highest reduction in nematode multiplication in comparison to the inoculated check was observed in carbofuran treated check (1.99) followed by the Achook @ 5% (2.19), neem cake @ 5% (2.50), neem leaf compost (2.68), neem leaf compost (2.68), vermi compost (3.14) and 3.38 in neem leaf with decomposer with the minimum reduction 4.50 observed in inoculated check respectively in ascending order. The percentage decrease in nematode multiplication factor was observed maximum (55.77) in Carbofuran treated check followed by 51.33% in Achook, 44.44% in neem cake, 40.44% in neem leaf compost, 30.22 in vermi compost and minimum 24.88% in neem leaf with organic decomposer treatment in comparison to the inoculated check. Similar trends in the observations of root weight, shoot weight and gall formation was recorded.
