MYCORRHIZAL EFFECT ON ROOT ROT OF CHICKPEA CAUSED BY Rhizoctonia bataticola.

Abstract

The present investigation was carried out to study the effect of mycorrhiza on root rot of chickpea. Root nodule, root colonization by VAM, spore density of VAM, root rot incidence by Rhizoctonia bataticola and population of Rhizoctonia bataticola were recorded at 15, 30, 45, 60 and 75 DAS. The number of nodules/ plant was recorded as 4.4, 6.2 and 8.0 at 30, 45 and 60 DAS respectively in its treatment of VAM @ 5kg/ha. The maximum number of mycorrhizal spores was observed in treatment of VAM alone @ 5kg/ha i.e. 17.3, 21.0, 24.7, 27.7, 30.7 followed by combined application of VAM + seed treatment with Trichoderma @ 4g/kg (12.7, 16.3, 20.0, 22.3 and 25.0) at 15, 30, 45, 60 and 75 DAS respectively.
