Efficacy of different soil amendment on disease incidence of dry root rot of chickpea during year 2017-2018

Abstract

Chickpea (Cicer arietinum L.) is an important pulse crop of India popularly known as Gram. Dry root rot of chickpea is the most severe disease in the central and southern zone, where the crop is mostly grown under rainfed condition. Rhizoctonia bataticola (Taub.) Butler is one of the most distructive pathogen causing dry root rot disease in chickpea. The efficacy of different soil amendment viz., Neem oil cake, Mustard oil cake, Linseed oil cake, Saw dust and Parthinium were evaluated for the management of dry root rot disease of chickpea in pot condition during 2017-18. Among the amendment, Neem oil cake was found effective in reducing the disease incidence, delay the appearance of disease and increase in germination, fresh and dry plant weight, number of branches/plant, number of pods/plant, plant height(cm), test weight (100 seed) and yield (gm)/plant. Among the amendment Neem oil cake was found most effective which delayed appereance of symptoms till 110 days after sowing (DAS) and maximum seed germination (92.67%) as compared to control 85 DAS and seed germination (80.0%) during 2017-2018.
