The Presence of Soil Pathogens in Chickpea (Cicer Arietinum L.) Growing in Winter and Summer.

Abstract

The aim of this study was to reveal the presence of soil pathogens in chickpea growing in winter and summer. Field trials were arranged as randomized blocks in design with four replications in Diyarbakır province during 2017 year. Sowing dates were November 16 for winter and March 10 for summer. Chickpea plants in all the plots were examined for root rot and wilting in the first week of June. Isolation was made from diseased plants and the diagnosis was performed macroscopically and microscopically. Macrophomina phaseoli, Rhizoctonia solani, Phoma spp., Fusarium oxysporum, Fusarium solani and Fusarium spp., were isolated in both trials but the rates were different. Chickpea plants were more affected by summer sowing than winter sowing and athe most isolated pathogens were Fusarium species, especially Fusarium oxysporum.
