Assessment and Demonstrations on Management of Stem Rot Disease in Mustard Crop

Rapeseed- mustard is an important edible oilseed crop among nine major oilseed crops i.e. soybean, groundnut, sunflower, safflower, sesame, caster, linseed, rapeseed mustard & niger. Rapeseed-mustard group of crops has diversified domestic and industrial uses. Rapeseed mustard is the third most important source of vegetable oil in the world and is grown in more than 50 countries across the globe. The present study was carried out to assess and demonstrate the management technology of stem rot disease in mustard. The seed treatment with Carbedazim @ 2.0 g/kg seed controlled stem rot disease more efficiently in mustard crop among two recommended practices i.e. Soil treatment @ 9.75 kg/ha followed by seed treatment @ 5 g/kg seed with Trichoderme harzinium and only Seed treatment with Carbendazim @ 2.0 g/kg. The demonstration of thee years resulted 18.9 percent average increase in yield of mustard crop and 22% higher net returns over checkplots. The front line demonstration on management of stem rot disease on mustard as seed treatment with Carbendazim resulted 2.76 q/ha higher yield and farmers got Rs. 8303/- additional return over farmers field (Without seed treatment). The Average extension gap was observed 2.68 q/ha, which emphasized the need to educate the farmers through various extension means for adoption of improved agricultural technologies, to bridge the wide extension gap. The technology index varied from 21 to 51 percent. The average technology index of 3 years was 41.33 percent.
