EFFECT OF INTERCROPPING ON THE INCIDENCE OF DISEASES OF GROUNDNUT

Abstract

                                The effect of intercropping on the incidence of groundnut ring mosaic caused by a strain of Tomato Spotted Wilt Virus (TSWV) could be seen only at 30 days after sowing. Sorghum as intercrop and barrier crop, cumbu as intercrop in groundnut significantly reduced the incidence of ring mosaic, late leaf spot and rust. Sunflower either as intercrop or barrier crop in groundnut was not effective in reducing the incidence of all the three diseases.

Key words : Groundnut diseases, intercropping
