Control of Plant Parasitic Nematodes Associated with Linseed by Oil Seed Cakes and Ploughing

The addition of organic matter to soil has been explored as an alternative means of nematode control. Oil seed cakes of neem/margosa (Azadirachta Indica A. Juss), groundnut (Arachis hypogaea L.), castor (Ricinus communis L.), mustard (Brassica campestris L.), rocket salad/duan (Eruca sativa Mill) were highly effective in reducing the multiplication of nematodes. Consequently plant growth and oil content of linseed (Linum usitatissimum Linn) increased significantly. Nematode multiplication rate was further reduced when oil-cakes were added with deep ploughing.
