Abstract:

Rapeseed – mustard is one of the most important cruciferous oilseed crops   basically raise for oils and vegetables to meet domestic consumption of marginal farmers during rabi  season in Manipur.  Field experiments were conducted under organic condition for two consecutive years ( 2014 & 2015) during rabi seasons  at Kakching. Weekly surveys detected   white rust of rapeseed –mustard  on the four varieties  used. Amendments of agronomic practices including sowing dates, intercropping and plant density besides addition  of soil with FYM (Farmyard Manure) were found effective on fungal disease of the crop.  The disease parameters were monitored  through disease incidence (DI) and disease severity (DS) assessment technique.  The least disease severity (9.57%) was found in plant density followed by date of sowing (11.06%) and   intercropping (12.29%). White rust caused by Albugo candida attacked  the crop from  mild to severe form and the effect of agronomic practices applied  were significant in controlling the white rust  disease of the crop.
