Effect of different organic amendments for the management of root-knot nematode, Meloidogyne Incognita on carrot

A field experiment was conducted on carrot var., ‘Early Nentes’, with four organic amendments in two doses viz., sawdust, neem cake, poultry manure each @ 1.0 and 1.5 ton ha⁻¹ and water hyacinth @ 1.0 and 2.0 ton ha⁻¹ Results revealed that all organic amendments were found to be effective in reducing the galls, final nematode population and forked tap root of carrot and subsequently increased the yield and yield attributing characters of carrot. Further, among all organic amendments, neem cake was found significantly superior at both the doses i.e. 1.0 and 1.5 t ha⁻¹ in reducing the nematode population and increased yield of carrot followed by sawdust, poultry manure and water hyacinth at higher doses.
