Aflatoxin contamination in field mustard (Brassica juncea) cultivars.

7 varieties of mustards were cultivated in statistically designed field during 1988 through 1989 and 1989 through 1990 crops in order to ascertain the resistant or less susceptible varieties for aflatoxin elaboration. Under field condition, none of the varieties of mustard was found to be resistant. Maximum aflatoxin contamination was observed in the late planting time (15 th November) crops. Insect (Lipaphis erysime) incidence had significant negative correlation (r=-0.9354) with the yield (Q/hectare) while it had significant positive correlation (r=0.5705) with aflatoxin contamination.
