Abstract

Studies were carried out to see influence of organic amendments and fungicides on population dynamics of fungi in chickpea out in the field and in vitro condition, its management using organic amendments such as FYM, neem cake and kranj cake and bio-agents like Trichoderma. Evaluation of antagonistic potential of Trichoderma against the pathogen was also carried out. It is known to be infected by 52 pathogens the world over and 32 in India. Many soil-borne pathogens such as Fusarium oxysporum, F. solerotium rolfsii, Sclerotinia sclerotiorum, Rhizoctonia solani, R. Bataticola, and Pythium sp. reduce the plant stand and these large numbers of pathogens affect the yields. Among 20 treatments, treatment comprising vermicompost with Trichoderma shows better result against growth of F. oxysporum and S. rolfsii in field as well as in vitro condition. Treatment in which varmicompost 2.5 q/ha with Trichoderma supplied shows minimum population of wilt (13.33), collar rot (11.67) on field respectively, whereas on Fusarium selective media, population of Fusarium recorded minimum (6433) over rest of the treatments. Trichoderma shows its maximum growth under treatment vermicompost 2.5 q/ha with Trichoderma which exhibits antagonistic effect against F. oxysporum and S. rolfsii. The population of F. oxysporum and S. rolfsii recorded maximum in the controlled treatment on field and in vitro respectively. Soil pH, moisture, temperature and organic matter exhibit their indirect as well as direct effect on population of F. oxysporum and S. rolfsii
