Abstract

A field experiment on the management of charcoal rot caused by Macrophomina phaseolina (Tassi.) Goid of sorghum by utilising various soil amendments revealed that the combined treatment of straw mulch + neem cake + seed treatment with Trichoderma viride Pers. Ex. Fries recorded 7.4 per cent charcoal rot incidence, 18.0 per cent lodging, 0.76 nodes infection and 45.0 per cent senescence as compared to the untreated control (SPV-86) having 33.0 per cent charcoal rot, 52.3 per cent lodging, 2.1 nodes infection and 75 per cent senescence. Significantly higher grain yield was obtained from the combined treatment (1913 kg/ha) as against the untreated control (1412 kg/ha). The next best treatments were straw mulch + neem cake, straw mulch + seed treatment with T. viride and straw mulch alone. However, management of charcoal rot by straw mulch alone works out to be economical and effective.
