Abstract: The present study enumerates the floristic diversity of weeds growing in the fields of two major crops rice and wheat in Sonbhadra district of Uttar Pradesh. The survey conducted during 2012-2017 recorded 78 angiospermic weed species which belong to 70 genera and 36 families. Of these, dicotyledonous weeds are represented by 50 species under 50 genera and 29 families whereas monocotyledonous weeds are represented by 28 species under 20 genera and 7 families. Out of total species found in the district in these two crops, 37 species are native to India, 36 species are exotic and for remaining 5 species the nativity is not clear. During kharif season in the rice crop 57 species under 47 genera and 28 families and during rabi season in the wheat crop 21 species under 19 genera and 12 families were observed. Only six species have been found growing in both crops in both seasons. During the survey it was also observed that about 14 species were used by local people as vegetables and about 32 species as fodder for animals. Apart from this, about 64 species considered as medicinal are also found in these two crops. Most of the species were found common and as per IUCN, 25 species have been listed under ‘least concern’ category. For each species correct name with family, local name, nativity, flowering and fruiting periods and reference to voucher specimens have been provided.
