Abstract:
Soybean is the main crop of Madhya Pradesh covered 55-60% share of the total production. Gradually soybean production and their quality go down due to unfavorable climatic condition and occurrence of biotic and a biotic factors. An extensive surveyed was done during the crop period from seedling stage to pod formation stage in the kharif 2017. and found that nearly 63 percent of crop was damaged in due to occurrence of charcoal rot A field experiment was conducted to study the efficacy of bio-agent and the chemical fungicides for the management of charcoal rot in two successive soybean seasons in kharif 2018-19 and 2019-20.Pooled mean data of both years on disease management indicated that bio-agent and fungicides alone and in combinations significantly reduced the incidence of charcoal rot disease in comparison to untreated control. Seeds treated with Trichoderma viride and plant sprayed by Azoxystoribin at pod formation stage gave maximum disease control (89.41%) followed by seed treatment with Pseudomonas fluorescens and sprayed by Tebuconozole (84.07%). whereas seed treated with thiram and plant sprayed with Carbendazim showed 70.71% disease control. Application of farm yard manure before sowing and soil treated with T. viride reduced 73.21% disease incidence. Maximum grain yield (13.94q/ha and 17.12q/ha) was obtained in T. viride and azoxystorbin treated plot in both the experimental years 2018-19 and 2019-20. This treatment not only gave the highest yield but also gave higher return.
