Abstract
In vitro and planta field experiments were conducted to check the effect of Trichodermaharzianum organic amendments in controlling chickpea’s major soil-borne diseases. T. harzianum, isolate Tri-9 was selected for its in vitro efficacy against Sclerotium rolfsii and Rhizoctonia solani the causal organisms of important chickpea diseases in the field. Subsequently, spore suspension and wheat grain colonized inoculum of isolate Tri-9 were prepared for further planta use. Three different organic amendments such as poultry refuse, cow dung, and mustard oil cake after being fortified with wheat grain colonized T. harzianum isolate Tri-9. Both the fortified soil amendments and Tri-9 spore suspensions were checked in the chickpea growing field under natural conditions. Besides disease suppression, the growth-promoting parameters and yield were also recorded. Trichoderma fortified poultry refuge was found significantly effective in plummeting pre-and post-emergence seedling mortality, disease incidence, and severity. All the treatments significantly increased the growth-promoting components, yield, and improved seed quality compared to those of untreated control. Trichoderma fortified compost mixed with poultry refuge was the best to control soil-borne diseases of chickpea as well increase yield and their quality.
